constants - Error numbers (e.g. EINVAL) are now constants - Signal numbers (e.g. SIGINT) are now constants - fcntl() file locks now work properly on Windows - Significantly improve Windows path handling code - Implement true vfork() on Windows and make fork() faster - Implement scanf %[charset] support and improve conformance - Introduce $COSMOSDRIVE so you can use Windows 11 dev drives - Fix stdio seek/tell bug and make stdio locks faster and safer - Change TLS ABI to use tlscc wrapper that inserts function calls - Make malloc() faster on all platforms using new cosmo_shard() api - Make malloc() fast like tcmalloc on Linux using restartable sequences - Improve fsync() and fdatasync() polyfills so they abstract robustness - Fix CLOCK_BOOTTIME and CLOCK_MONOTONIC on XNU so it reflects uptime - Fix bugs in Windows overlapped code that could possibly cause crash - Fix bugs in Windows signal code that could possibly cause crash - Make symlinks with multiple components work right on Windows - Add FreeBSD ELF note to remove SIGBUS issue and other quirks - Support symlinks on Windows under non-administrator accounts - Make kisdangerous() scalable by adding radix trie to mmap() - Make large realloc() operations zero-cost on all platforms - Fix bugs in readdir() on Windows where d_reclen wasn't set - Make all system call wrappers memory safe (raises EFAULT) - Fix bugs in poll() and select() on Windows with 64+ fds - Fix bug in madvise() on Windows that could cause crash - Support WUNTRACED, SIGSTOP, and SIGCONT on Windows - Increase x86 image base from 0x400000 to 0x4200000 - Introduce -msysv and -mtinylinux flags to cosmocc - Fix issues with siglongjmp() on XNU and NetBSD - Make pthread_barrier_wait() work correctly - Make clock_gettime() faster on FreeBSD ARM - Support file mode bits better on Windows - Improve performance of string libraries - Raise EILSEQ when creating evil paths - Fix std::terminate to not use malloc - Modernize more c11 and c23 features - Make pthread_once() exception safe - Support RLIMIT_CPU on Windows - Introduce HACL* cryptography - Introduce cosmopolitan make - Introduce fasterzip program - Introduce open_memstream() -

Needless to say, `mprotect()` needs to be -a privileged function, so that it can be used to disable the execute bit -on all other parts of the executable except for the privileged section, -thereby making it writable. Once this has been done, code can change. - -On Windows the displacement bytes of the TLS instruction are changed to -use the `%gs:0x1480+i*8` ABI where `i` is a number assigned by the WIN32 -`TlsAlloc()` API. This avoids the need to call `TlsGetValue()` which is -implemented this exact same way under the hood. Even though 0x1480 isn't -explicitly documented by MSDN, this ABI is believed to be stable because -MSVC generates binaries that use this offset directly. The only caveat -is that `TlsAlloc()` must be called as early in the runtime init as -possible, to ensure an index less than 64 is returned. +When Windows and MacOS aren't in the support vector, then the above +assembly rewriting pass can be avoided entirely, and the binary can +simply use the TLS opcodes that GCC and Clang generate for Linux. ### Thread Information Block (TIB) diff --git

Raise ENOTDIR based on trailing slash and then remove it + * + * The result of this function, is an absolute normalized path is placed + * in `path16` that's going to be safe to pass to 99% of WIN32 APIs. The + * unicode or "W" suffixed APIs are preferred, even though our UNIX APIs + * always use UTF-8. So the first thing UNIX system call wrappers do, on + * Windows, is call this function. + * + * This function does pure normalization. UNIX kernels normally do i/o + * checks as they're normalizing a path. For example, if `foo` is a + * regular file, and you try to open `foo/bar/../` then Cosmo Windows + * will pretend nothing's wrong, since this routine normalized it away, + * however a UNIX kernel would notice that `bar` isn't an existant dir + * during the normalization process. Cosmopolitan doesn't polyfill this + * error checking. However an exception is made for one particularly + * important case, which is paths that have a trailing slash. If you + * pass this function `"foo/"` rather than `"foo"` then a quick i/o + * check will be performed to ensure `foo` is either a directory or a + * directory symlink; otherwise ENOTDIR will be raised. + * + * You should use UNIX style paths with Cosmopolitan's UNIX system call + * wrappers. However this routine ensures you can pass DOS or UNC style + * paths if the need arises. For example, open("C:\\foo\\bar") is the + * same as saying open("/C/foo/bar"). This function essentially treats + * forward slash and backslash as the same thing, so you could even say + * open("C:/foo/bar") and it would have the same effect. You can prefix + * these paths like open("\\\\?\\C:\\foo\\bar") however it is not needed + * because this function determines when that special prefix is / isn't + * needed, and will add / remove it as necessary automatically. + * + * Windows doesn't have a concept of NAME_MAX (which is usually 255 on + * UNIX systems) so your file and folder names could be 500 characters + * long or more if you want. + * + * This routine does enforce the PATH_MAX limit, which does apply to + * Windows. As of this writing, it's 1024 characters, which is the + * minimum required for POSIX conformance. While you can normally get + * away with using longer paths on systems that support it, Cosmo i/o + * routines use stack buffers to manipulate paths which will raise + * ENAMETOOLONG when this limit is violated. The WIN32 API normally + * imposes a 260 character limit on DOS style paths, but this function + * works around that by prepending a magic `\\?\` prefix to an absolute + * normalized DOS-style path only when necessary. Our technique should + * allow in the future for PATH_MAX to potentially be as high as 32768 + * however we're quite happy keeping the limit at 1024 for now. + * + * DOS style drive relative paths are not supported. This means you + * can't use paths like `A:foo/bar` and expect it to do the right thing. + * This function will raise an ENOTSUP error if such a path is passed. + * If your path starts with a letter followed by a colon, then the next + * character must be a slash or backslash. + * + * This function will raise EILSEQ if the final path component ends with + * the space or period character. UNIX allows such paths, but Windows + * will remove those trailing characters as part of the normalization + * process.

export ENV +.Pp +substituting for +.Dq .shinit +any filename you wish. +.Pp +If command line arguments besides the options have been specified, then +the shell treats the first argument as the name of a file from which to +read commands (a shell script), and the remaining arguments are set as the +positional parameters of the shell ($1, $2, etc). +Otherwise, the shell +reads commands from its standard input. +.Ss Argument List Processing +All of the single letter options that have a corresponding name can be +used as an argument to the +.Fl o +option. +The set +.Fl o +name is provided next to the single letter option in +the description below. +Specifying a dash +.Dq - +turns the option on, while using a plus +.Dq + +disables the option. +The following options can be set from the command line or +with the +.Ic set +builtin (described later). +.Bl -tag -width aaaallexportfoo -offset indent +.It Fl a Em allexport +Export all variables assigned to. +.It Fl c +Read commands from the +.Ar command_string +operand instead of from the standard input. +Special parameter 0 will be set from the +.Ar command_name +operand and the positional parameters ($1, $2, etc.) +set from the remaining argument operands. +.It Fl C Em noclobber +Don't overwrite existing files with +.Dq \*[Gt] . +.It Fl e Em errexit +If not interactive, exit immediately if any untested command fails. +The exit status of a command is considered to be +explicitly tested if the command is used to control an +.Ic if , +.Ic elif , +.Ic while , +or +.Ic until ; +or if the command is the left hand operand of an +.Dq && +or +.Dq || +operator. +.It Fl f Em noglob +Disable pathname expansion. +.It Fl n Em noexec +If not interactive, read commands but do not execute them. +This is useful for checking the syntax of shell scripts. +.It Fl u Em nounset +Write a message to standard error when attempting to expand a variable +that is not set, and if the shell is not interactive, exit immediately. +.It Fl v Em verbose +The shell writes its input to standard error as it is read. +Useful for debugging. +.It Fl x Em xtrace +Write each command to standard error (preceded by a +.Sq +\ ) +before it is executed. +Useful for debugging. +.It Fl I Em ignoreeof +Ignore EOF's from input when interactive. +.It Fl i Em interactive +Force the shell to behave interactively. +.It Fl l +Make dash act as if it had been invoked as a login shell. +.It Fl m Em monitor +Turn on job control (set automatically when interactive). +.It Fl s Em stdin +Read commands from standard input (set automatically if no file arguments +are present). +This option has no effect when set after the shell has +already started running (i.e. with +.Ic set ) . +.It Fl V Em vi +Enable the built-in +.Xr vi 1 +command line editor (disables +.Fl E +if it has been set). +.It Fl E Em emacs +Enable the built-in +.Xr emacs 1 +command line editor (disables +.Fl V +if it has been set). +.It Fl b Em notify +Enable asynchronous notification of background job completion. +(UNIMPLEMENTED for 4.4alpha) +.El +.Ss Lexical Structure +The shell reads input in terms of lines from a file and breaks it up into +words at whitespace (blanks and tabs), and at certain sequences of +characters that are special to the shell called +.Dq operators . +There are two types of operators: control operators and redirection +operators (their meaning is discussed later). +Following is a list of operators: +.Bl -ohang -offset indent +.It "Control operators:" +.Dl & && \&( \&) \&; ;; | || \*[Lt]newline\*[Gt] +.It "Redirection operators:" +.Dl \*[Lt] \*[Gt] \*[Gt]| \*[Lt]\*[Lt] \*[Gt]\*[Gt] \*[Lt]& \*[Gt]& \*[Lt]\*[Lt]- \*[Lt]\*[Gt] +.El +.Ss Quoting +Quoting is used to remove the special meaning of certain characters or +words to the shell, such as operators, whitespace, or keywords. +There are three types of quoting: matched single quotes, +matched double quotes, and backslash. +.Ss Backslash +A backslash preserves the literal meaning of the following +character, with the exception of +.Aq newline . +A backslash preceding a +.Aq newline +is treated as a line continuation. +.Ss Single Quotes +Enclosing characters in single quotes preserves the literal meaning of all +the characters (except single quotes, making it impossible to put +single-quotes in a single-quoted string). +.Ss Double Quotes +Enclosing characters within double quotes preserves the literal +meaning of all characters except dollarsign +.Pq $ , +backquote +.Pq ` , +and backslash +.Pq \e . +The backslash inside double quotes is historically weird, and serves to +quote only the following characters: +.Dl $ ` \*q \e \*[Lt]newline\*[Gt] . +Otherwise it remains literal. +.Ss Reserved Words +Reserved words are words that have special meaning to the +shell and are recognized at the beginning of a line and +after a control operator. +The following are reserved words: +.Bl -column while while while while while -offset indent +.It ! Ta elif Ta fi Ta while Ta case +.It else Ta for Ta then Ta { Ta } +.It do Ta done Ta until Ta if Ta esac +.El +.Pp +Their meaning is discussed later. +.Ss Aliases +An alias is a name and corresponding value set using the +.Xr alias 1 +builtin command. +Whenever a reserved word may occur (see above), +and after checking for reserved words, the shell +checks the word to see if it matches an alias. +If it does, it replaces it in the input stream with its value. +For example, if there is an alias called +.Dq lf +with the value +.Dq "ls -F" , +then the input: +.Pp +.Dl lf foobar Aq return +.Pp +would become +.Pp +.Dl ls -F foobar Aq return +.Pp +Aliases provide a convenient way for naive users to create shorthands for +commands without having to learn how to create functions with arguments. +They can also be used to create lexically obscure code. +This use is discouraged. +.Ss Commands +The shell interprets the words it reads according to a language, the +specification of which is outside the scope of this man page (refer to the +BNF in the +.Tn POSIX +1003.2 document). +Essentially though, a line is read and if the first +word of the line (or after a control operator) is not a reserved word, +then the shell has recognized a simple command. +Otherwise, a complex +command or some other special construct may have been recognized. +.Ss Simple Commands +If a simple command has been recognized, the shell performs +the following actions: +.Bl -enum -offset indent +.It +Leading words of the form +.Dq name=value +are stripped off and assigned to the environment of the simple command. +Redirection operators and their arguments (as described below) are +stripped off and saved for processing. +.It +The remaining words are expanded as described in +the section called +.Dq Expansions , +and the first remaining word is considered the command name and the +command is located. +The remaining words are considered the arguments of the command. +If no command name resulted, then the +.Dq name=value +variable assignments recognized in item 1 affect the current shell. +.It +Redirections are performed as described in the next section. +.El +.Ss Redirections +Redirections are used to change where a command reads its input or sends +its output. +In general, redirections open, close, or duplicate an +existing reference to a file. +The overall format used for redirection is: +.Pp +.Dl [n] Va redir-op Ar file +.Pp +where +.Va redir-op +is one of the redirection operators mentioned previously. +Following is a list of the possible redirections. +The +.Bq n +is an optional number between 0 and 9, as in +.Sq 3 +(not +.Sq Bq 3 ) , +that refers to a file descriptor. +.Bl -tag -width aaabsfiles -offset indent +.It [n] Ns \*[Gt] file +Redirect standard output (or n) to file. +.It [n] Ns \*[Gt]| file +Same, but override the +.Fl C +option. +.It [n] Ns \*[Gt]\*[Gt] file +Append standard output (or n) to file. +.It [n] Ns \*[Lt] file +Redirect standard input (or n) from file. +.It [n1] Ns \*[Lt]& Ns n2 +Copy file descriptor n2 as stdin (or fd n1). +.It [n] Ns \*[Lt]&- +Close standard input (or n). +.It [n1] Ns \*[Gt]& Ns n2 +Copy file descriptor n2 as stdout (or fd n1). +.It [n] Ns \*[Gt]&- +Close standard output (or n). +.It [n] Ns \*[Lt]\*[Gt] file +Open file for reading and writing on standard input (or n). +.El +.Pp +The following redirection is often called a +.Dq here-document . +.Bl -item -offset indent +.It +.Li [n]\*[Lt]\*[Lt] delimiter +.Dl here-doc-text ... +.Li delimiter +.El +.Pp +All the text on successive lines up to the delimiter is saved away and +made available to the command on standard input, or file descriptor n if +it is specified. +If the delimiter as specified on the initial line is +quoted, then the here-doc-text is treated literally, otherwise the text is +subjected to parameter expansion, command substitution, and arithmetic +expansion (as described in the section on +.Dq Expansions ) . +If the operator is +.Dq \*[Lt]\*[Lt]- +instead of +.Dq \*[Lt]\*[Lt] , +then leading tabs in the here-doc-text are stripped. +.Ss Search and Execution +There are three types of commands: shell functions, builtin commands, and +normal programs \(en and the command is searched for (by name) in that order. +They each are executed in a different way. +.Pp +When a shell function is executed, all of the shell positional parameters +(except $0, which remains unchanged) are set to the arguments of the shell +function. +The variables which are explicitly placed in the environment of +the command (by placing assignments to them before the function name) are +made local to the function and are set to the values given. +Then the command given in the function definition is executed. +The positional parameters are restored to their original values +when the command completes. +This all occurs within the current shell. +.Pp +Shell builtins are executed internally to the shell, without spawning a +new process. +.Pp +Otherwise, if the command name doesn't match a function or builtin, the +command is searched for as a normal program in the file system (as +described in the next section). +When a normal program is executed, the shell runs the program, +passing the arguments and the environment to the program. +If the program is not a normal executable file (i.e., if it does +not begin with the "magic number" whose +.Tn ASCII +representation is "#!", so +.Xr execve 2 +returns +.Er ENOEXEC +then) the shell will interpret the program in a subshell. +The child shell will reinitialize itself in this case, +so that the effect will be as if a +new shell had been invoked to handle the ad-hoc shell script, except that +the location of hashed commands located in the parent shell will be +remembered by the child. +.Pp +Note that previous versions of this document and the source code itself +misleadingly and sporadically refer to a shell script without a magic +number as a "shell procedure". +.Ss Path Search +When locating a command, the shell first looks to see if it has a shell +function by that name. +Then it looks for a builtin command by that name. +If a builtin command is not found, one of two things happen: +.Bl -enum +.It +Command names containing a slash are simply executed without performing +any searches. +.It +The shell searches each entry in +.Ev PATH +in turn for the command. +The value of the +.Ev PATH +variable should be a series of entries separated by colons. +Each entry consists of a directory name. +The current directory may be indicated +implicitly by an empty directory name, or explicitly by a single period. +.El +.Ss Command Exit Status +Each command has an exit status that can influence the behaviour +of other shell commands. +The paradigm is that a command exits +with zero for normal or success, and non-zero for failure, +error, or a false indication. +The man page for each command +should indicate the various exit codes and what they mean. +Additionally, the builtin commands return exit codes, as does +an executed shell function. +.Pp +If a command consists entirely of variable assignments then the +exit status of the command is that of the last command substitution +if any, otherwise 0. +.Ss Complex Commands +Complex commands are combinations of simple commands with control +operators or reserved words, together creating a larger complex command. +More generally, a command is one of the following: +.Bl -bullet +.It +simple command +.It +pipeline +.It +list or compound-list +.It +compound command +.It +function definition +.El +.Pp +Unless otherwise stated, the exit status of a command is that of the last +simple command executed by the command. +.Ss Pipelines +A pipeline is a sequence of one or more commands separated +by the control operator |. +The standard output of all but +the last command is connected to the standard input +of the next command. +The standard output of the last +command is inherited from the shell, as usual. +.Pp +The format for a pipeline is: +.Pp +.Dl [!] command1 [ | command2 ...] +.Pp +The standard output of command1 is connected to the standard input of +command2. +The standard input, standard output, or both of a command is +considered to be assigned by the pipeline before any redirection specified +by redirection operators that are part of the command. +.Pp +If the pipeline is not in the background (discussed later), the shell +waits for all commands to complete. +.Pp +If the +.Em pipefail +option was enabled when the shell began execution of the pipeline, the +pipeline's exit status is the exit status of the last command specified in +the pipeline that exited with non-zero status, or zero if all commands in +the pipeline exited with a status of zero. If the +.Em pipefail +option was not enabled, the pipeline's exit status is the exit status of +the last command specified in the pipeline; the exit statuses of any other +commands are not used. If the reserved word ! precedes the pipeline, its +exit status is the logical NOT of the exit status described above. +.Pp +Because pipeline assignment of standard input or standard output or both +takes place before redirection, it can be modified by redirection. +For example: +.Pp +.Dl $ command1 2\*[Gt]&1 | command2 +.Pp +sends both the standard output and standard error of command1 +to the standard input of command2. +.Pp +A ; or +.Aq newline +terminator causes the preceding AND-OR-list (described +next) to be executed sequentially; a & causes asynchronous execution of +the preceding AND-OR-list. +.Pp +Note that unlike some other shells, each process in the pipeline is a +child of the invoking shell (unless it is a shell builtin, in which case +it executes in the current shell \(en but any effect it has on the +environment is wiped). +.Ss Background Commands \(en & +If a command is terminated by the control operator ampersand (&), the +shell executes the command asynchronously \(en that is, the shell does not +wait for the command to finish before executing the next command. +.Pp +The format for running a command in background is: +.Pp +.Dl command1 & [command2 & ...] +.Pp +If the shell is not interactive, the standard input of an asynchronous +command is set to +.Pa /dev/null . +.Ss Lists \(en Generally Speaking +A list is a sequence of zero or more commands separated by newlines, +semicolons, or ampersands, and optionally terminated by one of these three +characters. +The commands in a list are executed in the order they are written. +If command is followed by an ampersand, the shell starts the +command and immediately proceeds onto the next command; otherwise it waits +for the command to terminate before proceeding to the next one. +.Ss Short-Circuit List Operators +.Dq && +and +.Dq || +are AND-OR list operators. +.Dq && +executes the first command, and then executes the second command if and only +if the exit status of the first command is zero. +.Dq || +is similar, but executes the second command if and only if the exit status +of the first command is nonzero. +.Dq && +and +.Dq || +both have the same priority. +.Ss Flow-Control Constructs \(en if, while, for, case +The syntax of the if command is +.Bd -literal -offset indent +if list +then list +[ elif list +then list ] ... +[ else list ] +fi +.Ed +.Pp +The syntax of the while command is +.Bd -literal -offset indent +while list +do list +done +.Ed +.Pp +The two lists are executed repeatedly while the exit status of the +first list is zero. +The until command is similar, but has the word +until in place of while, which causes it to +repeat until the exit status of the first list is zero. +.Pp +The syntax of the for command is +.Bd -literal -offset indent +for variable [ in [ word ... ] ] +do list +done +.Ed +.Pp +The words following +.Pa in +are expanded, and then the list is executed repeatedly with the +variable set to each word in turn. +Omitting in word ... is equivalent to in "$@". +.Pp +The syntax of the break and continue command is +.Bd -literal -offset indent +break [ num ] +continue [ num ] +.Ed +.Pp +Break terminates the num innermost for or while loops. +Continue continues with the next iteration of the innermost loop. +These are implemented as builtin commands. +.Pp +The syntax of the case command is +.Bd -literal -offset indent +case word in +[(]pattern) list ;; +\&... +esac +.Ed +.Pp +The pattern can actually be one or more patterns (see +.Sx Shell Patterns +described later), separated by +.Dq \*(Ba +characters. +The +.Do +( +.Dc +character before the pattern is optional. +.Ss Grouping Commands Together +Commands may be grouped by writing either +.Pp +.Dl (list) +.Pp +or +.Pp +.Dl { list; } +.Pp +The first of these executes the commands in a subshell. +Builtin commands grouped into a (list) will not affect the current shell. +The second form does not fork another shell so is slightly more efficient. +Grouping commands together this way allows you to redirect +their output as though they were one program: +.\".Pp +.Bd -literal -offset indent +{ printf \*q hello \*q ; printf \*q world\\n" ; } \*[Gt] greeting +.Ed +.Pp +Note that +.Dq } +must follow a control operator (here, +.Dq \&; ) +so that it is recognized as a reserved word and not as another command argument. +.Ss Functions +The syntax of a function definition is +.Pp +.Dl name ( ) command +.Pp +A function definition is an executable statement; when executed it +installs a function named name and returns an exit status of zero. +The command is normally a list enclosed between +.Dq { +and +.Dq } . +.Pp +Variables may be declared to be local to a function by using a local +command. +This should appear as the first statement of a function, and the syntax is +.Pp +.Dl local [ variable | - ] ... +.Pp +Local is implemented as a builtin command. +.Pp +When a variable is made local, it inherits the initial value and exported +and readonly flags from the variable with the same name in the surrounding +scope, if there is one. +Otherwise, the variable is initially unset. +The shell uses dynamic scoping, so that if you make the variable x local to +function f, which then calls function g, references to the variable x made +inside g will refer to the variable x declared inside f, not to the global +variable named x. +.Pp +The only special parameter that can be made local is +.Dq - . +Making +.Dq - +local any shell options that are changed via the set command inside the +function to be restored to their original values when the function +returns. +.Pp +The syntax of the return command is +.Pp +.Dl return [ exitstatus ] +.Pp +It terminates the currently executing function. +Return is implemented as a builtin command. +.Ss Variables and Parameters +The shell maintains a set of parameters. +A parameter denoted by a name is called a variable. +When starting up, the shell turns all the environment +variables into shell variables. +New variables can be set using the form +.Pp +.Dl name=value +.Pp +Variables set by the user must have a name consisting solely of +alphabetics, numerics, and underscores - the first of which must not be +numeric. +A parameter can also be denoted by a number or a special +character as explained below. +.Ss Positional Parameters +A positional parameter is a parameter denoted by a number (n \*[Gt] 0). +The shell sets these initially to the values of its command line arguments +that follow the name of the shell script. +The +.Ic set +builtin can also be used to set or reset them. +.Ss Special Parameters +A special parameter is a parameter denoted by one of the following special +characters. +The value of the parameter is listed next to its character. +.Bl -tag -width thinhyphena +.It * +Expands to the positional parameters, starting from one. +When the +expansion occurs within a double-quoted string it expands to a single +field with the value of each parameter separated by the first character of +the +.Ev IFS +variable, or by a +.Aq space +if +.Ev IFS +is unset. +.It @ +Expands to the positional parameters, starting from one. +When the expansion occurs within double-quotes, each positional +parameter expands as a separate argument. +If there are no positional parameters, the +expansion of @ generates zero arguments, even when @ is +double-quoted. +What this basically means, for example, is +if $1 is +.Dq abc +and $2 is +.Dq def ghi , +then +.Qq $@ +expands to +the two arguments: +.Pp +.Sm off +.Dl \*q abc \*q \ \*q def\ ghi \*q +.Sm on +.It # +Expands to the number of positional parameters. +.It ? +Expands to the exit status of the most recent pipeline. +.It - (Hyphen.) +Expands to the current option flags (the single-letter +option names concatenated into a string) as specified on +invocation, by the set builtin command, or implicitly +by the shell. +.It $ +Expands to the process ID of the invoked shell. +A subshell retains the same value of $ as its parent. +.It ! +Expands to the process ID of the most recent background +command executed from the current shell. +For a pipeline, the process ID is that of the last command in the pipeline. +.It 0 (Zero.) +Expands to the name of the shell or shell script. +.El +.Ss Word Expansions +This clause describes the various expansions that are performed on words. +Not all expansions are performed on every word, as explained later. +.Pp +Tilde expansions, parameter expansions, command substitutions, arithmetic +expansions, and quote removals that occur within a single word expand to a +single field. +It is only field splitting or pathname expansion that can +create multiple fields from a single word. +The single exception to this +rule is the expansion of the special parameter @ within double-quotes, as +was described above. +.Pp +The order of word expansion is: +.Bl -enum +.It +Tilde Expansion, Parameter Expansion, Command Substitution, +Arithmetic Expansion (these all occur at the same time). +.It +Field Splitting is performed on fields +generated by step (1) unless the +.Ev IFS +variable is null. +.It +Pathname Expansion (unless set +.Fl f +is in effect). +.It +Quote Removal. +.El +.Pp +The $ character is used to introduce parameter expansion, command +substitution, or arithmetic evaluation. +.Ss Tilde Expansion (substituting a user's home directory) +A word beginning with an unquoted tilde character (~) is +subjected to tilde expansion. +All the characters up to +a slash (/) or the end of the word are treated as a username +and are replaced with the user's home directory. +If the username is missing (as in +.Pa ~/foobar ) , +the tilde is replaced with the value of the +.Va HOME +variable (the current user's home directory). +.Ss Parameter Expansion +The format for parameter expansion is as follows: +.Pp +.Dl ${expression} +.Pp +where expression consists of all characters until the matching +.Dq } . +Any +.Dq } +escaped by a backslash or within a quoted string, and characters in +embedded arithmetic expansions, command substitutions, and variable +expansions, are not examined in determining the matching +.Dq } . +.Pp +The simplest form for parameter expansion is: +.Pp +.Dl ${parameter} +.Pp +The value, if any, of parameter is substituted. +.Pp +The parameter name or symbol can be enclosed in braces, which are +optional except for positional parameters with more than one digit or +when parameter is followed by a character that could be interpreted as +part of the name. +If a parameter expansion occurs inside double-quotes: +.Bl -enum +.It +Pathname expansion is not performed on the results of the expansion. +.It +Field splitting is not performed on the results of the +expansion, with the exception of @. +.El +.Pp +In addition, a parameter expansion can be modified by using one of the +following formats. +.Bl -tag -width aaparameterwordaaaaa +.It ${parameter:-word} +Use Default Values. +If parameter is unset or null, the expansion of word +is substituted; otherwise, the value of parameter is substituted. +.It ${parameter:=word} +Assign Default Values. +If parameter is unset or null, the expansion of +word is assigned to parameter. +In all cases, the final value of parameter is substituted. +Only variables, not positional parameters or special +parameters, can be assigned in this way. +.It ${parameter:?[word]} +Indicate Error if Null or Unset. +If parameter is unset or null, the +expansion of word (or a message indicating it is unset if word is omitted) +is written to standard error and the shell exits with a nonzero exit status. +Otherwise, the value of parameter is substituted. +An interactive shell need not exit. +.It ${parameter:+word} +Use Alternative Value. +If parameter is unset or null, null is +substituted; otherwise, the expansion of word is substituted. +.El +.Pp +In the parameter expansions shown previously, use of the colon in the +format results in a test for a parameter that is unset or null; omission +of the colon results in a test for a parameter that is only unset. +.Bl -tag -width aaparameterwordaaaaa +.It ${#parameter} +String Length. +The length in characters of the value of parameter. +.El +.Pp +The following four varieties of parameter expansion provide for substring +processing. +In each case, pattern matching notation (see +.Sx Shell Patterns ) , +rather than regular expression notation, is used to evaluate the patterns. +If parameter is * or @, the result of the expansion is unspecified. +Enclosing the full parameter expansion string in double-quotes does not +cause the following four varieties of pattern characters to be quoted, +whereas quoting characters within the braces has this effect. +.Bl -tag -width aaparameterwordaaaaa +.It ${parameter%word} +Remove Smallest Suffix Pattern. +The word is expanded to produce a pattern. +The parameter expansion then results in parameter, with the +smallest portion of the suffix matched by the pattern deleted. +.It ${parameter%%word} +Remove Largest Suffix Pattern. +The word is expanded to produce a pattern. +The parameter expansion then results in parameter, with the largest +portion of the suffix matched by the pattern deleted. +.It ${parameter#word} +Remove Smallest Prefix Pattern. +The word is expanded to produce a pattern. +The parameter expansion then results in parameter, with the +smallest portion of the prefix matched by the pattern deleted. +.It ${parameter##word} +Remove Largest Prefix Pattern. +The word is expanded to produce a pattern. +The parameter expansion then results in parameter, with the largest +portion of the prefix matched by the pattern deleted. +.El +.Ss Command Substitution +Command substitution allows the output of a command to be substituted in +place of the command name itself. +Command substitution occurs when the command is enclosed as follows: +.Pp +.Dl $(command) +.Pp +or +.Po +.Dq backquoted +version +.Pc : +.Pp +.Dl `command` +.Pp +The shell expands the command substitution by executing command in a +subshell environment and replacing the command substitution with the +standard output of the command, removing sequences of one or more +.Ao newline Ac Ns s +at the end of the substitution. +(Embedded +.Ao newline Ac Ns s +before +the end of the output are not removed; however, during field splitting, +they may be translated into +.Ao space Ac Ns s , +depending on the value of +.Ev IFS +and quoting that is in effect.) +.Ss Arithmetic Expansion +Arithmetic expansion provides a mechanism for evaluating an arithmetic +expression and substituting its value. +The format for arithmetic expansion is as follows: +.Pp +.Dl $((expression)) +.Pp +The expression is treated as if it were in double-quotes, except +that a double-quote inside the expression is not treated specially. +The shell expands all tokens in the expression for parameter expansion, +command substitution, and quote removal. +.Pp +Next, the shell treats this as an arithmetic expression and +substitutes the value of the expression. +.Ss White Space Splitting (Field Splitting) +After parameter expansion, command substitution, and +arithmetic expansion the shell scans the results of +expansions and substitutions that did not occur in double-quotes for +field splitting and multiple fields can result. +.Pp +The shell treats each character of the +.Ev IFS +as a delimiter and uses the delimiters to split the results of parameter +expansion and command substitution into fields. +.Pp +If +.Ev IFS +is empty, field splitting yields no fields if the input string was empty, +and one string with the unchanged value of the input otherwise. +For example, with the default +.Ev IFS , +.Dq Ic read Fl r Ev l +will remove any initial whitespace, +but +.Dq Ev IFS Ns = Ic read Fl r Ev l +will leave the entire line in +.Ev l . +.Ss Pathname Expansion (File Name Generation) +Unless the +.Fl f +flag is set, file name generation is performed after word splitting is +complete. +Each word is viewed as a series of patterns, separated by slashes. +The process of expansion replaces the word with the names of all +existing files whose names can be formed by replacing each pattern with a +string that matches the specified pattern. +There are two restrictions on +this: first, a pattern cannot match a string containing a slash, and +second, a pattern cannot match a string starting with a period unless the +first character of the pattern is a period. +The next section describes the +patterns used for both Pathname Expansion and the +.Ic case +command. +.Ss Shell Patterns +A pattern consists of normal characters, which match themselves, +and meta-characters. +The meta-characters are +.Dq \&! , +.Dq * , +.Dq \&? , +and +.Dq \&[ . +These characters lose their special meanings if they are quoted. +When command or variable substitution is performed +and the dollar sign or back quotes are not double quoted, +the value of the variable or the output of +the command is scanned for these characters and they are turned into +meta-characters. +.Pp +An asterisk +.Pq Dq * +matches any string of characters. +A question mark matches any single character. +A left bracket +.Pq Dq \&[ +introduces a character class. +The end of the character class is indicated by a +.Pq Dq \&] ; +if the +.Dq \&] +is missing then the +.Dq \&[ +matches a +.Dq \&[ +rather than introducing a character class. +A character class matches any of the characters between the square brackets. +A range of characters may be specified using a minus sign. +The character class may be complemented +by making an exclamation point the first character of the character class. +.Pp +To include a +.Dq \&] +in a character class, make it the first character listed (after the +.Dq \&! , +if any). +To include a minus sign, make it the first or last character listed. +.Ss Builtins +This section lists the builtin commands which are builtin because they +need to perform some operation that can't be performed by a separate +process. +In addition to these, there are several other commands that may +be builtin for efficiency (e.g. +.Xr printf 1 , +.Xr echo 1 , +.Xr test 1 , +etc). +.Bl -tag -width 5n +.It : +.It true +A null command that returns a 0 (true) exit value. +.It false +A null command that returns a 1 (false) exit value. +.It \&. file +The commands in the specified file are read and executed by the shell. +.It alias Op Ar name Ns Op Ar "=string ..." +If +.Ar name=string +is specified, the shell defines the alias +.Ar name +with value +.Ar string . +If just +.Ar name +is specified, the value of the alias +.Ar name +is printed. +With no arguments, the +.Ic alias +builtin prints the +names and values of all defined aliases (see +.Ic unalias ) . +.It bg [ Ar job ] ... +Continue the specified jobs (or the current job if no +jobs are given) in the background. +.It Xo command +.Op Fl p +.Op Fl v +.Op Fl V +.Ar command +.Op Ar arg ... +.Xc +Execute the specified command but ignore shell functions when searching +for it. +(This is

directory +.Xc +Switch to the specified directory (default +.Ev HOME ) . +If an entry for +.Ev CDPATH +appears in the environment of the +.Ic cd +command or the shell variable +.Ev CDPATH +is set and the directory name does not begin with a slash, then the +directories listed in +.Ev CDPATH +will be searched for the specified directory. +The format of +.Ev CDPATH +is the same as that of +.Ev PATH . +If a single dash is specified as the argument, it will be replaced by the +value of +.Ev OLDPWD . +The +.Ic cd +command will print out the name of the +directory that it actually switched to if this is different from the name +that the user gave. +These may be different either because the +.Ev CDPATH +mechanism was used or because the argument is a single dash. +The +.Fl P +option causes the physical directory structure to be used, that is, all +symbolic links are resolved to their respective values. +The +.Fl L +option turns off the effect of any preceding +.Fl P +options. +.It Xo echo Op Fl n +.Ar args... +.Xc +Print the arguments on the standard output, separated by spaces. +Unless the +.Fl n +option is present, a newline is output following the arguments. +.Pp +If any of the following sequences of characters is encountered during +output, the sequence is not output. +Instead, the specified action is +performed: +.Bl -tag -width indent +.It Li \eb +A backspace character is output. +.It Li \ec +Subsequent output is suppressed. +This is normally used at the end of the +last argument to suppress the trailing newline that +.Ic echo +would otherwise output. +.It Li \ef

backslash sequences elicit undefined behaviour. +.It eval Ar string ... +Concatenate all the arguments with spaces. +Then re-parse and execute the command. +.It exec Op Ar command arg ... +Unless command is omitted, the shell process is replaced with the +specified program (which must be a real program, not a shell builtin or +function). +Any redirections on the +.Ic exec +command are marked as permanent, so that they are not undone when the +.Ic exec +command finishes. +.It exit Op Ar exitstatus +Terminate the shell process. +If +.Ar exitstatus +is given it is used as the exit status of the shell; otherwise the +exit status of the preceding command is used. +.It export Ar name ... +.It export Fl p +The specified names are exported so that they will appear in the +environment of subsequent commands. +The only way to un-export a variable is to unset it. +The shell allows the value of a variable to be set at the +same time it is exported by writing +.Pp +.Dl export name=value +.Pp +With no arguments the export command lists the names of all exported variables. +With the +.Fl p +option specified the output will be formatted suitably for non-interactive use. +.It Xo fc Op Fl

fg Op Ar job +Move the specified job or the current job to the foreground. +.It getopts Ar optstring var Op Ar arg ... +The +.Tn POSIX +.Ic getopts +command, not to be confused with the +.Em Bell Labs Ns -derived +.Xr getopt 1 . +.Pp +The first argument should be a series of letters, each of which may be +optionally followed by a colon to indicate that the option requires an +argument. +The variable specified is set to the parsed option. +.Pp +The +.Ic getopts +command deprecates the older +.Xr getopt 1 +utility due to its handling of arguments containing whitespace. +.Pp +The +.Ic getopts +builtin may be used to obtain options and their arguments +from a list of parameters. +When invoked, +.Ic getopts +places the value of the next option from the option string in the list in +the shell variable specified by +.Va var +and its index in the shell variable +.Ev OPTIND . +When the shell is invoked, +.Ev OPTIND +is initialized to 1. +For each option that requires an argument, the +.Ic getopts +builtin will place it in the shell variable +.Ev OPTARG . +If an option is not allowed for in the +.Va optstring , +then +.Ev OPTARG +will be unset. +.Pp +By default, the variables +.Va $1 , ... , $n +are inspected; if +.Ar arg Ns s +are specified, they'll be parsed instead. +.Pp +.Va optstring +is a string of recognized option letters (see +.Xr getopt 3 ) . +If a letter is followed by a colon, the option is expected to have an +argument which may or may not be separated from it by white space. +If an option character is not found where expected, +.Ic getopts +will set the variable +.Va var +to a +.Dq \&? ; +.Ic getopts +will then unset +.Ev OPTARG +and write output to standard error. +By specifying a colon as the first character of +.Va optstring +all errors will be ignored. +.Pp +After the last option +.Ic getopts +will return a non-zero value and set +.Va var +to +.Dq \&? . +.Pp +The following code fragment shows how one might process the arguments +for a

remembers the +locations of commands. +With no arguments whatsoever, +the +.Ic hash +command prints out the contents of this table. +Entries which have not been looked at since the last +.Ic cd +command are marked with an asterisk; it is possible for these entries +to be invalid. +.Pp +With arguments, the +.Ic hash +command removes the specified commands from the hash table (unless +they are functions) and then locates them. +The +.Fl r +option causes the hash command to delete all the entries in the hash table +except for functions. +.It jobs Oo Fl lp Oc Op Ar job ... +Display the status of all, or just the specified, +.Ar job Ns s : +.Bl -tag -compact -offset 5n -width "By default" +.It By default +display the job number, currency +.Pq Sy +- +status, if any, the job state, and its

command remembers what the current directory +is rather than recomputing it each time. +This makes it faster. +However, if the current directory is renamed, the builtin version of +.Ic pwd +will continue to print the old name for the directory. +The +.Fl P +option causes the physical value of the current working directory to be shown, +that is, all symbolic links are resolved to their respective values. +The +.Fl L +option turns off the effect of any preceding +.Fl P +options. +.It Xo read Op Fl p Ar prompt +.Op Fl r +.Ar variable +.Op Ar ... +.Xc +The prompt is printed if the +.Fl p +option is specified and the standard input is a terminal. +Then a line is read from the standard input. +The trailing newline is deleted from the +line and the line is split as described in the section on word splitting +above, and the pieces are assigned to the variables in order. +At least one variable must be specified. +If there are more pieces than variables, the remaining pieces +(along with the characters in +.Ev IFS +that separated them) are assigned to the last variable. +If there are more variables than pieces, +the remaining variables are assigned the null string. +The +.Ic read +builtin will indicate success unless EOF is encountered on input, in +which case failure is returned. +.Pp +By default, unless the +.Fl r +option is specified, the backslash +.Dq \e +acts as an escape character, causing the following character to be treated +literally. +If a backslash is followed by a newline, the backslash and the +newline will be deleted. +.It readonly Ar name ...

string which contains three types of objects: plain characters, +which are simply copied to standard output, character escape sequences which +are converted and copied to the standard output, and format specifications, +each of which causes printing of the next successive +.Ar value . +.Pp +Each +.Ar value +is treated as a string if the corresponding format specification is +either +.Cm b , +.Cm c , +or +.Cm s ; +otherwise it is evaluated as a C constant, with the following additions: +.Bl -bullet -offset indent -compact +.It +A leading plus or minus sign is allowed. +.It +If the leading

result has the string +.Li 0x +.Pq Li 0X +prepended to it. +For +.Cm e , +.Cm E , +.Cm f , +.Cm g , +and +.Cm G +formats, the result will always contain a decimal point, even if no +digits follow the

If file + * access permissions deny access, the requested operation shall fail. + * + * and of course access permissions are described as one might expect: + * + * * If a process has the appropriate privilege: + * + * * If read, write, or directory search permission is requested, + * access shall be granted. + * + * * If execute permission is requested, access shall be granted if + * execute permission is granted to at least one user by the file + * permission bits or by an alternate access control mechanism; + * otherwise, access shall be denied. + * + * * Otherwise: + * + * * The file permission bits of a file contain read, write, and + * execute/search permissions for the file owner class, file group + * class, and file other class. + * + * * Access shall be granted if an alternate access control mechanism + * is not enabled and the requested access permission bit is set for + * the class (file owner class, file group class, or file other class) + * to which the process belongs, or if an alternate access control + * mechanism is enabled and it allows the requested access; otherwise, + * access shall be denied. + * + * and when I first read this I thought: surely we can't go about using + * open(O_WRONLY) to try this test! However the POSIX 1003.1-2001 Rationale + * section for test does in fact say: + * + * On historical BSD systems, test -w directory always returned false + * because test tried to open the directory for writing, which always + * fails. + * + * and indeed this is in fact true for Seventh Edition UNIX, UNIX 32V, and UNIX + * System III, and thus presumably also for BSD up to and including 4.3. + * + * Secondly I remembered why using open() and/or access() are bogus. They + * don't work right for detecting read and write permissions bits when called + * by root. + * + * Interestingly the 'test' in 4.4BSD was closer to correct (as per + * 1003.2-1992) and it was implemented efficiently with stat() instead of + * open(). + * + * This was apparently broken in NetBSD around about 1994/06/30 when the old + * 4.4BSD implementation was replaced with a (arguably much better coded) + * implementation derived from pdksh. + * + * Note that modern pdksh is yet different again, but still not correct, at + * least not w.r.t. 1003.2-1992. + * + * As I think more about it and read more of the related IEEE docs I don't like + * that wording about 'test -r' and 'test -w' in 1003.1-2001 at all. I very + * much prefer the original wording in 1003.2-1992. It is much more useful, + * and so that's what I've implemented. + * + * (Note that a strictly conforming implementation of 1003.1-2001 is in fact + * totally useless for the case in question since its 'test -w' and 'test -r' + * can never fail for root for any existing files, i.e. files for which 'test + * -e' succeeds.) + * + * The rationale for 1003.1-2001 suggests that the wording was "clarified" in + * 1003.1-2001 to align with the 1003.2b draft. 1003.2b Draft 12 (July 1999), + * which is the latest copy I have, does carry the same suggested wording as is + * in 1003.1-2001, with its rationale saying: + * + * This change is a clarification and is the result of interpretation + * request PASC 1003.2-92 #23 submitted for IEEE Std 1003.2-1992. + * + * That interpretation can be found here: + * + * http://www.pasc.org/interps/unofficial/db/p1003.2/pasc-1003.2-23.html + * + * Not terribly helpful, unfortunately. I wonder who that fence sitter was. + * + * Worse, IMVNSHO, I think the authors of 1003.2b-D12 have mis-interpreted the + * PASC interpretation and appear to be gone against at least one widely used + * implementation (namely 4.4BSD). The problem is that for file access by root + * this means that if test '-r' and '-w' are to behave as if open() were called + * then there's no way for a shell script running as root to check if a file + * has certain access bits set other than by the grotty means of interpreting + * the output of 'ls -l'. This was widely considered to be a bug in V7's + * "test" and is, I believe, one of the reasons why direct use of access() was + * avoided in some more recent implementations! + * + * I have always interpreted '-r' to match '-w' and '-x' as per the original + * wording in 1003.2-1992, not the other way around. I think 1003.2b goes much + * too far the wrong way without any valid rationale and that it's best if we + * stick with 1003.2-1992 and test the flags, and not mimic the behaviour of + * open() since we already know very well how it will work -- existance of the + * file is all that matters to open() for root. + * + * Unfortunately the SVID is no help at all (which is, I guess, partly why + * we're in this mess in the first place :-). + * + * The SysV implementation (at least in the 'test' builtin in /bin/sh) does use + * access(name, 2) even though it also goes to much greater lengths for '-x' + * matching the 1003.2-1992 definition (which is no doubt where that definition + * came from). + * + * The ksh93 implementation uses access() for '-r' and '-w' if + * (euid==uid&&egid==gid), but uses st_mode for '-x' iff running as root. + * i.e. it does strictly conform to 1003.1-2001 (and presumably 1003.2b). + */ +int test_access(const struct stat64 *sp, int stmode) +{ + gid_t *groups;

This is very fast because it provides good assurance +// that the mutex on each heap will be uncontended.

Introduction +=============== +miniaudio is a single file library for audio playback and capture. To use it, do the following in +one .c file: + + ```c + #define MINIAUDIO_IMPLEMENTATION + #include "miniaudio.h" + ``` + +You can do `#include "miniaudio.h"` in other parts of the program just like any other header. + +miniaudio includes both low level and high level APIs. The low level API is good for those who want +to do all of their mixing themselves and only require a light weight interface to the underlying +audio device. The high level API is good for those who have complex mixing and effect requirements. + +In miniaudio, objects are transparent structures. Unlike many other libraries, there are no handles +to opaque objects which means you need to allocate memory for objects yourself. In the examples +presented in this documentation you will often see objects declared on the stack. You need to be +careful when translating these examples to your own code so that you don't accidentally declare +your objects on the stack and then cause them to become invalid once the function returns. In +addition, you must ensure the memory address of your objects remain the same throughout their +lifetime. You therefore cannot be making copies of your objects. + +A config/init pattern is used throughout the entire library. The idea is that you set up a config +object and pass that into the initialization routine. The advantage to this system is that the +config object can be initialized with logical defaults and new properties added to it without +breaking the API. The config object can be allocated on the stack and does not need to be +maintained after initialization of the corresponding object. + + +1.1. Low Level API +------------------ +The low level API gives you access to the raw audio data of an audio device. It supports playback, +capture, full-duplex and loopback (WASAPI only). You can enumerate over devices to determine which +physical device(s) you want to connect to. + +The low level API uses the concept of a "device" as the abstraction for physical devices. The idea +is that you choose a physical device to emit or capture audio from, and then move data to/from the +device when miniaudio tells you to. Data is delivered to and from devices asynchronously via a +callback which you specify when initializing the device. + +When initializing the device you first need to configure it. The device configuration allows you to +specify things like the format of the data delivered via the callback, the size of the internal +buffer and the ID of the device you want to emit or capture audio from. + +Once you have the device configuration set up you can initialize the device. When initializing a +device you need to allocate memory for the device object beforehand. This gives the application +complete control over how the memory is allocated. In the example below we initialize a playback +device on the stack, but you could allocate it on the heap if that suits your situation better. + + ```c + void data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount) + { + // In playback mode copy data to pOutput. In capture mode read data from pInput. In full-duplex mode, both + // pOutput and pInput will be valid and you can move data from pInput into pOutput. Never process more than + // frameCount frames. + } + + int main() + { + ma_device_config config = ma_device_config_init(ma_device_type_playback); + config.playback.format = ma_format_f32; // Set to ma_format_unknown to use the device's native format. + config.playback.channels = 2; // Set to 0 to use the device's native channel count. + config.sampleRate = 48000; // Set to 0 to use the device's native sample rate. + config.dataCallback = data_callback; // This function will be called when miniaudio needs more data. + config.pUserData = pMyCustomData; // Can be accessed from the device object (device.pUserData). + + ma_device device; + if (ma_device_init(NULL, &config, &device) != MA_SUCCESS) { + return -1; // Failed to initialize the device. + } + + ma_device_start(&device); // The device is sleeping by default so you'll need to start it manually. + + // Do something here. Probably your program's main loop. + + ma_device_uninit(&device); + return 0; + } + ``` + +In the example above, `data_callback()` is where audio data is written and read from the device. +The idea is in playback mode you cause sound to be emitted from the speakers by writing audio data +to the output buffer (`pOutput` in the example). In capture mode you read data from the input +buffer (`pInput`) to extract sound captured by the microphone. The `frameCount` parameter tells you +how many frames can be written to the output buffer and read from the input buffer. A "frame" is +one sample for each channel. For example, in a stereo stream (2 channels), one frame is 2 +samples: one for the left, one for the right. The channel count is defined by the device config. +The size in bytes of an individual sample is defined by the sample format which is also specified +in the device config. Multi-channel audio data is always interleaved, which means the samples for +each frame are stored next to each other in memory. For example, in a stereo stream the first pair +of samples will be the left and right samples for the first frame, the second pair of samples will +be the left and right samples for the second frame, etc. + +The configuration of the device is defined by the `ma_device_config` structure. The config object +is always initialized with `ma_device_config_init()`. It's important to always initialize the +config with this function as it initializes it with logical defaults and ensures your program +doesn't break when new members are added to the `ma_device_config` structure. The example above +uses a fairly simple and standard device configuration. The call to `ma_device_config_init()` takes +a single parameter, which is whether or not the device is a playback, capture, duplex or loopback +device (loopback devices are not supported on all backends). The `config.playback.format` member +sets the sample format which can be one of the following (all formats are native-endian): + + +---------------+----------------------------------------+---------------------------+ + | Symbol | Description | Range | + +---------------+----------------------------------------+---------------------------+ + | ma_format_f32 | 32-bit floating point | [-1, 1] | + | ma_format_s16 | 16-bit signed integer | [-32768, 32767] | + | ma_format_s24 | 24-bit signed integer (tightly packed) | [-8388608, 8388607] | + | ma_format_s32 | 32-bit signed integer | [-2147483648, 2147483647] | + | ma_format_u8 | 8-bit unsigned integer | [0, 255] | + +---------------+----------------------------------------+---------------------------+ + +The `config.playback.channels` member sets the number of channels to use with the device. The +channel count cannot exceed MA_MAX_CHANNELS. The `config.sampleRate` member sets the sample rate +(which must be the same for both playback and capture in full-duplex configurations). This is +usually set to 44100 or 48000, but can be set to anything. It's recommended to keep this between +8000 and 384000, however. + +Note that leaving the format, channel count and/or sample rate at their default values will result +in the internal device's native configuration being used which is useful if you want to avoid the +overhead of miniaudio's automatic data conversion. + +In addition to the sample format, channel count and sample rate, the data callback and user data +pointer are also set via the config. The user data pointer is not passed into the callback as a +parameter, but is instead set to the `pUserData` member of `ma_device` which you can access +directly since all miniaudio structures are transparent. + +Initializing the device is done with `ma_device_init()`. This will return a result code telling you +what went wrong, if anything. On success it will return `MA_SUCCESS`. After initialization is +complete the device will be in a stopped state. To start it, use `ma_device_start()`. +Uninitializing the device will stop it, which is what the example above does, but you can also stop +the device with `ma_device_stop()`. To resume the device simply call `ma_device_start()` again. +Note that it's important to never stop or start the device from inside the callback. This will +result in a deadlock. Instead you set a variable or signal an event indicating that the device +needs to stop and handle it in a different thread. The following APIs must never be called inside +the callback: + + ```c + ma_device_init() + ma_device_init_ex() + ma_device_uninit() + ma_device_start() + ma_device_stop() + ``` + +You must never try uninitializing and reinitializing a device inside the callback. You must also +never try to stop and start it from inside the callback. There are a few other things you shouldn't +do in the callback depending on your requirements, however this isn't so much a thread-safety +thing, but rather a real-time processing thing which is beyond the scope of this introduction. + +The example above demonstrates the initialization of a playback device, but it works exactly the +same for capture. All you need to do is change the device type from `ma_device_type_playback` to +`ma_device_type_capture` when setting up the config, like so: + + ```c + ma_device_config config = ma_device_config_init(ma_device_type_capture); + config.capture.format = MY_FORMAT; + config.capture.channels = MY_CHANNEL_COUNT; + ``` + +In the data callback you just read from the input buffer (`pInput` in the example above) and leave +the output buffer alone (it will be set to NULL when the device type is set to +`ma_device_type_capture`). + +These are the available device types and how you should handle the buffers in the callback: + + +-------------------------+--------------------------------------------------------+ + | Device Type | Callback Behavior | + +-------------------------+--------------------------------------------------------+ + | ma_device_type_playback | Write to output buffer, leave input buffer untouched. | + | ma_device_type_capture | Read from input buffer, leave output buffer untouched. | + | ma_device_type_duplex | Read from input buffer, write to output buffer. | + | ma_device_type_loopback | Read from input buffer, leave output buffer untouched. | + +-------------------------+--------------------------------------------------------+ + +You will notice in the example above that the sample format and channel count is specified +separately for playback and capture. This is to support different data formats between the playback +and capture devices in a full-duplex system. An example may be that you want to capture audio data +as a monaural stream (one channel), but output sound to a stereo speaker system. Note that if you +use different formats between playback and capture in a full-duplex configuration you will need to +convert the data yourself. There are functions available to help you do this which will be +explained later. + +The example above did not specify a physical device to connect to which means it will use the +operating system's default device. If you have multiple physical devices connected and you want to +use a specific one you will need to specify the device ID in the configuration, like so: + + ```c + config.playback.pDeviceID = pMyPlaybackDeviceID; // Only if requesting a playback or duplex device. + config.capture.pDeviceID = pMyCaptureDeviceID; // Only if requesting a capture, duplex or loopback device. + ``` + +To retrieve the device ID you will need to perform device enumeration, however this requires the +use of a new concept called the "context". Conceptually speaking the context sits above the device. +There is one context to many devices. The purpose of the context is to represent the backend at a +more global level and to perform operations outside the scope of an individual device. Mainly it is +used for performing run-time linking against backend libraries, initializing backends and +enumerating devices. The example below shows how to enumerate devices. + + ```c + ma_context context; + if (ma_context_init(NULL, 0, NULL, &context) != MA_SUCCESS) { + // Error. + } + + ma_device_info* pPlaybackInfos; + ma_uint32 playbackCount; + ma_device_info* pCaptureInfos; + ma_uint32 captureCount; + if (ma_context_get_devices(&context, &pPlaybackInfos, &playbackCount, &pCaptureInfos, &captureCount) != MA_SUCCESS) { + // Error. + } + + // Loop over each device info and do something with it. Here we just print the name with their index. You may want + // to give the user the opportunity to choose which device they'd prefer. + for (ma_uint32 iDevice = 0; iDevice < playbackCount; iDevice += 1) { + printf("%d - %s\n", iDevice, pPlaybackInfos[iDevice].name); + } + + ma_device_config config = ma_device_config_init(ma_device_type_playback); + config.playback.pDeviceID = &pPlaybackInfos[chosenPlaybackDeviceIndex].id; + config.playback.format = MY_FORMAT; + config.playback.channels = MY_CHANNEL_COUNT; + config.sampleRate = MY_SAMPLE_RATE; + config.dataCallback = data_callback; + config.pUserData = pMyCustomData; + + ma_device device; + if (ma_device_init(&context, &config, &device) != MA_SUCCESS) { + // Error + } + + ... + + ma_device_uninit(&device); + ma_context_uninit(&context); + ``` + +The first thing we do in this example is initialize a `ma_context` object with `ma_context_init()`. +The first parameter is a pointer to a list of `ma_backend` values which are used to override the +default backend priorities. When this is NULL, as in this example, miniaudio's default priorities +are used. The second parameter is the number of backends listed in the array pointed to by the +first parameter. The third parameter is a pointer to a `ma_context_config` object which can be +NULL, in which case defaults are used. The context configuration is used for setting the logging +callback, custom memory allocation callbacks, user-defined data and some backend-specific +configurations. + +Once the context has been initialized you can enumerate devices. In the example above we use the +simpler `ma_context_get_devices()`, however you can also use a callback for handling devices by +using `ma_context_enumerate_devices()`. When using `ma_context_get_devices()` you provide a pointer +to a pointer that will, upon output, be set to a pointer to a buffer containing a list of +`ma_device_info` structures. You also provide a pointer to an unsigned integer that will receive +the number of items in the returned buffer. Do not free the returned buffers as their memory is +managed internally by miniaudio. + +The `ma_device_info` structure contains an `id` member which is the ID you pass to the device +config. It also contains the name of the device which is useful for presenting a list of devices +to the user via the UI. + +When creating your own context you will want to pass it to `ma_device_init()` when initializing the +device. Passing in NULL, like we do in the first example, will result in miniaudio creating the +context for you, which you don't want to do since you've already created a context. Note that +internally the context is only tracked by it's pointer which means you must not change the location +of the `ma_context` object. If this is an issue, consider using `malloc()` to allocate memory for +the context. + + +1.2. High Level API +------------------- +The high level API consists of three main parts: + + * Resource management for loading and streaming sounds. + * A node graph for advanced mixing and effect processing. + * A high level "engine" that wraps around the resource manager and node graph. + +The resource manager (`ma_resource_manager`) is used for loading sounds. It supports loading sounds +fully into memory and also streaming. It will also deal with reference counting for you which +avoids the same sound being loaded multiple times. + +The node graph is used for mixing and effect processing. The idea is that you connect a number of +nodes into the graph by connecting each node's outputs to another node's inputs. Each node can +implement it's own effect. By chaining nodes together, advanced mixing and effect processing can +be achieved. + +The engine encapsulates both the resource manager and the node graph to create a simple, easy to +use high level API. The resource manager and node graph APIs are covered in more later sections of +this manual. + +The code below shows how you can initialize an engine using it's default configuration. + + ```c + ma_result result; + ma_engine engine; + + result = ma_engine_init(NULL, &engine); + if (result != MA_SUCCESS) { + return result; // Failed to initialize the engine. + } + ``` + +This creates an engine instance which will initialize a device internally which you can access with +`ma_engine_get_device()`. It will also initialize a resource manager for you which can be accessed +with `ma_engine_get_resource_manager()`. The engine itself is a node graph (`ma_node_graph`) which +means you can pass a pointer to the engine object into any of the `ma_node_graph` APIs (with a +cast). Alternatively, you can use `ma_engine_get_node_graph()` instead of a cast. + +Note that all objects in miniaudio, including the `ma_engine` object in the example above, are +transparent structures. There are no handles to opaque structures in miniaudio which means you need +to be mindful of how you declare them. In the example above we are declaring it on the stack, but +this will result in the struct being invalidated once the function encapsulating it returns. If +allocating the engine on the heap is more appropriate, you can easily do so with a standard call +to `malloc()` or whatever heap allocation routine you like: + + ```c + ma_engine* pEngine = malloc(sizeof(*pEngine)); + ``` + +The `ma_engine` API uses the same config/init pattern used all throughout miniaudio. To configure +an engine, you can fill out a `ma_engine_config` object and pass it into the first parameter of +`ma_engine_init()`: + + ```c + ma_result result; + ma_engine engine; + ma_engine_config engineConfig; + + engineConfig = ma_engine_config_init(); + engineConfig.pResourceManager = &myCustomResourceManager; // <-- Initialized as some earlier stage. + + result = ma_engine_init(&engineConfig, &engine); + if (result != MA_SUCCESS) { + return result; + } + ``` + +This creates an engine instance using a custom config. In this particular example it's showing how +you can specify a custom resource manager rather than having the engine initialize one internally. +This is particularly useful if you want to have multiple engine's share the same resource manager. + +The engine must be uninitialized with `ma_engine_uninit()` when it's no longer needed. + +By default the engine will be started, but nothing will be playing because no sounds have been +initialized. The easiest but least flexible way of playing a sound is like so: + + ```c + ma_engine_play_sound(&engine, "my_sound.wav", NULL); + ``` + +This plays what miniaudio calls an "inline" sound. It plays the sound once, and then puts the +internal sound up for recycling. The last parameter is used to specify which sound group the sound +should be associated with which will be explained later. This particular way of playing a sound is +simple, but lacks flexibility and features. A more flexible way of playing a sound is to first +initialize a sound: + + ```c + ma_result result; + ma_sound sound; + + result = ma_sound_init_from_file(&engine, "my_sound.wav", 0, NULL, NULL, &sound); + if (result != MA_SUCCESS) { + return result; + } + + ma_sound_start(&sound); + ``` + +This returns a `ma_sound` object which represents a single instance of the specified sound file. If +you want to play the same file multiple times simultaneously, you need to create one sound for each +instance. + +Sounds should be uninitialized with `ma_sound_uninit()`. + +Sounds are not started by default. Start a sound with `ma_sound_start()` and stop it with +`ma_sound_stop()`. When a sound is stopped, it is not rewound to the start. Use +`ma_sound_seek_to_pcm_frame(&sound, 0)` to seek back to the start of a sound. By default, starting +and stopping sounds happens immediately, but sometimes it might be convenient to schedule the sound +the be started and/or stopped at a specific time. This can be done with the following functions: + + ```c + ma_sound_set_start_time_in_pcm_frames() + ma_sound_set_start_time_in_milliseconds() + ma_sound_set_stop_time_in_pcm_frames() + ma_sound_set_stop_time_in_milliseconds() + ``` + +The start/stop time needs to be specified based on the absolute timer which is controlled by the +engine. The current global time time in PCM frames can be retrieved with +`ma_engine_get_time_in_pcm_frames()`. The engine's global time can be changed with +`ma_engine_set_time_in_pcm_frames()` for synchronization purposes if required. Note that scheduling +a start time still requires an explicit call to `ma_sound_start()` before anything will play: + + ```c + ma_sound_set_start_time_in_pcm_frames(&sound, ma_engine_get_time_in_pcm_frames(&engine) + (ma_engine_get_sample_rate(&engine) * 2); + ma_sound_start(&sound); + ``` + +The third parameter of `ma_sound_init_from_file()` is a set of flags that control how the sound be +loaded and a few options on which features should be enabled for that sound. By default, the sound +is synchronously loaded fully into memory straight from the file system without any kind of +decoding. If you want to decode the sound before storing it in memory, you need to specify the +`MA_SOUND_FLAG_DECODE` flag. This is useful if you want to incur the cost of decoding at an earlier +stage, such as a loading stage. Without this option, decoding will happen dynamically at mixing +time which might be too expensive on the audio thread. + +If you want to load the sound asynchronously, you can specify the `MA_SOUND_FLAG_ASYNC` flag. This +will result in `ma_sound_init_from_file()` returning quickly, but the sound will not start playing +until the sound has had some audio decoded. + +The fourth parameter is a pointer to sound group. A sound group is used as a mechanism to organise +sounds into groups which have their own effect processing and volume control. An example is a game +which might have separate groups for sfx, voice and music. Each of these groups have their own +independent volume control. Use `ma_sound_group_init()` or `ma_sound_group_init_ex()` to initialize +a sound group. + +Sounds and sound groups are nodes in the engine's node graph and can be plugged into any `ma_node` +API. This makes it possible to connect sounds and sound groups to effect nodes to produce complex +effect chains. + +A sound can have it's volume changed with `ma_sound_set_volume()`. If you prefer decibel volume +control you can use `ma_volume_db_to_linear()` to convert from decibel representation to linear. + +Panning and pitching is supported with `ma_sound_set_pan()` and `ma_sound_set_pitch()`. If you know +a sound will never have it's pitch changed with `ma_sound_set_pitch()` or via the doppler effect, +you can specify the `MA_SOUND_FLAG_NO_PITCH` flag when initializing the sound for an optimization. + +By default, sounds and sound groups have spatialization enabled. If you don't ever want to +spatialize your sounds, initialize the sound with the `MA_SOUND_FLAG_NO_SPATIALIZATION` flag. The +spatialization model is fairly simple and is roughly on feature parity with OpenAL. HRTF and +environmental occlusion are not currently supported, but planned for the future. The supported +features include: + + * Sound and listener positioning and orientation with cones + * Attenuation models: none, inverse, linear and exponential + * Doppler effect + +Sounds can be faded in and out with `ma_sound_set_fade_in_pcm_frames()`. + +To check if a sound is currently playing, you can use `ma_sound_is_playing()`. To check if a sound +is at the end, use `ma_sound_at_end()`. Looping of a sound can be controlled with +`ma_sound_set_looping()`. Use `ma_sound_is_looping()` to check whether or not the sound is looping. + + + +2. Building +=========== +miniaudio should work cleanly out of the box without the need to download or install any +dependencies. See below for platform-specific details. + +Note that GCC and Clang require `-msse2`, `-mavx2`, etc. for SIMD optimizations. + +If you get errors about undefined references to `__sync_val_compare_and_swap_8`, `__atomic_load_8`, +etc. you need to link with `-latomic`. + + +2.1. Windows +------------ +The Windows build should compile cleanly on all popular compilers without the need to configure any +include paths nor link to any libraries. + +The UWP build may require linking to mmdevapi.lib if you get errors about an unresolved external +symbol for `ActivateAudioInterfaceAsync()`. + + +2.2. macOS and iOS +------------------ +The macOS build should compile cleanly without the need to download any dependencies nor link to +any libraries or frameworks. The iOS build needs to be compiled as Objective-C and will need to +link the relevant frameworks but should compile cleanly out of the box with Xcode. Compiling +through the command line requires linking to `-lpthread` and `-lm`. + +Due to the way miniaudio links to frameworks at runtime, your application may not pass Apple's +notarization process. To fix this there are two options. The first is to use the +`MA_NO_RUNTIME_LINKING` option, like so: + + ```c + #ifdef __APPLE__ + #define MA_NO_RUNTIME_LINKING + #endif + #define MINIAUDIO_IMPLEMENTATION + #include "miniaudio.h" + ``` + +This will require linking with `-framework CoreFoundation -framework CoreAudio -framework AudioToolbox`. +If you get errors about AudioToolbox, try with `-framework AudioUnit` instead. You may get this when +using older versions of iOS. Alternatively, if you would rather keep using runtime linking you can +add the following to your entitlements.xcent file: + + ``` + com.apple.security.cs.allow-dyld-environment-variables + + com.apple.security.cs.allow-unsigned-executable-memory + + ``` + +See this discussion for more info: https://github.com/mackron/miniaudio/issues/203. + + +2.3. Linux +---------- +The Linux build only requires linking to `-ldl`, `-lpthread` and `-lm`. You do not need any +development packages. You may need to link with `-latomic` if you're compiling for 32-bit ARM. + + +2.4. BSD +-------- +The BSD build only requires linking to `-lpthread` and `-lm`. NetBSD uses audio(4), OpenBSD uses +sndio and FreeBSD uses OSS. You may need to link with `-latomic` if you're compiling for 32-bit +ARM. + + +2.5. Android +------------ +AAudio is the highest priority backend on Android. This should work out of the box without needing +any kind of compiler configuration. Support for AAudio starts with Android 8 which means older +versions will fall back to OpenSL|ES which requires API level 16+. + +There have been reports that the OpenSL|ES backend fails to initialize on some Android based +devices due to `dlopen()` failing to open "libOpenSLES.so". If this happens on your platform +you'll need to disable run-time linking with `MA_NO_RUNTIME_LINKING` and link with -lOpenSLES. + + +2.6. Emscripten +--------------- +The Emscripten build emits Web Audio JavaScript directly and should compile cleanly out of the box. +You cannot use `-std=c*` compiler flags, nor `-ansi`. + +You can enable the use of AudioWorkets by defining `MA_ENABLE_AUDIO_WORKLETS` and then compiling +with the following options: + + -sAUDIO_WORKLET=1 -sWASM_WORKERS=1 -sASYNCIFY + +An example for compiling with AudioWorklet support might look like this: + + emcc program.c -o bin/program.html -DMA_ENABLE_AUDIO_WORKLETS -sAUDIO_WORKLET=1 -sWASM_WORKERS=1 -sASYNCIFY + +To run locally, you'll need to use emrun: + + emrun bin/program.html + + + +2.7.

Definitions +============== +This section defines common terms used throughout miniaudio. Unfortunately there is often ambiguity +in the use of terms throughout the audio space, so this section is intended to clarify how miniaudio +uses each term. + +3.1. Sample +----------- +A sample is a single unit of audio data. If the sample format is f32, then one sample is one 32-bit +floating point number. + +3.2. Frame / PCM Frame +---------------------- +A frame is a group of samples equal to the number of channels. For a stereo stream a frame is 2 +samples, a mono frame is 1 sample, a 5.1 surround sound frame is 6 samples, etc. The terms "frame" +and "PCM frame" are the same thing in miniaudio. Note that this is different to a compressed frame. +If ever miniaudio needs to refer to a compressed frame, such as a FLAC frame, it will always +clarify what it's referring to with something like "FLAC frame". + +3.3. Channel +------------ +A stream of monaural audio that is emitted from an individual speaker in a speaker system, or +received from an individual microphone in a microphone system. A stereo stream has two channels (a +left channel, and a right channel), a 5.1 surround sound system has 6 channels, etc. Some audio +systems refer to a channel as a complex audio stream that's mixed with other channels to produce +the final mix - this is completely different to miniaudio's use of the term "channel" and should +not be confused. + +3.4. Sample Rate +---------------- +The sample rate in miniaudio is always expressed in Hz, such as 44100, 48000, etc. It's the number +of PCM frames that are processed per second. + +3.5. Formats +------------ +Throughout miniaudio you will see references to different sample formats: + + +---------------+----------------------------------------+---------------------------+ + | Symbol | Description | Range | + +---------------+----------------------------------------+---------------------------+ + | ma_format_f32 | 32-bit floating point | [-1, 1] | + | ma_format_s16 | 16-bit signed integer | [-32768, 32767] | + | ma_format_s24 | 24-bit signed integer (tightly packed) | [-8388608, 8388607] | + | ma_format_s32 | 32-bit signed integer | [-2147483648, 2147483647] | + | ma_format_u8 | 8-bit unsigned integer | [0, 255] | + +---------------+----------------------------------------+---------------------------+ + +All formats are native-endian. + + + +4. Data Sources +=============== +The data source abstraction in miniaudio is used for retrieving audio data from some source. A few +examples include `ma_decoder`, `ma_noise` and `ma_waveform`. You will need to be familiar with data +sources in order to make sense of some of the higher level concepts in miniaudio. + +The `ma_data_source` API is a generic interface for reading from a data source. Any object that +implements the data source interface can be plugged into any `ma_data_source` function. + +To read data from a data source: + + ```c + ma_result result; + ma_uint64 framesRead; + + result = ma_data_source_read_pcm_frames(pDataSource, pFramesOut, frameCount, &framesRead); + if (result != MA_SUCCESS) { + return result; // Failed to read data from the data source. + } + ``` + +If you don't need the number of frames that were successfully read you can pass in `NULL` to the +`pFramesRead` parameter. If this returns a value less than the number of frames requested it means +the end of the file has been reached. `MA_AT_END` will be returned only when the number of frames +read is 0. + +When calling any data source function, with the exception of `ma_data_source_init()` and +`ma_data_source_uninit()`, you can pass in any object that implements a data source. For example, +you could plug in a decoder like so: + + ```c + ma_result result; + ma_uint64 framesRead; + ma_decoder decoder; // <-- This would be initialized with `ma_decoder_init_*()`. + + result = ma_data_source_read_pcm_frames(&decoder, pFramesOut, frameCount, &framesRead); + if (result != MA_SUCCESS) { + return result; // Failed to read data from the decoder. + } + ``` + +If you want to seek forward you can pass in `NULL` to the `pFramesOut` parameter. Alternatively you +can use `ma_data_source_seek_pcm_frames()`. + +To seek to a specific PCM frame: + + ```c + result = ma_data_source_seek_to_pcm_frame(pDataSource, frameIndex); + if (result != MA_SUCCESS) { + return result; // Failed to seek to PCM frame. + } + ``` + +You can retrieve the total length of a data source in PCM frames, but note that some data sources +may not have the notion of a length, such as noise and waveforms, and others may just not have a +way of determining the length such as some decoders. To retrieve the length: + + ```c + ma_uint64 length; + + result = ma_data_source_get_length_in_pcm_frames(pDataSource, &length); + if (result != MA_SUCCESS) { + return result; // Failed to retrieve the length. + } + ``` + +Care should be taken when retrieving the length of a data source where the underlying decoder is +pulling data from a data stream with an undefined length, such as internet radio or some kind of +broadcast. If you do this, `ma_data_source_get_length_in_pcm_frames()` may never return. + +The current position of the cursor in PCM frames can also be retrieved: + + ```c + ma_uint64 cursor; + + result = ma_data_source_get_cursor_in_pcm_frames(pDataSource, &cursor); + if (result != MA_SUCCESS) { + return result; // Failed to retrieve the cursor. + } + ``` + +You will often need to know the data format that will be returned after reading. This can be +retrieved like so: + + ```c + ma_format format; + ma_uint32 channels; + ma_uint32 sampleRate; + ma_channel channelMap[MA_MAX_CHANNELS]; + + result = ma_data_source_get_data_format(pDataSource, &format, &channels, &sampleRate, channelMap, MA_MAX_CHANNELS); + if (result != MA_SUCCESS) { + return result; // Failed to retrieve data format. + } + ``` + +If you do not need a specific data format property, just pass in NULL to the respective parameter. + +There may be cases where you want to implement something like a sound bank where you only want to +read data within a certain range of the underlying data. To do this you can use a range: + + ```c + result = ma_data_source_set_range_in_pcm_frames(pDataSource, rangeBegInFrames, rangeEndInFrames); + if (result != MA_SUCCESS) { + return result; // Failed to set the range. + } + ``` + +This is useful if you have a sound bank where many sounds are stored in the same file and you want +the data source to only play one of those sub-sounds. Note that once the range is set, everything +that takes a position, such as cursors and loop points, should always be relatvie to the start of +the range. When the range is set, any previously defined loop point will be reset. + +Custom loop points can also be used with data sources. By default, data sources will loop after +they reach the end of the data source, but if you need to loop at a specific location, you can do +the following: + + ```c + result = ma_data_set_loop_point_in_pcm_frames(pDataSource, loopBegInFrames, loopEndInFrames); + if (result != MA_SUCCESS) { + return result; // Failed to set the loop point. + } + ``` + +The loop point is relative to the current range. + +It's sometimes useful to chain data sources together so that a seamless transition can be achieved. +To do this, you can use chaining: + + ```c + ma_decoder decoder1; + ma_decoder decoder2; + + // ... initialize decoders with ma_decoder_init_*() ... + + result = ma_data_source_set_next(&decoder1, &decoder2); + if (result != MA_SUCCESS) { + return result; // Failed to set the next data source. + } + + result = ma_data_source_read_pcm_frames(&decoder1, pFramesOut, frameCount, pFramesRead); + if (result != MA_SUCCESS) { + return result; // Failed to read from the decoder. + } + ``` + +In the example above we're using decoders. When reading from a chain, you always want to read from +the top level data source in the chain. In the example above, `decoder1` is the top level data +source in the chain. When `decoder1` reaches the end, `decoder2` will start seamlessly without any +gaps. + +Note that when looping is enabled, only the current data source will be looped. You can loop the +entire chain by linking in a loop like so: + + ```c + ma_data_source_set_next(&decoder1, &decoder2); // decoder1 -> decoder2 + ma_data_source_set_next(&decoder2, &decoder1); // decoder2 -> decoder1 (loop back to the start). + ``` + +Note that setting up chaining is not thread safe, so care needs to be taken if you're dynamically +changing links while the audio thread is in the middle of reading. + +Do not use `ma_decoder_seek_to_pcm_frame()` as a means to reuse a data source to play multiple +instances of the same sound simultaneously. This can be extremely inefficient depending on the type +of data source and can result in glitching due to subtle changes to the state of internal filters. +Instead, initialize multiple data sources for each instance. + + +4.1. Custom Data Sources +------------------------ +You can implement a custom data source by implementing the functions in `ma_data_source_vtable`. +Your custom object must have `ma_data_source_base` as it's first member: + + ```c + struct my_data_source + { + ma_data_source_base base; + ... + }; + ``` + +In your initialization routine, you need to call `ma_data_source_init()` in order to set up the +base object (`ma_data_source_base`): + + ```c + static ma_result my_data_source_read(ma_data_source* pDataSource, void* pFramesOut, ma_uint64 frameCount, ma_uint64* pFramesRead) + { + // Read data here. Output in the same format returned by my_data_source_get_data_format(). + } + + static ma_result my_data_source_seek(ma_data_source* pDataSource, ma_uint64 frameIndex) + { + // Seek to a specific PCM frame here. Return MA_NOT_IMPLEMENTED if seeking is not supported. + } + + static ma_result my_data_source_get_data_format(ma_data_source* pDataSource, ma_format* pFormat, ma_uint32* pChannels, ma_uint32* pSampleRate, ma_channel* pChannelMap, size_t channelMapCap) + { + // Return the format of the data here. + } + + static ma_result my_data_source_get_cursor(ma_data_source* pDataSource, ma_uint64* pCursor) + { + // Retrieve the current position of the cursor here. Return MA_NOT_IMPLEMENTED and set *pCursor to 0 if there is no notion of a cursor. + } + + static ma_result my_data_source_get_length(ma_data_source* pDataSource, ma_uint64* pLength) + { + // Retrieve the length in PCM frames here. Return MA_NOT_IMPLEMENTED and set *pLength to 0 if there is no notion of a length or if the length is unknown. + } + + static ma_data_source_vtable g_my_data_source_vtable = + { + my_data_source_read, + my_data_source_seek, + my_data_source_get_data_format, + my_data_source_get_cursor, + my_data_source_get_length + }; + + ma_result my_data_source_init(my_data_source* pMyDataSource) + { + ma_result result; + ma_data_source_config baseConfig; + + baseConfig = ma_data_source_config_init(); + baseConfig.vtable = &g_my_data_source_vtable; + + result = ma_data_source_init(&baseConfig, &pMyDataSource->base); + if (result != MA_SUCCESS) { + return result; + } + + // ... do the initialization of your custom data source here ... + + return MA_SUCCESS; + } + + void my_data_source_uninit(my_data_source* pMyDataSource) + { + // ... do the uninitialization of your custom data source here ... + + // You must uninitialize the base data source. + ma_data_source_uninit(&pMyDataSource->base); + } + ``` + +Note that `ma_data_source_init()` and `ma_data_source_uninit()` are never called directly outside +of the custom data source. It's up to the custom data source itself to call these within their own +init/uninit functions. + + + +5. Engine +========= +The `ma_engine` API is a high level API for managing and mixing sounds and effect processing. The +`ma_engine` object encapsulates a resource manager and a node graph, both of which will be +explained in more detail later. + +Sounds are called `ma_sound` and are created from an engine. Sounds can be associated with a mixing +group called `ma_sound_group` which are also created from the engine. Both `ma_sound` and +`ma_sound_group` objects are nodes within the engine's node graph. + +When the engine is initialized, it will normally create a device internally. If you would rather +manage the device yourself, you can do so and just pass a pointer to it via the engine config when +you initialize the engine. You can also just use the engine without a device, which again can be +configured via the engine config. + +The most basic way to initialize the engine is with a default config, like so: + + ```c + ma_result result; + ma_engine engine; + + result = ma_engine_init(NULL, &engine); + if (result != MA_SUCCESS) { + return result; // Failed to initialize the engine. + } + ``` + +This will result in the engine initializing a playback device using the operating system's default +device. This will be sufficient for many use cases, but if you need more flexibility you'll want to +configure the engine with an engine config: + + ```c + ma_result result; + ma_engine engine; + ma_engine_config engineConfig; + + engineConfig = ma_engine_config_init(); + engineConfig.pDevice = &myDevice; + + result = ma_engine_init(&engineConfig, &engine); + if (result != MA_SUCCESS) { + return result; // Failed to initialize the engine. + } + ``` + +In the example above we're passing in a pre-initialized device. Since the caller is the one in +control of the device's data callback, it's their responsibility to manually call +`ma_engine_read_pcm_frames()` from inside their data callback: + + ```c + void playback_data_callback(ma_device* pDevice, void* pOutput, const void* pInput, ma_uint32 frameCount) + { + ma_engine_read_pcm_frames(&g_Engine, pOutput, frameCount, NULL); + } + ``` + +You can also use the engine independent of a device entirely: + + ```c + ma_result result; + ma_engine engine; + ma_engine_config engineConfig; + + engineConfig = ma_engine_config_init(); + engineConfig.noDevice = MA_TRUE; + engineConfig.channels = 2; // Must be set when not using a device. + engineConfig.sampleRate = 48000; // Must be set when not using a device. + + result = ma_engine_init(&engineConfig, &engine); + if (result != MA_SUCCESS) { + return result; // Failed to initialize the engine. + } + ``` + +Note that when you're not using a device, you must set the channel count and sample rate in the +config or else miniaudio won't know what to use (miniaudio will use the device to determine this +normally). When not using a device, you need to use `ma_engine_read_pcm_frames()` to process audio +data from the engine. This kind of setup is useful if you want to do something like offline +processing or want to use a different audio system for playback such as SDL. + +When a sound is loaded it goes through a resource manager. By default the engine will initialize a +resource manager internally, but you can also specify a pre-initialized resource manager: + + ```c + ma_result result; + ma_engine engine1; + ma_engine engine2; + ma_engine_config engineConfig; + + engineConfig = ma_engine_config_init(); + engineConfig.pResourceManager = &myResourceManager; + + ma_engine_init(&engineConfig, &engine1); + ma_engine_init(&engineConfig, &engine2); + ``` + +In this example we are initializing two engines, both of which are sharing the same resource +manager. This is especially useful for saving memory when loading the same file across multiple +engines. If you were not to use a shared resource manager, each engine instance would use their own +which would result in any sounds that are used between both engine's being loaded twice. By using +a shared resource manager, it would only be loaded once. Using multiple engine's is useful when you +need to output to multiple playback devices, such as in a local multiplayer game where each player +is using their own set of headphones. + +By default an engine will be in a started state. To make it so the engine is not automatically +started you can configure it as such: + + ```c + engineConfig.noAutoStart = MA_TRUE; + + // The engine will need to be started manually. + ma_engine_start(&engine); + + // Later on the engine can be stopped with ma_engine_stop(). + ma_engine_stop(&engine); + ``` + +The concept of starting or stopping an engine is only relevant when using the engine with a +device. Attempting to start or stop an engine that is not associated with a device will result in +`MA_INVALID_OPERATION`. + +The master volume of the engine can be controlled with `ma_engine_set_volume()` which takes a +linear scale, with 0 resulting in silence and anything above 1 resulting in amplification. If you +prefer decibel based volume control, use `ma_volume_db_to_linear()` to convert from dB to linear. + +When a sound is spatialized, it is done so relative to a listener. An engine can be configured to +have multiple listeners which can be configured via the config: + + ```c + engineConfig.listenerCount = 2; + ``` + +The maximum number of listeners is restricted to `MA_ENGINE_MAX_LISTENERS`. By default, when a +sound is spatialized, it will be done so relative to the closest listener. You can also pin a sound +to a specific listener which will be explained later. Listener's have a position, direction, cone, +and velocity (for doppler effect). A listener is referenced by an index, the meaning of which is up +to the caller (the index is 0 based and cannot go beyond the listener count, minus 1). The +position, direction and velocity are all specified in absolute terms: + + ```c + ma_engine_listener_set_position(&engine, listenerIndex, worldPosX, worldPosY, worldPosZ); + ``` + +The direction of the listener represents it's forward vector. The listener's up vector can also be +specified and defaults to +1 on the Y axis. + + ```c + ma_engine_listener_set_direction(&engine, listenerIndex, forwardX, forwardY, forwardZ); + ma_engine_listener_set_world_up(&engine, listenerIndex, 0, 1, 0); + ``` + +The engine supports directional attenuation. The listener can have a cone the controls how sound is +attenuated based on the listener's direction. When a sound is between the inner and outer cones, it +will be attenuated between 1 and the cone's outer gain: + + ```c + ma_engine_listener_set_cone(&engine, listenerIndex, innerAngleInRadians, outerAngleInRadians, outerGain); + ``` + +When a sound is inside the inner code, no directional attenuation is applied. When the sound is +outside of the outer cone, the attenuation will be set to `outerGain` in the example above. When +the sound is in between the inner and outer cones, the attenuation will be interpolated between 1 +and the outer gain. + +The engine's coordinate system follows the OpenGL coordinate system where positive X points right, +positive Y points up and negative Z points forward. + +The simplest and least flexible way to play a sound is like so: + + ```c + ma_engine_play_sound(&engine, "my_sound.wav", pGroup); + ``` + +This is a "fire and forget" style of function. The engine will manage the `ma_sound` object +internally. When the sound finishes playing, it'll be put up for recycling. For more flexibility +you'll want to initialize a sound object: + + ```c + ma_sound sound; + + result = ma_sound_init_from_file(&engine, "my_sound.wav", flags, pGroup, NULL, &sound); + if (result != MA_SUCCESS) { + return result; // Failed to load sound. + } + ``` + +Sounds need to be uninitialized with `ma_sound_uninit()`. + +The example above loads a sound from a file. If the resource manager has been disabled you will not +be able to use this function and instead you'll need to initialize a sound directly from a data +source: + + ```c + ma_sound sound; + + result = ma_sound_init_from_data_source(&engine, &dataSource, flags, pGroup, &sound); + if (result != MA_SUCCESS) { + return result; + } + ``` + +Each `ma_sound` object represents a single instance of the sound. If you want to play the same +sound multiple times at the same time, you need to initialize a separate `ma_sound` object. + +For the most flexibility when initializing sounds, use `ma_sound_init_ex()`. This uses miniaudio's +standard config/init pattern: + + ```c + ma_sound sound; + ma_sound_config soundConfig; + + soundConfig = ma_sound_config_init(); + soundConfig.pFilePath = NULL; // Set this to load from a file path. + soundConfig.pDataSource = NULL; // Set this to initialize from an existing data source. + soundConfig.pInitialAttachment = &someNodeInTheNodeGraph; + soundConfig.initialAttachmentInputBusIndex = 0; + soundConfig.channelsIn = 1; + soundConfig.channelsOut = 0; // Set to 0 to use the engine's native channel count. + + result = ma_sound_init_ex(&soundConfig, &sound); + if (result != MA_SUCCESS) { + return result; + } + ``` + +In the example above, the sound is being initialized without a file nor a data source. This is +valid, in which case the sound acts as a node in the middle of the node graph. This means you can +connect other sounds to this sound and allow it to act like a sound group. Indeed, this is exactly +what a `ma_sound_group` is. + +When loading a sound, you specify a set of flags that control how the sound is loaded and what +features are enabled for that sound. When no flags are set, the sound will be fully loaded into +memory in exactly the same format as how it's stored on the file system. The resource manager will +allocate a block of memory and then load the file directly into it. When reading audio data, it +will be decoded dynamically on the fly. In order to save processing time on the audio thread, it +might be beneficial to pre-decode the sound. You can do this with the `MA_SOUND_FLAG_DECODE` flag: + + ```c + ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_DECODE, pGroup, NULL, &sound); + ``` + +By default, sounds will be loaded synchronously, meaning `ma_sound_init_*()` will not return until +the sound has been fully loaded. If this is prohibitive you can instead load sounds asynchronously +by specifying the `MA_SOUND_FLAG_ASYNC` flag: + + ```c + ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_DECODE | MA_SOUND_FLAG_ASYNC, pGroup, NULL, &sound); + ``` + +This will result in `ma_sound_init_*()` returning quickly, but the sound won't yet have been fully +loaded. When you start the sound, it won't output anything until some sound is available. The sound +will start outputting audio before the sound has been fully decoded when the `MA_SOUND_FLAG_DECODE` +is specified. + +If you need to wait for an asynchronously loaded sound to be fully loaded, you can use a fence. A +fence in miniaudio is a simple synchronization mechanism which simply blocks until it's internal +counter hit's zero. You can specify a fence like so: + + ```c + ma_result result; + ma_fence fence; + ma_sound sounds[4]; + + result = ma_fence_init(&fence); + if (result != MA_SUCCESS) { + return result; + } + + // Load some sounds asynchronously. + for (int iSound = 0; iSound < 4; iSound += 1) { + ma_sound_init_from_file(&engine, mySoundFilesPaths[iSound], MA_SOUND_FLAG_DECODE | MA_SOUND_FLAG_ASYNC, pGroup, &fence, &sounds[iSound]); + } + + // ... do some other stuff here in the mean time ... + + // Wait for all sounds to finish loading. + ma_fence_wait(&fence); + ``` + +If loading the entire sound into memory is prohibitive, you can also configure the engine to stream +the audio data: + + ```c + ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_STREAM, pGroup, NULL, &sound); + ``` + +When streaming sounds, 2 seconds worth of audio data is stored in memory. Although it should work +fine, it's inefficient to use streaming for short sounds. Streaming is useful for things like music +tracks in games. + +When loading a sound from a file path, the engine will reference count the file to prevent it from +being loaded if it's already in memory. When you uninitialize a sound, the reference count will be +decremented, and if it hits zero, the sound will be unloaded from memory. This reference counting +system is not used for streams. The engine will use a 64-bit hash of the file name when comparing +file paths which means there's a small chance you might encounter a name collision. If this is an +issue, you'll need to use a different name for one of the colliding file paths, or just not load +from files and instead load from a data source. + +You can use `ma_sound_init_copy()` to initialize a copy of another sound. Note, however, that this +only works for sounds that were initialized with `ma_sound_init_from_file()` and without the +`MA_SOUND_FLAG_STREAM` flag. + +When you initialize a sound, if you specify a sound group the sound will be attached to that group +automatically. If you set it to NULL, it will be automatically attached to the engine's endpoint. +If you would instead rather leave the sound unattached by default, you can can specify the +`MA_SOUND_FLAG_NO_DEFAULT_ATTACHMENT` flag. This is useful if you want to set up a complex node +graph. + +Sounds are not started by default. To start a sound, use `ma_sound_start()`. Stop a sound with +`ma_sound_stop()`. + +Sounds can have their volume controlled with `ma_sound_set_volume()` in the same way as the +engine's master volume. + +Sounds support stereo panning and pitching. Set the pan with `ma_sound_set_pan()`. Setting the pan +to 0 will result in an unpanned sound. Setting it to -1 will shift everything to the left, whereas ++1 will shift it to the right. The pitch can be controlled with `ma_sound_set_pitch()`. A larger +value will result in a higher pitch. The pitch must be greater than 0. + +The engine supports 3D spatialization of sounds. By default sounds will have spatialization +enabled, but if a sound does not need to be spatialized it's best to disable it. There are two ways +to disable spatialization of a sound: + + ```c + // Disable spatialization at initialization time via a flag: + ma_sound_init_from_file(&engine, "my_sound.wav", MA_SOUND_FLAG_NO_SPATIALIZATION, NULL, NULL, &sound); + + // Dynamically disable or enable spatialization post-initialization: + ma_sound_set_spatialization_enabled(&sound, isSpatializationEnabled); + ``` + +By default sounds will be spatialized based on the closest listener. If a sound should always be +spatialized relative to a specific listener it can be pinned to one: + + ```c + ma_sound_set_pinned_listener_index(&sound, listenerIndex); + ``` + +Like listeners, sounds have a position. By default, the position of a sound is in absolute space, +but it can be changed to be relative to a listener: + + ```c + ma_sound_set_positioning(&sound, ma_positioning_relative); + ``` + +Note that relative positioning of a sound only makes sense if there is either only one listener, or +the sound is pinned to a specific listener. To set the position of a sound: + + ```c + ma_sound_set_position(&sound, posX, posY, posZ); + ``` + +The direction works the same way as a listener and represents the sound's forward direction: + + ```c + ma_sound_set_direction(&sound, forwardX, forwardY, forwardZ); + ``` + +Sound's also have a cone for controlling directional attenuation. This works exactly the same as +listeners: + + ```c + ma_sound_set_cone(&sound, innerAngleInRadians, outerAngleInRadians, outerGain); + ``` + +The velocity of a sound is used for doppler effect and can be set as such: + + ```c + ma_sound_set_velocity(&sound, velocityX, velocityY, velocityZ); + ``` + +The engine supports different attenuation models which can be configured on a per-sound basis. By +default the attenuation model is set to `ma_attenuation_model_inverse` which is the equivalent to +OpenAL's `AL_INVERSE_DISTANCE_CLAMPED`. Configure the attenuation model like so: + + ```c + ma_sound_set_attenuation_model(&sound, ma_attenuation_model_inverse); + ``` + +The supported attenuation models include the following: + + +----------------------------------+----------------------------------------------+ + | ma_attenuation_model_none | No distance attenuation. | + +----------------------------------+----------------------------------------------+ + | ma_attenuation_model_inverse | Equivalent to `AL_INVERSE_DISTANCE_CLAMPED`. | + +----------------------------------+----------------------------------------------+ + | ma_attenuation_model_linear | Linear attenuation. | + +----------------------------------+----------------------------------------------+ + | ma_attenuation_model_exponential | Exponential attenuation. | + +----------------------------------+----------------------------------------------+ + +To control how quickly a sound rolls off as it moves away from the listener, you need to configure +the rolloff: + + ```c + ma_sound_set_rolloff(&sound, rolloff); + ``` + +You can control the minimum and maximum gain to apply from spatialization: + + ```c + ma_sound_set_min_gain(&sound, minGain); + ma_sound_set_max_gain(&sound, maxGain); + ``` + +Likewise, in the calculation of attenuation, you can control the minimum and maximum distances for +the attenuation calculation. This is useful if you want to ensure sounds don't drop below a certain +volume after the listener moves further away and to have sounds play a maximum volume when the +listener is within a certain distance: + + ```c + ma_sound_set_min_distance(&sound, minDistance); + ma_sound_set_max_distance(&sound, maxDistance); + ``` + +The engine's spatialization system supports doppler effect. The doppler factor can be configure on +a per-sound basis like so: + + ```c + ma_sound_set_doppler_factor(&sound, dopplerFactor); + ``` + +You can fade sounds in and out with `ma_sound_set_fade_in_pcm_frames()` and +`ma_sound_set_fade_in_milliseconds()`. Set the volume to -1 to use the current volume as the +starting volume: + + ```c + // Fade in over 1 second. + ma_sound_set_fade_in_milliseconds(&sound, 0, 1, 1000); + + // ... sometime later ... + + // Fade out over 1 second, starting from the current volume. + ma_sound_set_fade_in_milliseconds(&sound, -1, 0, 1000); + ``` + +By default sounds will start immediately, but sometimes for timing and synchronization purposes it +can be useful to schedule a sound to start or stop: + + ```c + // Start the sound in 1 second from now. + ma_sound_set_start_time_in_pcm_frames(&sound, ma_engine_get_time_in_pcm_frames(&engine) + (ma_engine_get_sample_rate(&engine) * 1)); + + // Stop the sound in 2 seconds from now. + ma_sound_set_stop_time_in_pcm_frames(&sound, ma_engine_get_time_in_pcm_frames(&engine) + (ma_engine_get_sample_rate(&engine) * 2)); + ``` + +Note that scheduling a start time still requires an explicit call to `ma_sound_start()` before +anything will play. + +The time is specified in global time which is controlled by the engine. You can get the engine's +current time with `ma_engine_get_time_in_pcm_frames()`. The engine's global time is incremented +automatically as audio data is read, but it can be reset with `ma_engine_set_time_in_pcm_frames()` +in case it needs to be resynchronized for some reason. + +To determine whether or not a sound is currently playing, use `ma_sound_is_playing()`. This will +take the scheduled start and stop times into account. + +Whether or not a sound should loop can be controlled with `ma_sound_set_looping()`. Sounds will not +be looping by default. Use `ma_sound_is_looping()` to determine whether or not a sound is looping. + +Use `ma_sound_at_end()` to determine whether or not a sound is currently at the end. For a looping +sound this should never return true. Alternatively, you can configure a callback that will be fired +when the sound reaches the end. Note that the callback is fired from the audio thread which means +you cannot be uninitializing sound from the callback. To set the callback you can use +`ma_sound_set_end_callback()`. Alternatively, if you're using `ma_sound_init_ex()`, you can pass it +into the config like so: + + ```c + soundConfig.endCallback = my_end_callback; + soundConfig.pEndCallbackUserData = pMyEndCallbackUserData; + ``` + +The end callback is declared like so: + + ```c + void my_end_callback(void* pUserData, ma_sound* pSound) + { + ... + } + ``` + +Internally a sound wraps around a data source. Some APIs exist to control the underlying data +source, mainly for convenience: + + ```c + ma_sound_seek_to_pcm_frame(&sound, frameIndex); + ma_sound_get_data_format(&sound, &format, &channels, &sampleRate, pChannelMap, channelMapCapacity); + ma_sound_get_cursor_in_pcm_frames(&sound, &cursor); + ma_sound_get_length_in_pcm_frames(&sound, &length); + ``` + +Sound groups have the same API as sounds, only they are called `ma_sound_group`, and since they do +not have any notion of a data source, anything relating to a data source is unavailable. + +Internally, sound data is loaded via the `ma_decoder` API which means by default it only supports +file formats that have built-in support in miniaudio. You can extend this to support any kind of +file format through the use of custom decoders. To do this you'll need to use a self-managed +resource manager and configure it appropriately. See the "Resource Management" section below for +details on how to set this up. + + +6. Resource Management +====================== +Many programs will want to manage sound resources for things such as reference counting and +streaming. This is supported by miniaudio via the `ma_resource_manager` API. + +The resource manager is mainly responsible for the following: + + * Loading of sound files into memory with reference counting. + * Streaming of sound data. + +When loading a sound file, the resource manager will give you back a `ma_data_source` compatible +object called `ma_resource_manager_data_source`. This object can be passed into any +`ma_data_source` API which is how you can read and seek audio data. When loading a sound file, you +specify whether or not you want the sound to be fully loaded into memory (and optionally +pre-decoded) or streamed. When loading into memory, you can also specify whether or not you want +the data to be loaded asynchronously. + +The example below is how you can initialize a resource manager using it's default configuration: + + ```c + ma_resource_manager_config config; + ma_resource_manager resourceManager; + + config = ma_resource_manager_config_init(); + result = ma_resource_manager_init(&config, &resourceManager); + if (result != MA_SUCCESS) { + ma_device_uninit(&device); + printf("Failed to initialize the resource manager."); + return -1; + } + ``` + +You can configure the format, channels and sample rate of the decoded audio data. By default it +will use the file's native data format, but you can configure it to use a consistent format. This +is useful for offloading the cost of data conversion to load time rather than dynamically +converting at mixing time. To do this, you configure the decoded format, channels and sample rate +like the code below: + + ```c + config = ma_resource_manager_config_init(); + config.decodedFormat = device.playback.format; + config.decodedChannels = device.playback.channels; + config.decodedSampleRate = device.sampleRate; + ``` + +In the code above, the resource manager will be configured so that any decoded audio data will be +pre-converted at load time to the device's native data format. If instead you used defaults and +the data format of the file did not match the device's data format, you would need to convert the +data at mixing time which may be prohibitive in high-performance and large scale scenarios like +games. + +Internally the resource manager uses the `ma_decoder` API to load sounds. This means by default it +only supports decoders that are built into miniaudio. It's possible to support additional encoding +formats through the use of custom decoders. To do so, pass in your `ma_decoding_backend_vtable` +vtables into the resource manager config: + + ```c + ma_decoding_backend_vtable* pCustomBackendVTables[] = + { + &g_ma_decoding_backend_vtable_libvorbis, + &g_ma_decoding_backend_vtable_libopus + }; + + ... + + resourceManagerConfig.ppCustomDecodingBackendVTables = pCustomBackendVTables; + resourceManagerConfig.customDecodingBackendCount = sizeof(pCustomBackendVTables) / sizeof(pCustomBackendVTables[0]); + resourceManagerConfig.pCustomDecodingBackendUserData = NULL; + ``` + +This system can allow you to support any kind of file format. See the "Decoding" section for +details on how to implement custom decoders. The miniaudio repository includes examples for Opus +via libopus and libopusfile and Vorbis via libvorbis and libvorbisfile. + +Asynchronicity is achieved via a job system. When an operation needs to be performed, such as the +decoding of a page, a job will be posted to a queue which will then be processed by a job thread. +By default there will be only one job thread running, but this can be configured, like so: + + ```c + config = ma_resource_manager_config_init(); + config.jobThreadCount = MY_JOB_THREAD_COUNT; + ``` + +By default job threads are managed internally by the resource manager, however you can also self +manage your job threads if, for example, you want to integrate the job processing into your +existing job infrastructure, or if you simply don't like the way the resource manager does it. To +do this, just set the job thread count to 0 and process jobs manually. To process jobs, you first +need to retrieve a job using `ma_resource_manager_next_job()` and then process it using +`ma_job_process()`: + + ```c + config = ma_resource_manager_config_init(); + config.jobThreadCount = 0; // Don't manage any job threads internally. + config.flags = MA_RESOURCE_MANAGER_FLAG_NON_BLOCKING; // Optional. Makes `ma_resource_manager_next_job()` non-blocking. + + // ... Initialize your custom job threads ... + + void my_custom_job_thread(...) + { + for (;;) { + ma_job job; + ma_result result = ma_resource_manager_next_job(pMyResourceManager, &job); + if (result != MA_SUCCESS) { + if (result == MA_NO_DATA_AVAILABLE) { + // No jobs are available. Keep going. Will only get this if the resource manager was initialized + // with MA_RESOURCE_MANAGER_FLAG_NON_BLOCKING. + continue; + } else if (result == MA_CANCELLED) { + // MA_JOB_TYPE_QUIT was posted. Exit. + break; + } else { + // Some other error occurred. + break; + } + } + + ma_job_process(&job); + } + } + ``` + +In the example above, the `MA_JOB_TYPE_QUIT` event is the used as the termination +indicator, but you can use whatever you would like to terminate the thread. The call to +`ma_resource_manager_next_job()` is blocking by default, but can be configured to be non-blocking +by initializing the resource manager with the `MA_RESOURCE_MANAGER_FLAG_NON_BLOCKING` configuration +flag. Note that the `MA_JOB_TYPE_QUIT` will never be removed from the job queue. This +is to give every thread the opportunity to catch the event and terminate naturally. + +When loading a file, it's sometimes convenient to be able to customize how files are opened and +read instead of using standard `fopen()`, `fclose()`, etc. which is what miniaudio will use by +default. This can be done by setting `pVFS` member of the resource manager's config: + + ```c + // Initialize your custom VFS object. See documentation for VFS for information on how to do this. + my_custom_vfs vfs = my_custom_vfs_init(); + + config = ma_resource_manager_config_init(); + config.pVFS = &vfs; + ``` + +This is particularly useful in programs like games where you want to read straight from an archive +rather than the normal file system. If you do not specify a custom VFS, the resource manager will +use the operating system's normal file operations. + +To load a sound file and create a data source, call `ma_resource_manager_data_source_init()`. When +loading a sound you need to specify the file path and options for how the sounds should be loaded. +By default a sound will be loaded synchronously. The returned data source is owned by the caller +which means the caller is responsible for the allocation and freeing of the data source. Below is +an example for initializing a data source: + + ```c + ma_resource_manager_data_source dataSource; + ma_result result = ma_resource_manager_data_source_init(pResourceManager, pFilePath, flags, &dataSource); + if (result != MA_SUCCESS) { + // Error. + } + + // ... + + // A ma_resource_manager_data_source object is compatible with the `ma_data_source` API. To read data, just call + // the `ma_data_source_read_pcm_frames()` like you would with any normal data source. + result = ma_data_source_read_pcm_frames(&dataSource, pDecodedData, frameCount, &framesRead); + if (result != MA_SUCCESS) { + // Failed to read PCM frames. + } + + // ... + + ma_resource_manager_data_source_uninit(&dataSource); + ``` + +The `flags` parameter specifies how you want to perform loading of the sound file. It can be a +combination of the following flags: + + ``` + MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM + MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_DECODE + MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_ASYNC + MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_WAIT_INIT + ``` + +When no flags are specified (set to 0), the sound will be fully loaded into memory, but not +decoded, meaning the raw file data will be stored in memory, and then dynamically decoded when +`ma_data_source_read_pcm_frames()` is called. To instead decode the audio data before storing it in +memory, use the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_DECODE` flag. By default, the sound file will +be loaded synchronously, meaning `ma_resource_manager_data_source_init()` will only return after +the entire file has been loaded. This is good for simplicity, but can be prohibitively slow. You +can instead load the sound asynchronously using the `MA_RESOURCE_MANAGER_DATA_SOURCE_ASYNC` flag. +This will result in `ma_resource_manager_data_source_init()` returning quickly, but no data will be +returned by `ma_data_source_read_pcm_frames()` until some data is available. When no data is +available because the asynchronous decoding hasn't caught up, `MA_BUSY` will be returned by +`ma_data_source_read_pcm_frames()`. + +For large sounds, it's often prohibitive to store the entire file in memory. To mitigate this, you +can instead stream audio data which you can do by specifying the +`MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag. When streaming, data will be decoded in 1 +second pages. When a new page needs to be decoded, a job will be posted to the job queue and then +subsequently processed in a job thread. + +For in-memory sounds, reference counting is used to ensure the data is loaded only once. This means +multiple calls to `ma_resource_manager_data_source_init()` with the same file path will result in +the file data only being loaded once. Each call to `ma_resource_manager_data_source_init()` must be +matched up with a call to `ma_resource_manager_data_source_uninit()`. Sometimes it can be useful +for a program to register self-managed raw audio data and associate it with a file path. Use the +`ma_resource_manager_register_*()` and `ma_resource_manager_unregister_*()` APIs to do this. +`ma_resource_manager_register_decoded_data()` is used to associate a pointer to raw, self-managed +decoded audio data in the specified data format with the specified name. Likewise, +`ma_resource_manager_register_encoded_data()` is used to associate a pointer to raw self-managed +encoded audio data (the raw file data) with the specified name. Note that these names need not be +actual file paths. When `ma_resource_manager_data_source_init()` is called (without the +`MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag), the resource manager will look for these +explicitly registered data buffers and, if found, will use it as the backing data for the data +source. Note that the resource manager does *not* make a copy of this data so it is up to the +caller to ensure the pointer stays valid for it's lifetime. Use +`ma_resource_manager_unregister_data()` to unregister the self-managed data. You can also use +`ma_resource_manager_register_file()` and `ma_resource_manager_unregister_file()` to register and +unregister a file. It does not make sense to use the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` +flag with a self-managed data pointer. + + +6.1. Asynchronous Loading and Synchronization +--------------------------------------------- +When loading asynchronously, it can be useful to poll whether or not loading has finished. Use +`ma_resource_manager_data_source_result()` to determine this. For in-memory sounds, this will +return `MA_SUCCESS` when the file has been *entirely* decoded. If the sound is still being decoded, +`MA_BUSY` will be returned. Otherwise, some other error code will be returned if the sound failed +to load. For streaming data sources, `MA_SUCCESS` will be returned when the first page has been +decoded and the sound is ready to be played. If the first page is still being decoded, `MA_BUSY` +will be returned. Otherwise, some other error code will be returned if the sound failed to load. + +In addition to polling, you can also use a simple synchronization object called a "fence" to wait +for asynchronously loaded sounds to finish. This is called `ma_fence`. The advantage to using a +fence is that it can be used to wait for a group of sounds to finish loading rather than waiting +for sounds on an individual basis. There are two stages to loading a sound: + + * Initialization of the internal decoder; and + * Completion of decoding of the file (the file is fully decoded) + +You can specify separate fences for each of the different stages. Waiting for the initialization +of the internal decoder is important for when you need to know the sample format, channels and +sample rate of the file. + +The example below shows how you could use a fence when loading a number of sounds: + + ```c + // This fence will be released when all sounds are finished loading entirely. + ma_fence fence; + ma_fence_init(&fence); + + // This will be passed into the initialization routine for each sound. + ma_resource_manager_pipeline_notifications notifications = ma_resource_manager_pipeline_notifications_init(); + notifications.done.pFence = &fence; + + // Now load a bunch of sounds: + for (iSound = 0; iSound < soundCount; iSound += 1) { + ma_resource_manager_data_source_init(pResourceManager, pSoundFilePaths[iSound], flags, ¬ifications, &pSoundSources[iSound]); + } + + // ... DO SOMETHING ELSE WHILE SOUNDS ARE LOADING ... + + // Wait for loading of sounds to finish. + ma_fence_wait(&fence); + ``` + +In the example above we used a fence for waiting until the entire file has been fully decoded. If +you only need to wait for the initialization of the internal decoder to complete, you can use the +`init` member of the `ma_resource_manager_pipeline_notifications` object: + + ```c + notifications.init.pFence = &fence; + ``` + +If a fence is not appropriate for your situation, you can instead use a callback that is fired on +an individual sound basis. This is done in a very similar way to fences: + + ```c + typedef struct + { + ma_async_notification_callbacks cb; + void* pMyData; + } my_notification; + + void my_notification_callback(ma_async_notification* pNotification) + { + my_notification* pMyNotification = (my_notification*)pNotification; + + // Do something in response to the sound finishing loading. + } + + ... + + my_notification myCallback; + myCallback.cb.onSignal = my_notification_callback; + myCallback.pMyData = pMyData; + + ma_resource_manager_pipeline_notifications notifications = ma_resource_manager_pipeline_notifications_init(); + notifications.done.pNotification = &myCallback; + + ma_resource_manager_data_source_init(pResourceManager, "my_sound.wav", flags, ¬ifications, &mySound); + ``` + +In the example above we just extend the `ma_async_notification_callbacks` object and pass an +instantiation into the `ma_resource_manager_pipeline_notifications` in the same way as we did with +the fence, only we set `pNotification` instead of `pFence`. You can set both of these at the same +time and they should both work as expected. If using the `pNotification` system, you need to ensure +your `ma_async_notification_callbacks` object stays valid. + + + +6.2. Resource Manager Implementation Details +-------------------------------------------- +Resources are managed in two main ways: + + * By storing the entire sound inside an in-memory buffer (referred to as a data buffer) + * By streaming audio data on the fly (referred to as a data stream) + +A resource managed data source (`ma_resource_manager_data_source`) encapsulates a data buffer or +data stream, depending on whether or not the data source was initialized with the +`MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag. If so, it will make use of a +`ma_resource_manager_data_stream` object. Otherwise it will use a `ma_resource_manager_data_buffer` +object. Both of these objects are data sources which means they can be used with any +`ma_data_source_*()` API. + +Another major feature of the resource manager is the ability to asynchronously decode audio files. +This relieves the audio thread of time-consuming decoding which can negatively affect scalability +due to the audio thread needing to complete it's work extremely quickly to avoid glitching. +Asynchronous decoding is achieved through a job system. There is a central multi-producer, +multi-consumer, fixed-capacity job queue. When some asynchronous work needs to be done, a job is +posted to the queue which is then read by a job thread. The number of job threads can be +configured for improved scalability, and job threads can all run in parallel without needing to +worry about the order of execution (how this is achieved is explained below). + +When a sound is being loaded asynchronously, playback can begin before the sound has been fully +decoded. This enables the application to start playback of the sound quickly, while at the same +time allowing to resource manager to keep loading in the background. Since there may be less +threads than the number of sounds being loaded at a given time, a simple scheduling system is used +to keep decoding time balanced and fair. The resource manager solves this by splitting decoding +into chunks called pages. By default, each page is 1 second long. When a page has been decoded, a +new job will be posted to start decoding the next page. By dividing up decoding into pages, an +individual sound shouldn't ever delay every other sound from having their first page decoded. Of +course, when loading many sounds at the same time, there will always be an amount of time required +to process jobs in the queue so in heavy load situations there will still be some delay. To +determine if a data source is ready to have some frames read, use +`ma_resource_manager_data_source_get_available_frames()`. This will return the number of frames +available starting from the current position. + + +6.2.1. Job Queue +---------------- +The resource manager uses a job queue which is multi-producer, multi-consumer, and fixed-capacity. +This job queue is not currently lock-free, and instead uses a spinlock to achieve thread-safety. +Only a fixed number of jobs can be allocated and inserted into the queue which is done through a +lock-free data structure for allocating an index into a fixed sized array, with reference counting +for mitigation of the ABA problem. The reference count is 32-bit. + +For many types of jobs it's important that they execute in a specific order. In these cases, jobs +are executed serially. For the resource manager, serial execution of jobs is only required on a +per-object basis (per data buffer or per data stream). Each of these objects stores an execution +counter. When a job is posted it is associated with an execution counter. When the job is +processed, it checks if the execution counter of the job equals the execution counter of the +owning object and if so, processes the job. If the counters are not equal, the job will be posted +back onto the job queue for later processing. When the job finishes processing the execution order +of the main object is incremented. This system means the no matter how many job threads are +executing, decoding of an individual sound will always get processed serially. The advantage to +having multiple threads comes into play when loading multiple sounds at the same time. + +The resource manager's job queue is not 100% lock-free and will use a spinlock to achieve +thread-safety for a very small section of code. This is only relevant when the resource manager +uses more than one job thread. If only using a single job thread, which is the default, the +lock should never actually wait in practice. The amount of time spent locking should be quite +short, but it's something to be aware of for those who have pedantic lock-free requirements and +need to use more than one job thread. There are plans to remove this lock in a future version. + +In addition, posting a job will release a semaphore, which on Win32 is implemented with +`ReleaseSemaphore` and on POSIX platforms via a condition variable: + + ```c + pthread_mutex_lock(&pSemaphore->lock); + { + pSemaphore->value += 1; + pthread_cond_signal(&pSemaphore->cond); + } + pthread_mutex_unlock(&pSemaphore->lock); + ``` + +Again, this is relevant for those with strict lock-free requirements in the audio thread. To avoid +this, you can use non-blocking mode (via the `MA_JOB_QUEUE_FLAG_NON_BLOCKING` +flag) and implement your own job processing routine (see the "Resource Manager" section above for +details on how to do this). + + + +6.2.2. Data Buffers +------------------- +When the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_STREAM` flag is excluded at initialization time, the +resource manager will try to load the data into an in-memory data buffer. Before doing so, however, +it will first check if the specified file is already loaded. If so, it will increment a reference +counter and just use the already loaded data. This saves both time and memory. When the data buffer +is uninitialized, the reference counter will be decremented. If the counter hits zero, the file +will be unloaded. This is a detail to keep in mind because it could result in excessive loading and +unloading of a sound. For example, the following sequence will result in a file be loaded twice, +once after the other: + + ```c + ma_resource_manager_data_source_init(pResourceManager, "my_file", ..., &myDataBuffer0); // Refcount = 1. Initial load. + ma_resource_manager_data_source_uninit(&myDataBuffer0); // Refcount = 0. Unloaded. + + ma_resource_manager_data_source_init(pResourceManager, "my_file", ..., &myDataBuffer1); // Refcount = 1. Reloaded because previous uninit() unloaded it. + ma_resource_manager_data_source_uninit(&myDataBuffer1); // Refcount = 0. Unloaded. + ``` + +A binary search tree (BST) is used for storing data buffers as it has good balance between +efficiency and simplicity. The key of the BST is a 64-bit hash of the file path that was passed +into `ma_resource_manager_data_source_init()`. The advantage of using a hash is that it saves +memory over storing the entire path, has faster comparisons, and results in a mostly balanced BST +due to the random nature of the hash. The disadvantages are that file names are case-sensitive and +there's a small chance of name collisions. If case-sensitivity is an issue, you should normalize +your file names to upper- or lower-case before initializing your data sources. If name collisions +become an issue, you'll need to change the name of one of the colliding names or just not use the +resource manager. + +When a sound file has not already been loaded and the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_ASYNC` +flag is excluded, the file will be decoded synchronously by the calling thread. There are two +options for controlling how the audio is stored in the data buffer - encoded or decoded. When the +`MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_DECODE` option is excluded, the raw file data will be stored +in memory. Otherwise the sound will be decoded before storing it in memory. Synchronous loading is +a very simple and standard process of simply adding an item to the BST, allocating a block of +memory and then decoding (if `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_DECODE` is specified). + +When the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_ASYNC` flag is specified, loading of the data buffer +is done asynchronously. In this case, a job is posted to the queue to start loading and then the +function immediately returns, setting an internal result code to `MA_BUSY`. This result code is +returned when the program calls `ma_resource_manager_data_source_result()`. When decoding has fully +completed `MA_SUCCESS` will be returned. This can be used to know if loading has fully completed. + +When loading asynchronously, a single job is posted to the queue of the type +`MA_JOB_TYPE_RESOURCE_MANAGER_LOAD_DATA_BUFFER_NODE`. This involves making a copy of the file path and +associating it with job. When the job is processed by the job thread, it will first load the file +using the VFS associated with the resource manager. When using a custom VFS, it's important that it +be completely thread-safe because it will be used from one or more job threads at the same time. +Individual files should only ever be accessed by one thread at a time, however. After opening the +file via the VFS, the job will determine whether or not the file is being decoded. If not, it +simply allocates a block of memory and loads the raw file contents into it and returns. On the +other hand, when the file is being decoded, it will first allocate a decoder on the heap and +initialize it. Then it will check if the length of the file is known. If so it will allocate a +block of memory to store the decoded output and initialize it to silence. If the size is unknown, +it will allocate room for one page. After memory has been allocated, the first page will be +decoded. If the sound is shorter than a page, the result code will be set to `MA_SUCCESS` and the +completion event will be signalled and loading is now complete. If, however, there is more to +decode, a job with the code `MA_JOB_TYPE_RESOURCE_MANAGER_PAGE_DATA_BUFFER_NODE` is posted. This job +will decode the next page and perform the same process if it reaches the end. If there is more to +decode, the job will post another `MA_JOB_TYPE_RESOURCE_MANAGER_PAGE_DATA_BUFFER_NODE` job which will +keep on happening until the sound has been fully decoded. For sounds of an unknown length, each +page will be linked together as a linked list. Internally this is implemented via the +`ma_paged_audio_buffer` object. + + +6.2.3. Data Streams +------------------- +Data streams only ever store two pages worth of data for each instance. They are most useful for +large sounds like music tracks in games that would consume too much memory if fully decoded in +memory. After every frame from a page has been read, a job will be posted to load the next page +which is done from the VFS. + +For data streams, the `MA_RESOURCE_MANAGER_DATA_SOURCE_FLAG_ASYNC` flag will determine whether or +not initialization of the data source waits until the two pages have been decoded. When unset, +`ma_resource_manager_data_source_init()` will wait until the two pages have been loaded, otherwise +it will return immediately. + +When frames are read from a data stream using `ma_resource_manager_data_source_read_pcm_frames()`, +`MA_BUSY` will be returned if there are no frames available. If there are some frames available, +but less than the number requested, `MA_SUCCESS` will be returned, but the actual number of frames +read will be less than the number requested. Due to the asynchronous nature of data streams, +seeking is also asynchronous. If the data stream is in the middle of a seek, `MA_BUSY` will be +returned when trying to read frames. + +When `ma_resource_manager_data_source_read_pcm_frames()` results in a page getting fully consumed +a job is posted to load the next page. This will be posted from the same thread that called +`ma_resource_manager_data_source_read_pcm_frames()`. + +Data streams are uninitialized by posting a job to the queue, but the function won't return until +that job has been processed. The reason for this is that the caller owns the data stream object and +therefore miniaudio needs to ensure everything completes before handing back control to the caller. +Also, if the data stream is uninitialized while pages are in the middle of decoding, they must +complete before destroying any underlying object and the job system handles this cleanly. + +Note that when a new page needs to be loaded, a job will be posted to the resource manager's job +thread from the audio thread. You must keep in mind the details mentioned in the "Job Queue" +section above regarding locking when posting an event if you require a strictly lock-free audio +thread. + + + +7. Node Graph +============= +miniaudio's routing infrastructure follows a node graph paradigm. The idea is that you create a +node whose outputs are attached to inputs of another node, thereby creating a graph. There are +different types of nodes, with each node in the graph processing input data to produce output, +which is then fed through the chain. Each node in the graph can apply their own custom effects. At +the start of the graph will usually be one or more data source nodes which have no inputs and +instead pull their data from a data source. At the end of the graph is an endpoint which represents +the end of the chain and is where the final output is ultimately extracted from. + +Each node has a number of input buses and a number of output buses. An output bus from a node is +attached to an input bus of another. Multiple nodes can connect their output buses to another +node's input bus, in which case their outputs will be mixed before processing by the node. Below is +a diagram that illustrates a hypothetical node graph setup: + + ``` + >>>>>>>>>>>>>>>>>>>>>>>>>>>>>> Data flows left to right >>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> + + +---------------+ +-----------------+ + | Data Source 1 =----+ +----------+ +----= Low Pass Filter =----+ + +---------------+ | | =----+ +-----------------+ | +----------+ + +----= Splitter | +----= ENDPOINT | + +---------------+ | | =----+ +-----------------+ | +----------+ + | Data Source 2 =----+ +----------+ +----= Echo / Delay =----+ + +---------------+ +-----------------+ + ``` + +In the above graph, it starts with two data sources whose outputs are attached to the input of a +splitter node. It's at this point that the two data sources are mixed. After mixing, the splitter +performs it's processing routine and produces two outputs which is simply a duplication of the +input stream. One output is attached to a low pass filter, whereas the other output is attached to +a echo/delay. The outputs of the the low pass filter and the echo are attached to the endpoint, and +since they're both connected to the same input bus, they'll be mixed. + +Each input bus must be configured to accept the same number of channels, but the number of channels +used by input buses can be different to the number of channels for output buses in which case +miniaudio will automatically convert the input data to the output channel count before processing. +The number of channels of an output bus of one node must match the channel count of the input bus +it's attached to. The channel counts cannot be changed after the node has been initialized. If you +attempt to attach an output bus to an input bus with a different channel count, attachment will +fail. + +To use a node graph, you first need to initialize a `ma_node_graph` object. This is essentially a +container around the entire graph. The `ma_node_graph` object is required for some thread-safety +issues which will be explained later. A `ma_node_graph` object is initialized using miniaudio's +standard config/init system: + + ```c + ma_node_graph_config nodeGraphConfig = ma_node_graph_config_init(myChannelCount); + + result = ma_node_graph_init(&nodeGraphConfig, NULL, &nodeGraph); // Second parameter is a pointer to allocation callbacks. + if (result != MA_SUCCESS) { + // Failed to initialize node graph. + } + ``` + +When you initialize the node graph, you're specifying the channel count of the endpoint. The +endpoint is a special node which has one input bus and one output bus, both of which have the +same channel count, which is specified in the config. Any nodes that connect directly to the +endpoint must be configured such that their output buses have the same channel count. When you read +audio data from the node graph, it'll have the channel count you specified in the config. To read +data from the graph: + + ```c + ma_uint32 framesRead; + result = ma_node_graph_read_pcm_frames(&nodeGraph, pFramesOut, frameCount, &framesRead); + if (result != MA_SUCCESS) { + // Failed to read data from the node graph. + } + ``` + +When you read audio data, miniaudio starts at the node graph's endpoint node which then pulls in +data from it's input attachments, which in turn recursively pull in data from their inputs, and so +on. At the start of the graph there will be some kind of data source node which will have zero +inputs and will instead read directly from a data source. The base nodes don't literally need to +read from a `ma_data_source` object, but they will always have some kind of underlying object that +sources some kind of audio. The `ma_data_source_node` node can be used to read from a +`ma_data_source`. Data is always in floating-point format and in the number of channels you +specified when the graph was initialized. The sample rate is defined by the underlying data sources. +It's up to you to ensure they use a consistent and appropriate sample rate. + +The `ma_node` API is designed to allow custom nodes to be implemented with relative ease, but +miniaudio includes a few stock nodes for common functionality. This is how you would initialize a +node which reads directly from a data source (`ma_data_source_node`) which is an example of one +of the stock nodes that comes with miniaudio: + + ```c + ma_data_source_node_config config = ma_data_source_node_config_init(pMyDataSource); + + ma_data_source_node dataSourceNode; + result = ma_data_source_node_init(&nodeGraph, &config, NULL, &dataSourceNode); + if (result != MA_SUCCESS) { + // Failed to create data source node. + } + ``` + +The data source node will use the output channel count to determine the channel count of the output +bus. There will be 1 output bus and 0 input buses (data will be drawn directly from the data +source). The data source must output to floating-point (`ma_format_f32`) or else an error will be +returned from `ma_data_source_node_init()`. + +By default the node will not be attached to the graph. To do so, use `ma_node_attach_output_bus()`: + + ```c + result = ma_node_attach_output_bus(&dataSourceNode, 0, ma_node_graph_get_endpoint(&nodeGraph), 0); + if (result != MA_SUCCESS) { + // Failed to attach node. + } + ``` + +The code above connects the data source node directly to the endpoint. Since the data source node +has only a single output bus, the index will always be 0. Likewise, the endpoint only has a single +input bus which means the input bus index will also always be 0. + +To detach a specific output bus, use `ma_node_detach_output_bus()`. To detach all output buses, use +`ma_node_detach_all_output_buses()`. If you want to just move the output bus from one attachment to +another, you do not need to detach first. You can just call `ma_node_attach_output_bus()` and it'll +deal with it for you. + +Less frequently you may want to create a specialized node. This will be a node where you implement +your own processing callback to apply a custom effect of some kind. This is similar to initializing +one of the stock node types, only this time you need to specify a pointer to a vtable containing a +pointer to the processing function and the number of input and output buses. Example: + + ```c + static void my_custom_node_process_pcm_frames(ma_node* pNode, const float** ppFramesIn, ma_uint32* pFrameCountIn, float** ppFramesOut, ma_uint32* pFrameCountOut) + { + // Do some processing of ppFramesIn (one stream of audio data per input bus) + const float* pFramesIn_0 = ppFramesIn[0]; // Input bus @ index 0. + const float* pFramesIn_1 = ppFramesIn[1]; // Input bus @ index 1. + float* pFramesOut_0 = ppFramesOut[0]; // Output bus @ index 0. + + // Do some processing. On input, `pFrameCountIn` will be the number of input frames in each + // buffer in `ppFramesIn` and `pFrameCountOut` will be the capacity of each of the buffers + // in `ppFramesOut`. On output, `pFrameCountIn` should be set to the number of input frames + // your node consumed and `pFrameCountOut` should be set the number of output frames that + // were produced. + // + // You should process as many frames as you can. If your effect consumes input frames at the + // same rate as output frames (always the case, unless you're doing resampling), you need + // only look at `ppFramesOut` and process that exact number of frames. If you're doing + // resampling, you'll need to be sure to set both `pFrameCountIn` and `pFrameCountOut` + // properly. + } + + static ma_node_vtable my_custom_node_vtable = + { + my_custom_node_process_pcm_frames, // The function that will be called to process your custom node. This is where you'd implement your effect processing. + NULL, // Optional. A callback for calculating the number of input frames that are required to process a specified number of output frames. + 2, // 2 input buses. + 1, // 1 output bus. + 0 // Default flags. + }; + + ... + + // Each bus needs to have a channel count specified. To do this you need to specify the channel + // counts in an array and then pass that into the node config. + ma_uint32 inputChannels[2]; // Equal in size to the number of input channels specified in the vtable. + ma_uint32 outputChannels[1]; // Equal in size to the number of output channels specified in the vtable. + + inputChannels[0] = channelsIn; + inputChannels[1] = channelsIn; + outputChannels[0] = channelsOut; + + ma_node_config nodeConfig = ma_node_config_init(); + nodeConfig.vtable = &my_custom_node_vtable; + nodeConfig.pInputChannels = inputChannels; + nodeConfig.pOutputChannels = outputChannels; + + ma_node_base node; + result = ma_node_init(&nodeGraph, &nodeConfig, NULL, &node); + if (result != MA_SUCCESS) { + // Failed to initialize node. + } + ``` + +When initializing a custom node, as in the code above, you'll normally just place your vtable in +static space. The number of input and output buses are specified as part of the vtable. If you need +a variable number of buses on a per-node bases, the vtable should have the relevant bus count set +to `MA_NODE_BUS_COUNT_UNKNOWN`. In this case, the bus count should be set in the node config: + + ```c + static ma_node_vtable my_custom_node_vtable = + { + my_custom_node_process_pcm_frames, // The function that will be called process your custom node. This is where you'd implement your effect processing. + NULL, // Optional. A callback for calculating the number of input frames that are required to process a specified number of output frames. + MA_NODE_BUS_COUNT_UNKNOWN, // The number of input buses is determined on a per-node basis. + 1, // 1 output bus. + 0 // Default flags. + }; + + ... + + ma_node_config nodeConfig = ma_node_config_init(); + nodeConfig.vtable = &my_custom_node_vtable; + nodeConfig.inputBusCount = myBusCount; // <-- Since the vtable specifies MA_NODE_BUS_COUNT_UNKNOWN, the input bus count should be set here. + nodeConfig.pInputChannels = inputChannels; // <-- Make sure there are nodeConfig.inputBusCount elements in this array. + nodeConfig.pOutputChannels = outputChannels; // <-- The vtable specifies 1 output bus, so there must be 1 element in this array. + ``` + +In the above example it's important to never set the `inputBusCount` and `outputBusCount` members +to anything other than their defaults if the vtable specifies an explicit count. They can only be +set if the vtable specifies MA_NODE_BUS_COUNT_UNKNOWN in the relevant bus count. + +Most often you'll want to create a structure to encapsulate your node with some extra data. You +need to make sure the `ma_node_base` object is your first member of the structure: + + ```c + typedef struct + { + ma_node_base base; // <-- Make sure this is always the first member. + float someCustomData; + } my_custom_node; + ``` + +By doing this, your object will be compatible with all `ma_node` APIs and you can attach it to the +graph just like any other node. + +In the custom processing callback (`my_custom_node_process_pcm_frames()` in the example above), the +number of channels for each bus is what was specified by the config when the node was initialized +with `ma_node_init()`. In addition, all attachments to each of the input buses will have been +pre-mixed by miniaudio. The config allows you to specify different channel counts for each +individual input and output bus. It's up to the effect to handle it appropriate, and if it can't, +return an error in it's initialization routine. + +Custom nodes can be assigned some flags to describe their behaviour. These are set via the vtable +and include the following: + + +-----------------------------------------+---------------------------------------------------+ + | Flag Name | Description | + +-----------------------------------------+---------------------------------------------------+ + | MA_NODE_FLAG_PASSTHROUGH | Useful for nodes that do not do any kind of audio | + | | processing, but are instead used for tracking | + | | time, handling events, etc. Also used by the | + | | internal endpoint node. It reads directly from | + | | the input bus to the output bus. Nodes with this | + | | flag must have exactly 1 input bus and 1 output | + | | bus, and both buses must have the same channel | + | | counts. | + +-----------------------------------------+---------------------------------------------------+ + | MA_NODE_FLAG_CONTINUOUS_PROCESSING | Causes the processing callback to be called even | + | | when no data is available to be read from input | + | | attachments. When a node has at least one input | + | | bus, but there are no inputs attached or the | + | | inputs do not deliver any data, the node's | + | | processing callback will not get fired. This flag | + | | will make it so the callback is always fired | + | | regardless of whether or not any input data is | + | | received. This is useful for effects like | + | | echos where there will be a tail of audio data | + | | that still needs to be processed even when the | + | | original data sources have reached their ends. It | + | | may also be useful for nodes that must always | + | | have their processing callback fired when there | + | | are no inputs attached. | + +-----------------------------------------+---------------------------------------------------+ + | MA_NODE_FLAG_ALLOW_NULL_INPUT | Used in conjunction with | + | | `MA_NODE_FLAG_CONTINUOUS_PROCESSING`. When this | + | | is set, the `ppFramesIn` parameter of the | + | | processing callback will be set to NULL when | + | | there are no input frames are available. When | + | | this is unset, silence will be posted to the | + | | processing callback. | + +-----------------------------------------+---------------------------------------------------+ + | MA_NODE_FLAG_DIFFERENT_PROCESSING_RATES | Used to tell miniaudio that input and output | + | | frames are processed at different rates. You | + | | should set this for any nodes that perform | + | | resampling. | + +-----------------------------------------+---------------------------------------------------+ + | MA_NODE_FLAG_SILENT_OUTPUT | Used to tell miniaudio that a node produces only | + | | silent output. This is useful for nodes where you | + | | don't want the output to contribute to the final | + | | mix. An example might be if you want split your | + | | stream and have one branch be output to a file. | + | | When using this flag, you should avoid writing to | + | | the output buffer of the node's processing | + | | callback because miniaudio will ignore it anyway. | + +-----------------------------------------+---------------------------------------------------+ + + +If you need to make a copy of an audio stream for effect processing you can use a splitter node +called `ma_splitter_node`. This takes has 1 input bus and splits the stream into 2 output buses. +You can use it like this: + + ```c + ma_splitter_node_config splitterNodeConfig = ma_splitter_node_config_init(channels); + + ma_splitter_node splitterNode; + result = ma_splitter_node_init(&nodeGraph, &splitterNodeConfig, NULL, &splitterNode); + if (result != MA_SUCCESS) { + // Failed to create node. + } + + // Attach your output buses to two different input buses (can be on two different nodes). + ma_node_attach_output_bus(&splitterNode, 0, ma_node_graph_get_endpoint(&nodeGraph), 0); // Attach directly to the endpoint. + ma_node_attach_output_bus(&splitterNode, 1, &myEffectNode, 0); // Attach to input bus 0 of some effect node. + ``` + +The volume of an output bus can be configured on a per-bus basis: + + ```c + ma_node_set_output_bus_volume(&splitterNode, 0, 0.5f); + ma_node_set_output_bus_volume(&splitterNode, 1, 0.5f); + ``` + +In the code above we're using the splitter node from before and changing the volume of each of the +copied streams. + +You can start and stop a node with the following: + + ```c + ma_node_set_state(&splitterNode, ma_node_state_started); // The default state. + ma_node_set_state(&splitterNode, ma_node_state_stopped); + ``` + +By default the node is in a started state, but since it won't be connected to anything won't +actually be invoked by the node graph until it's connected. When you stop a node, data will not be +read from any of it's input connections. You can use this property to stop a group of sounds +atomically. + +You can configure the initial state of a node in it's config: + + ```c + nodeConfig.initialState = ma_node_state_stopped; + ``` + +Note that for the stock specialized nodes, all of their configs will have a `nodeConfig` member +which is the config to use with the base node. This is where the initial state can be configured +for specialized nodes: + + ```c + dataSourceNodeConfig.nodeConfig.initialState = ma_node_state_stopped; + ``` + +When using a specialized node like `ma_data_source_node` or `ma_splitter_node`, be sure to not +modify the `vtable` member of the `nodeConfig` object. + + +7.1. Timing +----------- +The node graph supports starting and stopping nodes at scheduled times. This is especially useful +for data source nodes where you want to get the node set up, but only start playback at a specific +time. There are two clocks: local and global. + +A local clock is per-node, whereas the global clock is per graph. Scheduling starts and stops can +only be done based on the global clock because the local clock will not be running while the node +is stopped. The global clocks advances whenever `ma_node_graph_read_pcm_frames()` is called. On the +other hand, the local clock only advances when the node's processing callback is fired, and is +advanced based on the output frame count. + +To retrieve the global time, use `ma_node_graph_get_time()`. The global time can be set with +`ma_node_graph_set_time()` which might be useful if you want to do seeking on a global timeline. +Getting and setting the local time is similar. Use `ma_node_get_time()` to retrieve the local time, +and `ma_node_set_time()` to set the local time. The global and local times will be advanced by the +audio thread, so care should be taken to avoid data races. Ideally you should avoid calling these +outside of the node processing callbacks which are always run on the audio thread. + +There is basic support for scheduling the starting and stopping of nodes. You can only schedule one +start and one stop at a time. This is mainly intended for putting nodes into a started or stopped +state in a frame-exact manner. Without this mechanism, starting and stopping of a node is limited +to the resolution of a call to `ma_node_graph_read_pcm_frames()` which would typically be in blocks +of several milliseconds. The following APIs can be used for scheduling node states: + + ```c + ma_node_set_state_time() + ma_node_get_state_time() + ``` + +The time is absolute and must be based on the global clock. An example is below: + + ```c + ma_node_set_state_time(&myNode, ma_node_state_started, sampleRate*1); // Delay starting to 1 second. + ma_node_set_state_time(&myNode, ma_node_state_stopped, sampleRate*5); // Delay stopping to 5 seconds. + ``` + +An example for changing the state using a relative time. + + ```c + ma_node_set_state_time(&myNode, ma_node_state_started, sampleRate*1 + ma_node_graph_get_time(&myNodeGraph)); + ma_node_set_state_time(&myNode, ma_node_state_stopped, sampleRate*5 + ma_node_graph_get_time(&myNodeGraph)); + ``` + +Note that due to the nature of multi-threading the times may not be 100% exact. If this is an +issue, consider scheduling state changes from within a processing callback. An idea might be to +have some kind of passthrough trigger node that is used specifically for tracking time and handling +events. + + + +7.2. Thread Safety and Locking +------------------------------ +When processing audio, it's ideal not to have any kind of locking in the audio thread. Since it's +expected that `ma_node_graph_read_pcm_frames()` would be run on the audio thread, it does so +without the use of any locks. This section discusses the implementation used by miniaudio and goes +over some of the compromises employed by miniaudio to achieve this goal. Note that the current +implementation may not be ideal - feedback and critiques are most welcome. + +The node graph API is not *entirely* lock-free. Only `ma_node_graph_read_pcm_frames()` is expected +to be lock-free. Attachment, detachment and uninitialization of nodes use locks to simplify the +implementation, but are crafted in a way such that such locking is not required when reading audio +data from the graph. Locking in these areas are achieved by means of spinlocks. + +The main complication with keeping `ma_node_graph_read_pcm_frames()` lock-free stems from the fact +that a node can be uninitialized, and it's memory potentially freed, while in the middle of being +processed on the audio thread. There are times when the audio thread will be referencing a node, +which means the uninitialization process of a node needs to make sure it delays returning until the +audio thread is finished so that control is not handed back to the caller thereby giving them a +chance to free the node's memory. + +When the audio thread is processing a node, it does so by reading from each of the output buses of +the node. In order for a node to process data for one of it's output buses, it needs to read from +each of it's input buses, and so on an so forth. It follows that once all output buses of a node +are detached, the node as a whole will be disconnected and no further processing will occur unless +it's output buses are reattached, which won't be happening when the node is being uninitialized. +By having `ma_node_detach_output_bus()` wait until the audio thread is finished with it, we can +simplify a few things, at the expense of making `ma_node_detach_output_bus()` a bit slower. By +doing this, the implementation of `ma_node_uninit()` becomes trivial - just detach all output +nodes, followed by each of the attachments to each of it's input nodes, and then do any final clean +up. + +With the above design, the worst-case scenario is `ma_node_detach_output_bus()` taking as long as +it takes to process the output bus being detached. This will happen if it's called at just the +wrong moment where the audio thread has just iterated it and has just started processing. The +caller of `ma_node_detach_output_bus()` will stall until the audio thread is finished, which +includes the cost of recursively processing it's inputs. This is the biggest compromise made with +the approach taken by miniaudio for it's lock-free processing system. The cost of detaching nodes +earlier in the pipeline (data sources, for example) will be cheaper than the cost of detaching +higher level nodes, such as some kind of final post-processing endpoint. If you need to do mass +detachments, detach starting from the lowest level nodes and work your way towards the final +endpoint node (but don't try detaching the node graph's endpoint). If the audio thread is not +running, detachment will be fast and detachment in any order will be the same. The reason nodes +need to wait for their input attachments to complete is due to the potential for desyncs between +data sources. If the node was to terminate processing mid way through processing it's inputs, +there's a chance that some of the underlying data sources will have been read, but then others not. +That will then result in a potential desynchronization when detaching and reattaching higher-level +nodes. A possible solution to this is to have an option when detaching to terminate processing +before processing all input attachments which should be fairly simple. + +Another compromise, albeit less significant, is locking when attaching and detaching nodes. This +locking is achieved by means of a spinlock in order to reduce memory overhead. A lock is present +for each input bus and output bus. When an output bus is connected to an input bus, both the output +bus and input bus is locked. This locking is specifically for attaching and detaching across +different threads and does not affect `ma_node_graph_read_pcm_frames()` in any way. The locking and +unlocking is mostly self-explanatory, but a slightly less intuitive aspect comes into it when +considering that iterating over attachments must not break as a result of attaching or detaching a +node while iteration is occurring. + +Attaching and detaching are both quite simple. When an output bus of a node is attached to an input +bus of another node, it's added to a linked list. Basically, an input bus is a linked list, where +each item in the list is and output bus. We have some intentional (and convenient) restrictions on +what can done with the linked list in order to simplify the implementation. First of all, whenever +something needs to iterate over the list, it must do so in a forward direction. Backwards iteration +is not supported. Also, items can only be added to the start of the list. + +The linked list is a doubly-linked list where each item in the list (an output bus) holds a pointer +to the next item in the list, and another to the previous item. A pointer to the previous item is +only required for fast detachment of the node - it is never used in iteration. This is an +important property because it means from the perspective of iteration, attaching and detaching of +an item can be done with a single atomic assignment. This is exploited by both the attachment and +detachment process. When attaching the node, the first thing that is done is the setting of the +local "next" and "previous" pointers of the node. After that, the item is "attached" to the list +by simply performing an atomic exchange with the head pointer. After that, the node is "attached" +to the list from the perspective of iteration. Even though the "previous" pointer of the next item +hasn't yet been set, from the perspective of iteration it's been attached because iteration will +only be happening in a forward direction which means the "previous" pointer won't actually ever get +used. The same general process applies to detachment. See `ma_node_attach_output_bus()` and +`ma_node_detach_output_bus()` for the implementation of this mechanism. + + + +8. Decoding +=========== +The `ma_decoder` API is used for reading audio files. Decoders are completely decoupled from +devices and can be used independently. Built-in support is included for the following formats: + + +---------+ + | Format | + +---------+ + | WAV | + | MP3 | + | FLAC | + +---------+ + +You can disable the built-in decoders by specifying one or more of the following options before the +miniaudio implementation: + + ```c + #define MA_NO_WAV + #define MA_NO_MP3 + #define MA_NO_FLAC + ``` + +miniaudio supports the ability to plug in custom decoders. See the section below for details on how +to use custom decoders. + +A decoder can be initialized from a file with `ma_decoder_init_file()`, a block of memory with +`ma_decoder_init_memory()`, or from data delivered via callbacks with `ma_decoder_init()`. Here is +an example for loading a decoder from a file: + + ```c + ma_decoder decoder; + ma_result result = ma_decoder_init_file("MySong.mp3", NULL, &decoder); + if (result != MA_SUCCESS) { + return false; // An error occurred. + } + + ... + + ma_decoder_uninit(&decoder); + ``` + +When initializing a decoder, you can optionally pass in a pointer to a `ma_decoder_config` object +(the `NULL` argument in the example above) which allows you to configure the output format, channel +count, sample rate and channel map: + + ```c + ma_decoder_config config = ma_decoder_config_init(ma_format_f32, 2, 48000); + ``` + +When passing in `NULL` for decoder config in `ma_decoder_init*()`, the output format will be the +same as that defined by the decoding backend. + +Data is read from the decoder as PCM frames. This will output the number of PCM frames actually +read. If this is less than the requested number of PCM frames it means you've reached the end. The +return value will be `MA_AT_END` if no samples have been read and the end has been reached. + + ```c + ma_result result = ma_decoder_read_pcm_frames(pDecoder, pFrames, framesToRead, &framesRead); + if (framesRead < framesToRead) { + // Reached the end. + } + ``` + +You can also seek to a specific frame like so: + + ```c + ma_result result = ma_decoder_seek_to_pcm_frame(pDecoder, targetFrame); + if (result != MA_SUCCESS) { + return false; // An error occurred. + } + ``` + +If you want to loop back to the start, you can simply seek back to the first PCM frame: + + ```c + ma_decoder_seek_to_pcm_frame(pDecoder, 0); + ``` + +When loading a decoder, miniaudio uses a trial and error technique to find the appropriate decoding +backend. This can be unnecessarily inefficient if the type is already known. In this case you can +use `encodingFormat` variable in the device config to specify a specific encoding format you want +to decode: + + ```c + decoderConfig.encodingFormat = ma_encoding_format_wav; + ``` + +See the `ma_encoding_format` enum for possible encoding formats. + +The `ma_decoder_init_file()` API will try using the file extension to determine which decoding +backend to prefer. + + +8.1. Custom Decoders +-------------------- +It's possible to implement a custom decoder and plug it into miniaudio. This is extremely useful +when you want to use the `ma_decoder` API, but need to support an encoding format that's not one of +the stock formats supported by miniaudio. This can be put to particularly good use when using the +`ma_engine` and/or `ma_resource_manager` APIs because they use `ma_decoder` internally. If, for +example, you wanted to support Opus, you can do so with a custom decoder (there if a reference +Opus decoder in the "extras" folder of the miniaudio repository which uses libopus + libopusfile). + +A custom decoder must implement a data source. A vtable called `ma_decoding_backend_vtable` needs +to be implemented which is then passed into the decoder config: + + ```c + ma_decoding_backend_vtable* pCustomBackendVTables[] = + { + &g_ma_decoding_backend_vtable_libvorbis, + &g_ma_decoding_backend_vtable_libopus + }; + + ... + + decoderConfig = ma_decoder_config_init_default(); + decoderConfig.pCustomBackendUserData = NULL; + decoderConfig.ppCustomBackendVTables = pCustomBackendVTables; + decoderConfig.customBackendCount = sizeof(pCustomBackendVTables) / sizeof(pCustomBackendVTables[0]); + ``` + +The `ma_decoding_backend_vtable` vtable has the following functions: + + ``` + onInit + onInitFile + onInitFileW + onInitMemory + onUninit + ``` + +There are only two functions that must be implemented - `onInit` and `onUninit`. The other +functions can be implemented for a small optimization for loading from a file path or memory. If +these are not specified, miniaudio will deal with it for you via a generic implementation. + +When you initialize a custom data source (by implementing the `onInit` function in the vtable) you +will need to output a pointer to a `ma_data_source` which implements your custom decoder. See the +section about data sources for details on how to implement this. Alternatively, see the +"custom_decoders" example in the miniaudio repository. + +The `onInit` function takes a pointer to some callbacks for the purpose of reading raw audio data +from some arbitrary source. You'll use these functions to read from the raw data and perform the +decoding. When you call them, you will pass in the `pReadSeekTellUserData` pointer to the relevant +parameter. + +The `pConfig` parameter in `onInit` can be used to configure the backend if appropriate. It's only +used as a hint and can be ignored. However, if any of the properties are relevant to your decoder, +an optimal implementation will handle the relevant properties appropriately. + +If memory allocation is required, it should be done so via the specified allocation callbacks if +possible (the `pAllocationCallbacks` parameter). + +If an error occurs when initializing the decoder, you should leave `ppBackend` unset, or set to +NULL, and make sure everything is cleaned up appropriately and an appropriate result code returned. +When multiple custom backends are specified, miniaudio will cycle through the vtables in the order +they're listed in the array that's passed into the decoder config so it's important that your +initialization routine is clean. + +When a decoder is uninitialized, the `onUninit` callback will be fired which will give you an +opportunity to clean up and internal data. + + + +9. Encoding +=========== +The `ma_encoding` API is used for writing audio files. The only supported output format is WAV. +This can be disabled by specifying the following option before the implementation of miniaudio: + + ```c + #define MA_NO_WAV + ``` + +An encoder can be initialized to write to a file with `ma_encoder_init_file()` or from data +delivered via callbacks with `ma_encoder_init()`. Below is an example for initializing an encoder +to output to a file. + + ```c + ma_encoder_config config = ma_encoder_config_init(ma_encoding_format_wav, FORMAT, CHANNELS, SAMPLE_RATE); + ma_encoder encoder; + ma_result result = ma_encoder_init_file("my_file.wav", &config, &encoder); + if (result != MA_SUCCESS) { + // Error + } + + ... + + ma_encoder_uninit(&encoder); + ``` + +When initializing an encoder you must specify a config which is initialized with +`ma_encoder_config_init()`. Here you must specify the file type, the output sample format, output +channel count and output sample rate. The following file types are supported: + + +------------------------+-------------+ + | Enum | Description | + +------------------------+-------------+ + | ma_encoding_format_wav | WAV | + +------------------------+-------------+ + +If the format, channel count or sample rate is not supported by the output file type an error will +be returned. The encoder will not perform data conversion so you will need to convert it before +outputting any audio data. To output audio data, use `ma_encoder_write_pcm_frames()`, like in the +example below: + + ```c + ma_uint64 framesWritten; + result = ma_encoder_write_pcm_frames(&encoder, pPCMFramesToWrite, framesToWrite, &framesWritten); + if (result != MA_SUCCESS) { + ... handle error ... + } + ``` + +The `framesWritten` variable will contain the number of PCM frames that were actually written. This +is optionally and you can pass in `NULL` if you need this. + +Encoders must be uninitialized with `ma_encoder_uninit()`. + + + +10. Data Conversion +=================== +A data conversion API is included with miniaudio which supports the majority of data conversion +requirements. This supports conversion between sample formats, channel counts (with channel +mapping) and sample rates. + + +10.1. Sample Format Conversion +------------------------------ +Conversion between sample formats is achieved with the `ma_pcm_*_to_*()`, `ma_pcm_convert()` and +`ma_convert_pcm_frames_format()` APIs. Use `ma_pcm_*_to_*()` to convert between two specific +formats. Use `ma_pcm_convert()` to convert based on a `ma_format` variable. Use +`ma_convert_pcm_frames_format()` to convert PCM frames where you want to specify the frame count +and channel count as a variable instead of the total sample count. + + +10.1.1. Dithering +----------------- +Dithering can be set using the ditherMode parameter. + +The different dithering modes include the following, in order of efficiency: + + +-----------+--------------------------+ + | Type | Enum Token | + +-----------+--------------------------+ + | None | ma_dither_mode_none | + | Rectangle | ma_dither_mode_rectangle | + | Triangle | ma_dither_mode_triangle | + +-----------+--------------------------+ + +Note that even if the dither mode is set to something other than `ma_dither_mode_none`, it will be +ignored for conversions where dithering is not needed. Dithering is available for the following +conversions: + + ``` + s16 -> u8 + s24 -> u8 + s32 -> u8 + f32 -> u8 + s24 -> s16 + s32 -> s16 + f32 -> s16 + ``` + +Note that it is not an error to pass something other than ma_dither_mode_none for conversions where +dither is not used. It will just be ignored. + + + +10.2. Channel Conversion +------------------------ +Channel conversion is used for channel rearrangement and conversion from one channel count to +another. The `ma_channel_converter` API is used for channel conversion. Below is an example of +initializing a simple channel converter which converts from mono to stereo. + + ```c + ma_channel_converter_config config = ma_channel_converter_config_init( + ma_format, // Sample format + 1, // Input channels + NULL, // Input channel map + 2, // Output channels + NULL, // Output channel map + ma_channel_mix_mode_default); // The mixing algorithm to use when combining channels. + + result = ma_channel_converter_init(&config, NULL, &converter); + if (result != MA_SUCCESS) { + // Error. + } + ``` + +To perform the conversion simply call `ma_channel_converter_process_pcm_frames()` like so: + + ```c + ma_result result = ma_channel_converter_process_pcm_frames(&converter, pFramesOut, pFramesIn, frameCount); + if (result != MA_SUCCESS) { + // Error. + } + ``` + +It is up to the caller to ensure the output buffer is large enough to accommodate the new PCM +frames. + +Input and output PCM frames are always interleaved. Deinterleaved layouts are not supported. + + +10.2.1. Channel Mapping +----------------------- +In addition to converting from one channel count to another, like the example above, the channel +converter can also be used to rearrange channels. When initializing the channel converter, you can +optionally pass in channel maps for both the input and output frames. If the channel counts are the +same, and each channel map contains the same channel positions with the exception that they're in +a different order, a simple shuffling of the channels will be performed. If, however, there is not +a 1:1 mapping of channel positions, or the channel counts differ, the input channels will be mixed +based on a mixing mode which is specified when initializing the `ma_channel_converter_config` +object. + +When converting from mono to multi-channel, the mono channel is simply copied to each output +channel. When going the other way around, the audio of each output channel is simply averaged and +copied to the mono channel. + +In more complicated cases blending is used. The `ma_channel_mix_mode_simple` mode will drop excess +channels and silence extra channels. For example, converting from 4 to 2 channels, the 3rd and 4th +channels will be dropped, whereas converting from 2 to 4 channels will put silence into the 3rd and +4th channels. + +The `ma_channel_mix_mode_rectangle` mode uses spacial locality based on a rectangle to compute a +simple distribution between input and output. Imagine sitting in the middle of a room, with +speakers on the walls representing channel positions. The `MA_CHANNEL_FRONT_LEFT` position can be +thought of as being in the corner of the front and left walls. + +Finally, the `ma_channel_mix_mode_custom_weights` mode can be used to use custom user-defined +weights. Custom weights can be passed in as the last parameter of +`ma_channel_converter_config_init()`. + +Predefined channel maps can be retrieved with `ma_channel_map_init_standard()`. This takes a +`ma_standard_channel_map` enum as it's first parameter, which can be one of the following: + + +-----------------------------------+-----------------------------------------------------------+ + | Name | Description | + +-----------------------------------+-----------------------------------------------------------+ + | ma_standard_channel_map_default | Default channel map used by miniaudio.

This | + | | is equivalent to the same | + | | mapping as the device. | + +---------------+---------------------------------+ + + + +10.3. Resampling +---------------- +Resampling is achieved with the `ma_resampler` object. To create a resampler object, do something +like the following: + + ```c + ma_resampler_config config = ma_resampler_config_init( + ma_format_s16, + channels, + sampleRateIn, + sampleRateOut, + ma_resample_algorithm_linear); + + ma_resampler resampler; + ma_result result = ma_resampler_init(&config, &resampler); + if (result != MA_SUCCESS) { + // An error occurred... + } + ``` + +Do the following to uninitialize the resampler: + + ```c + ma_resampler_uninit(&resampler); + ``` + +The following example shows how data can be processed + + ```c + ma_uint64 frameCountIn = 1000; + ma_uint64 frameCountOut = 2000; + ma_result result = ma_resampler_process_pcm_frames(&resampler, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut); + if (result != MA_SUCCESS) { + // An error occurred... + } + + // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the + // number of output frames written. + ``` + +To initialize the resampler you first need to set up a config (`ma_resampler_config`) with +`ma_resampler_config_init()`. You need to specify the sample format you want to use, the number of +channels, the input and output sample rate, and the algorithm. + +The sample format can be either `ma_format_s16` or `ma_format_f32`. If you need a different format +you will need to perform pre- and post-conversions yourself where necessary. Note that the format +is the same for both input and output. The format cannot be changed after initialization. + +The resampler supports multiple channels and is always interleaved (both input and output). The +channel count cannot be changed after initialization. + +The sample rates can be anything other than zero, and are always specified in hertz. They should be +set to something like 44100, etc. The sample rate is the only configuration property that can be +changed after initialization. + +The miniaudio resampler has built-in support for the following algorithms: + + +-----------+------------------------------+ + | Algorithm | Enum Token | + +-----------+------------------------------+ + | Linear | ma_resample_algorithm_linear | + | Custom | ma_resample_algorithm_custom | + +-----------+------------------------------+ + +The algorithm cannot be changed after initialization. + +Processing always happens on a per PCM frame basis and always assumes interleaved input and output. +De-interleaved processing is not supported. To process frames, use +`ma_resampler_process_pcm_frames()`. On input, this function takes the number of output frames you +can fit in the output buffer and the number of input frames contained in the input buffer. On +output these variables contain the number of output frames that were written to the output buffer +and the number of input frames that were consumed in the process. You can pass in NULL for the +input buffer in which case it will be treated as an infinitely large buffer of zeros. The output +buffer can also be NULL, in which case the processing will be treated as seek. + +The sample rate can be changed dynamically on the fly. You can change this with explicit sample +rates with `ma_resampler_set_rate()` and also with a decimal ratio with +`ma_resampler_set_rate_ratio()`. The ratio is in/out. + +Sometimes it's useful to know exactly how many input frames will be required to output a specific +number of frames. You can calculate this with `ma_resampler_get_required_input_frame_count()`. +Likewise, it's sometimes useful to know exactly how many frames would be output given a certain +number of input frames. You can do this with `ma_resampler_get_expected_output_frame_count()`. + +Due to the nature of how resampling works, the resampler introduces some latency. This can be +retrieved in terms of both the input rate and the output rate with +`ma_resampler_get_input_latency()` and `ma_resampler_get_output_latency()`. + + +10.3.1. Resampling Algorithms +----------------------------- +The choice of resampling algorithm depends on your situation and requirements. + + +10.3.1.1. Linear Resampling +--------------------------- +The linear resampler is the fastest, but comes at the expense of poorer quality. There is, however, +some control over the quality of the linear resampler which may make it a suitable option depending +on your requirements. + +The linear resampler performs low-pass filtering before or after downsampling or upsampling, +depending on the sample rates you're converting between. When decreasing the sample rate, the +low-pass filter will be applied before downsampling. When increasing the rate it will be performed +after upsampling. By default a fourth order low-pass filter will be applied. This can be configured +via the `lpfOrder` configuration variable. Setting this to 0 will disable filtering. + +The low-pass filter has a cutoff frequency which defaults to half the sample rate of the lowest of +the input and output sample rates (Nyquist Frequency). + +The API for the linear resampler is the same as the main resampler API, only it's called +`ma_linear_resampler`. + + +10.3.2. Custom Resamplers +------------------------- +You can implement a custom resampler by using the `ma_resample_algorithm_custom` resampling +algorithm and setting a vtable in the resampler config: + + ```c + ma_resampler_config config = ma_resampler_config_init(..., ma_resample_algorithm_custom); + config.pBackendVTable = &g_customResamplerVTable; + ``` + +Custom resamplers are useful if the stock algorithms are not appropriate for your use case. You +need to implement the required functions in `ma_resampling_backend_vtable`. Note that not all +functions in the vtable need to be implemented, but if it's possible to implement, they should be. + +You can use the `ma_linear_resampler` object for an example on how to implement the vtable. The +`onGetHeapSize` callback is used to calculate the size of any internal heap allocation the custom +resampler will need to make given the supplied config. When you initialize the resampler via the +`onInit` callback, you'll be given a pointer to a heap allocation which is where you should store +the heap allocated data. You should not free this data in `onUninit` because miniaudio will manage +it for you. + +The `onProcess` callback is where the actual resampling takes place. On input, `pFrameCountIn` +points to a variable containing the number of frames in the `pFramesIn` buffer and +`pFrameCountOut` points to a variable containing the capacity in frames of the `pFramesOut` buffer. +On output, `pFrameCountIn` should be set to the number of input frames that were fully consumed, +whereas `pFrameCountOut` should be set to the number of frames that were written to `pFramesOut`. + +The `onSetRate` callback is optional and is used for dynamically changing the sample rate. If +dynamic rate changes are not supported, you can set this callback to NULL. + +The `onGetInputLatency` and `onGetOutputLatency` functions are used for retrieving the latency in +input and output rates respectively. These can be NULL in which case latency calculations will be +assumed to be NULL. + +The `onGetRequiredInputFrameCount` callback is used to give miniaudio a hint as to how many input +frames are required to be available to produce the given number of output frames. Likewise, the +`onGetExpectedOutputFrameCount` callback is used to determine how many output frames will be +produced given the specified number of input frames. miniaudio will use these as a hint, but they +are optional and can be set to NULL if you're unable to implement them. + + + +10.4. General Data Conversion +----------------------------- +The `ma_data_converter` API can be used to wrap sample format conversion, channel conversion and +resampling into one operation. This is what miniaudio uses internally to convert between the format +requested when the device was initialized and the format of the backend's native device. The API +for general data conversion is very similar to the resampling API. Create a `ma_data_converter` +object like this: + + ```c + ma_data_converter_config config = ma_data_converter_config_init( + inputFormat, + outputFormat, + inputChannels, + outputChannels, + inputSampleRate, + outputSampleRate + ); + + ma_data_converter converter; + ma_result result = ma_data_converter_init(&config, NULL, &converter); + if (result != MA_SUCCESS) { + // An error occurred... + } + ``` + +In the example above we use `ma_data_converter_config_init()` to initialize the config, however +there's many more properties that can be configured, such as channel maps and resampling quality. +Something like the following may be more suitable depending on your requirements: + + ```c + ma_data_converter_config config = ma_data_converter_config_init_default(); + config.formatIn = inputFormat; + config.formatOut = outputFormat; + config.channelsIn = inputChannels; + config.channelsOut = outputChannels; + config.sampleRateIn = inputSampleRate; + config.sampleRateOut = outputSampleRate; + ma_channel_map_init_standard(ma_standard_channel_map_flac, config.channelMapIn, sizeof(config.channelMapIn)/sizeof(config.channelMapIn[0]), config.channelCountIn); + config.resampling.linear.lpfOrder = MA_MAX_FILTER_ORDER; + ``` + +Do the following to uninitialize the data converter: + + ```c + ma_data_converter_uninit(&converter, NULL); + ``` + +The following example shows how data can be processed + + ```c + ma_uint64 frameCountIn = 1000; + ma_uint64 frameCountOut = 2000; + ma_result result = ma_data_converter_process_pcm_frames(&converter, pFramesIn, &frameCountIn, pFramesOut, &frameCountOut); + if (result != MA_SUCCESS) { + // An error occurred... + } + + // At this point, frameCountIn contains the number of input frames that were consumed and frameCountOut contains the number + // of output frames written. + ``` + +The data converter supports multiple channels and is always interleaved (both input and output). +The channel count cannot be changed after initialization. + +Sample rates can be anything other than zero, and are always specified in hertz. They should be set +to something like 44100, etc. The sample rate is the only configuration property that can be +changed after initialization, but only if the `resampling.allowDynamicSampleRate` member of +`ma_data_converter_config` is set to `MA_TRUE`. To change the sample rate, use +`ma_data_converter_set_rate()` or `ma_data_converter_set_rate_ratio()`. The ratio must be in/out. +The resampling algorithm cannot be changed after initialization. + +Processing always happens on a per PCM frame basis and always assumes interleaved input and output. +De-interleaved processing is not supported. To process frames, use +`ma_data_converter_process_pcm_frames()`. On input, this function takes the number of output frames +you can fit in the output buffer and the number of input frames contained in the input buffer. On +output these variables contain the number of output frames that were written to the output buffer +and the number of input frames that were consumed in the process. You can pass in NULL for the +input buffer in which case it will be treated as an infinitely large +buffer of zeros. The output buffer can also be NULL, in which case the processing will be treated +as seek. + +Sometimes it's useful to know exactly how many input frames will be required to output a specific +number of frames. You can calculate this with `ma_data_converter_get_required_input_frame_count()`. +Likewise, it's sometimes useful to know exactly how many frames would be output given a certain +number of input frames. You can do this with `ma_data_converter_get_expected_output_frame_count()`. + +Due to the nature of how resampling works, the data converter introduces some latency if resampling +is required. This can be retrieved in terms of both the input rate and the output rate with +`ma_data_converter_get_input_latency()` and `ma_data_converter_get_output_latency()`. + + + +11. Filtering +============= + +11.1. Biquad Filtering +---------------------- +Biquad filtering is achieved with the `ma_biquad` API. Example: + + ```c + ma_biquad_config config = ma_biquad_config_init(ma_format_f32, channels, b0, b1, b2, a0, a1, a2); + ma_result result = ma_biquad_init(&config, &biquad); + if (result != MA_SUCCESS) { + // Error. + } + + ... + + ma_biquad_process_pcm_frames(&biquad, pFramesOut, pFramesIn, frameCount); + ``` + +Biquad filtering is implemented using transposed direct form 2. The numerator coefficients are b0, +b1 and b2, and the denominator coefficients are a0, a1 and a2. The a0 coefficient is required and +coefficients must not be pre-normalized. + +Supported formats are `ma_format_s16` and `ma_format_f32`. If you need to use a different format +you need to convert it yourself beforehand. When using `ma_format_s16` the biquad filter will use +fixed point arithmetic. When using `ma_format_f32`, floating point arithmetic will be used. + +Input and output frames are always interleaved. + +Filtering can be applied in-place by passing in the same pointer for both the input and output +buffers, like so: + + ```c + ma_biquad_process_pcm_frames(&biquad, pMyData, pMyData, frameCount); + ``` + +If you need to change the values of the coefficients, but maintain the values in the registers you +can do so with `ma_biquad_reinit()`. This is useful if you need to change the properties of the +filter while keeping the values of registers valid to avoid glitching. Do not use +`ma_biquad_init()` for this as it will do a full initialization which involves clearing the +registers to 0. Note that changing the format or channel count after initialization is invalid and +will result in an error. + + +11.2. Low-Pass Filtering +------------------------ +Low-pass filtering is achieved with the following APIs: + + +---------+------------------------------------------+ + | API | Description | + +---------+------------------------------------------+ + | ma_lpf1 | First order low-pass filter | + | ma_lpf2 | Second order low-pass filter | + | ma_lpf | High order low-pass filter (Butterworth) | + +---------+------------------------------------------+ + +Low-pass filter example: + + ```c + ma_lpf_config config = ma_lpf_config_init(ma_format_f32, channels, sampleRate, cutoffFrequency, order); + ma_result result = ma_lpf_init(&config, &lpf); + if (result != MA_SUCCESS) { + // Error. + } + + ... + + ma_lpf_process_pcm_frames(&lpf, pFramesOut, pFramesIn, frameCount); + ``` + +Supported formats are `ma_format_s16` and` ma_format_f32`. If you need to use a different format +you need to convert it yourself beforehand. Input and output frames are always interleaved. + +Filtering can be applied in-place by passing in the same pointer for both the input and output +buffers, like so: + + ```c + ma_lpf_process_pcm_frames(&lpf, pMyData, pMyData, frameCount); + ``` + +The maximum filter order is limited to `MA_MAX_FILTER_ORDER` which is set to 8. If you need more, +you can chain first and second order filters together. + + ```c + for (iFilter = 0; iFilter < filterCount; iFilter += 1) { + ma_lpf2_process_pcm_frames(&lpf2[iFilter], pMyData, pMyData, frameCount); + } + ``` + +If you need to change the configuration of the filter, but need to maintain the state of internal +registers you can do so with `ma_lpf_reinit()`. This may be useful if you need to change the sample +rate and/or cutoff frequency dynamically while maintaining smooth transitions. Note that changing the +format or channel count after initialization is invalid and will result in an error. + +The `ma_lpf` object supports a configurable order, but if you only need a first order filter you +may want to consider using `ma_lpf1`. Likewise, if you only need a second order filter you can use +`ma_lpf2`. The advantage of this is that they're lighter weight and a bit more efficient. + +If an even filter order is specified, a series of second order filters will be processed in a +chain. If an odd filter order is specified, a first order filter will be applied, followed by a +series of second order filters in a chain. + + +11.3. High-Pass Filtering +------------------------- +High-pass filtering is achieved with the following APIs: + + +---------+-------------------------------------------+ + | API | Description | + +---------+-------------------------------------------+ + | ma_hpf1 | First order high-pass filter | + | ma_hpf2 | Second order high-pass filter | + | ma_hpf | High order high-pass filter (Butterworth) | + +---------+-------------------------------------------+ + +High-pass filters work exactly the same as low-pass filters, only the APIs are called `ma_hpf1`, +`ma_hpf2` and `ma_hpf`. See example code for low-pass filters for example usage. + + +11.4. Band-Pass Filtering +------------------------- +Band-pass filtering is achieved with the following APIs: + + +---------+-------------------------------+ + | API | Description | + +---------+-------------------------------+ + | ma_bpf2 | Second order band-pass filter | + | ma_bpf | High order band-pass filter | + +---------+-------------------------------+ + +Band-pass filters work exactly the same as low-pass filters, only the APIs are called `ma_bpf2` and +`ma_hpf`. See example code for low-pass filters for example usage. Note that the order for +band-pass filters must be an even number which means there is no first order band-pass filter, +unlike low-pass and high-pass filters. + + +11.5. Notch Filtering +--------------------- +Notch filtering is achieved with the following APIs: + + +-----------+------------------------------------------+ + | API | Description | + +-----------+------------------------------------------+ + | ma_notch2 | Second order notching filter | + +-----------+------------------------------------------+ + + +11.6. Peaking EQ Filtering +------------------------- +Peaking filtering is achieved with the following APIs: + + +----------+------------------------------------------+ + | API | Description | + +----------+------------------------------------------+ + | ma_peak2 | Second order peaking filter | + +----------+------------------------------------------+ + + +11.7. Low Shelf Filtering +------------------------- +Low shelf filtering is achieved with the following APIs: + + +-------------+------------------------------------------+ + | API | Description | + +-------------+------------------------------------------+ + | ma_loshelf2 | Second order low shelf filter | + +-------------+------------------------------------------+ + +Where a high-pass filter is used to eliminate lower frequencies, a low shelf filter can be used to +just turn them down rather than eliminate them entirely. + + +11.8. High Shelf Filtering +-------------------------- +High shelf filtering is achieved with the following APIs: + + +-------------+------------------------------------------+ + | API | Description | + +-------------+------------------------------------------+ + | ma_hishelf2 | Second order high shelf filter | + +-------------+------------------------------------------+ + +The high shelf filter has the same API as the low shelf filter, only you would use `ma_hishelf` +instead of `ma_loshelf`. Where a low shelf filter is used to adjust the volume of low frequencies, +the high shelf filter does the same thing for high frequencies. + + + + +12. Waveform and Noise Generation +================================= + +12.1. Waveforms +--------------- +miniaudio supports generation of sine, square, triangle and sawtooth waveforms. This is achieved +with the `ma_waveform` API. Example: + + ```c + ma_waveform_config config = ma_waveform_config_init( + FORMAT, + CHANNELS, + SAMPLE_RATE, + ma_waveform_type_sine, + amplitude, + frequency); + + ma_waveform waveform; + ma_result result = ma_waveform_init(&config, &waveform); + if (result != MA_SUCCESS) { + // Error. + } + + ... + + ma_waveform_read_pcm_frames(&waveform, pOutput, frameCount); + ``` + +The amplitude, frequency, type, and sample rate can be changed dynamically with +`ma_waveform_set_amplitude()`, `ma_waveform_set_frequency()`, `ma_waveform_set_type()`, and +`ma_waveform_set_sample_rate()` respectively. + +You can invert the waveform by setting the amplitude to a negative value. You can use this to +control whether or not a sawtooth has a positive or negative ramp, for example. + +Below are the supported waveform types: + + +---------------------------+ + | Enum Name | + +---------------------------+ + | ma_waveform_type_sine | + | ma_waveform_type_square | + | ma_waveform_type_triangle | + | ma_waveform_type_sawtooth | + +---------------------------+ + + + +12.2. Noise +----------- +miniaudio supports generation of white, pink and Brownian noise via the `ma_noise` API. Example: + + ```c + ma_noise_config config = ma_noise_config_init( + FORMAT, + CHANNELS, + ma_noise_type_white, + SEED, + amplitude); + + ma_noise noise; + ma_result result = ma_noise_init(&config, &noise); + if (result != MA_SUCCESS) { + // Error. + } + + ... + + ma_noise_read_pcm_frames(&noise, pOutput, frameCount); + ``` + +The noise API uses simple LCG random number generation. It supports a custom seed which is useful +for things like automated testing requiring reproducibility. Setting the seed to zero will default +to `MA_DEFAULT_LCG_SEED`. + +The amplitude and seed can be changed dynamically with `ma_noise_set_amplitude()` and +`ma_noise_set_seed()` respectively. + +By default, the noise API will use different values for different channels. So, for example, the +left side in a stereo stream will be different to the right side. To instead have each channel use +the same random value, set the `duplicateChannels` member of the noise config to true, like so: + + ```c + config.duplicateChannels = MA_TRUE; + ``` + +Below are the supported noise types. + + +------------------------+ + | Enum Name | + +------------------------+ + | ma_noise_type_white | + | ma_noise_type_pink | + | ma_noise_type_brownian | + +------------------------+ + + + +13. Audio Buffers +================= +miniaudio supports reading from a buffer of raw audio data via the `ma_audio_buffer` API. This can +read from memory that's managed by the application, but can also handle the memory management for +you internally. Memory management is flexible and should support most use cases. + +Audio buffers are initialized using the standard configuration system used everywhere in miniaudio: + + ```c + ma_audio_buffer_config config = ma_audio_buffer_config_init( + format, + channels, + sizeInFrames, + pExistingData, + &allocationCallbacks); + + ma_audio_buffer buffer; + result = ma_audio_buffer_init(&config, &buffer); + if (result != MA_SUCCESS) { + // Error. + } + + ... + + ma_audio_buffer_uninit(&buffer); + ``` + +In the example above, the memory pointed to by `pExistingData` will *not* be copied and is how an +application can do self-managed memory allocation. If you would rather make a copy of the data, use +`ma_audio_buffer_init_copy()`. To uninitialize the buffer, use `ma_audio_buffer_uninit()`. + +Sometimes it can be convenient to allocate the memory for the `ma_audio_buffer` structure and the +raw audio data in a contiguous block of memory. That is, the raw audio data will be located +immediately after the `ma_audio_buffer` structure. To do this, use +`ma_audio_buffer_alloc_and_init()`: + + ```c + ma_audio_buffer_config config = ma_audio_buffer_config_init( + format, + channels, + sizeInFrames, + pExistingData, + &allocationCallbacks); + + ma_audio_buffer* pBuffer + result = ma_audio_buffer_alloc_and_init(&config, &pBuffer); + if (result != MA_SUCCESS) { + // Error + } + + ... + + ma_audio_buffer_uninit_and_free(&buffer); + ``` + +If you initialize the buffer with `ma_audio_buffer_alloc_and_init()` you should uninitialize it +with `ma_audio_buffer_uninit_and_free()`. In the example above, the memory pointed to by +`pExistingData` will be copied into the buffer, which is contrary to the behavior of +`ma_audio_buffer_init()`. + +An audio buffer has a playback cursor just like a decoder. As you read frames from the buffer, the +cursor moves forward. The last parameter (`loop`) can be used to determine if the buffer should +loop. The return value is the number of frames actually read. If this is less than the number of +frames requested it means the end has been reached. This should never happen if the `loop` +parameter is set to true. If you want to manually loop back to the start, you can do so with with +`ma_audio_buffer_seek_to_pcm_frame(pAudioBuffer, 0)`. Below is an example for reading data from an +audio buffer. + + ```c + ma_uint64 framesRead = ma_audio_buffer_read_pcm_frames(pAudioBuffer, pFramesOut, desiredFrameCount, isLooping); + if (framesRead < desiredFrameCount) { + // If not looping, this means the end has been reached. This should never happen in looping mode with valid input. + } + ``` + +Sometimes you may want to avoid the cost of data movement between the internal buffer and the +output buffer. Instead you can use memory mapping to retrieve a pointer to a segment of data: + + ```c + void* pMappedFrames; + ma_uint64 frameCount = frameCountToTryMapping; + ma_result result = ma_audio_buffer_map(pAudioBuffer, &pMappedFrames, &frameCount); + if (result == MA_SUCCESS) { + // Map was successful. The value in frameCount will be how many frames were _actually_ mapped, which may be + // less due to the end of the buffer being reached. + ma_copy_pcm_frames(pFramesOut, pMappedFrames, frameCount, pAudioBuffer->format, pAudioBuffer->channels); + + // You must unmap the buffer. + ma_audio_buffer_unmap(pAudioBuffer, frameCount); + } + ``` + +When you use memory mapping, the read cursor is increment by the frame count passed in to +`ma_audio_buffer_unmap()`. If you decide not to process every frame you can pass in a value smaller +than the value returned by `ma_audio_buffer_map()`. The disadvantage to using memory mapping is +that it does not handle looping for you. You can determine if the buffer is at the end for the +purpose of looping with `ma_audio_buffer_at_end()` or by inspecting the return value of +`ma_audio_buffer_unmap()` and checking if it equals `MA_AT_END`. You should not treat `MA_AT_END` +as an error when returned by `ma_audio_buffer_unmap()`. + + + +14. Ring Buffers +================ +miniaudio supports lock free (single producer, single consumer) ring buffers which are exposed via +the `ma_rb` and `ma_pcm_rb` APIs. The `ma_rb` API operates on bytes, whereas the `ma_pcm_rb` +operates on PCM frames. They are otherwise identical as `ma_pcm_rb` is just a wrapper around +`ma_rb`. + +Unlike most other APIs in miniaudio, ring buffers support both interleaved and deinterleaved +streams. The caller can also allocate their own backing memory for the ring buffer to use +internally for added flexibility. Otherwise the ring buffer will manage it's internal memory for +you. + +The examples below use the PCM frame variant of the ring buffer since that's most likely the one +you will want to use. To initialize a ring buffer, do something like the following: + + ```c + ma_pcm_rb rb; + ma_result result = ma_pcm_rb_init(FORMAT, CHANNELS, BUFFER_SIZE_IN_FRAMES, NULL, NULL, &rb); + if (result != MA_SUCCESS) { + // Error + } + ``` + +The `ma_pcm_rb_init()` function takes the sample format and channel count as parameters because +it's the PCM variant of the ring buffer API. For the regular ring buffer that operates on bytes you +would call `ma_rb_init()` which leaves these out and just takes the size of the buffer in bytes +instead of frames. The fourth parameter is an optional pre-allocated buffer and the fifth parameter +is a pointer to a `ma_allocation_callbacks` structure for custom memory allocation routines. +Passing in `NULL` for this results in `MA_MALLOC()` and `MA_FREE()` being used. + +Use `ma_pcm_rb_init_ex()` if you need a deinterleaved buffer. The data for each sub-buffer is +offset from each other based on the stride. To manage your sub-buffers you can use +`ma_pcm_rb_get_subbuffer_stride()`, `ma_pcm_rb_get_subbuffer_offset()` and +`ma_pcm_rb_get_subbuffer_ptr()`. + +Use `ma_pcm_rb_acquire_read()` and `ma_pcm_rb_acquire_write()` to retrieve a pointer to a section +of the ring buffer. You specify the number of frames you need, and on output it will set to what +was actually acquired. If the read or write pointer is positioned such that the number of frames +requested will require a loop, it will be clamped to the end of the buffer. Therefore, the number +of frames you're given may be less than the number you requested. + +After calling `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()`, you do your work on the +buffer and then "commit" it with `ma_pcm_rb_commit_read()` or `ma_pcm_rb_commit_write()`. This is +where the read/write pointers are updated. When you commit you need to pass in the buffer that was +returned by the earlier call to `ma_pcm_rb_acquire_read()` or `ma_pcm_rb_acquire_write()` and is +only used for validation. The number of frames passed to `ma_pcm_rb_commit_read()` and +`ma_pcm_rb_commit_write()` is what's used to increment the pointers, and can be less that what was +originally requested. + +If you want to correct for drift between the write pointer and the read pointer you can use a +combination of `ma_pcm_rb_pointer_distance()`, `ma_pcm_rb_seek_read()` and +`ma_pcm_rb_seek_write()`. Note that you can only move the pointers forward, and you should only +move the read pointer forward via the consumer thread, and the write pointer forward by the +producer thread. If there is too much space between the pointers, move the read pointer forward. If +there is too little space between the pointers, move the write pointer forward. + +You can use a ring buffer at the byte level instead of the PCM frame level by using the `ma_rb` +API. This is exactly the same, only you will use the `ma_rb` functions instead of `ma_pcm_rb` and +instead of frame counts you will pass around byte counts. + +The maximum size of the buffer in bytes is `0x7FFFFFFF-(MA_SIMD_ALIGNMENT-1)` due to the most +significant bit being used to encode a loop flag and the internally managed buffers always being +aligned to `MA_SIMD_ALIGNMENT`. + +Note that the ring buffer is only thread safe when used by a single consumer thread and single +producer thread. + + + +15. Backends +============ +The following backends are supported by miniaudio. These are listed in order of default priority. +When no backend is specified when initializing a context or device, miniaudio will attempt to use +each of these backends in the order listed in the table below. + +Note that backends that are not usable by the build target will not be included in the build. For +example, ALSA, which is specific to Linux, will not be included in the Windows build. + + +-------------+-----------------------+--------------------------------------------------------+ + | Name | Enum Name | Supported Operating Systems | + +-------------+-----------------------+--------------------------------------------------------+ + | WASAPI | ma_backend_wasapi | Windows Vista+ | + | DirectSound | ma_backend_dsound | Windows XP+ | + | WinMM | ma_backend_winmm | Windows 95+ | + | Core Audio | ma_backend_coreaudio | macOS, iOS | + | sndio | ma_backend_sndio | OpenBSD | + | audio(4) | ma_backend_audio4 | NetBSD, OpenBSD | + | OSS | ma_backend_oss | FreeBSD | + | PulseAudio | ma_backend_pulseaudio | Cross Platform (disabled on Windows, BSD and Android) | + | ALSA | ma_backend_alsa | Linux | + | JACK | ma_backend_jack | Cross Platform (disabled on BSD and Android) | + | AAudio | ma_backend_aaudio | Android 8+ | + | OpenSL ES | ma_backend_opensl | Android (API level 16+) | + | Web Audio | ma_backend_webaudio | Web (via Emscripten) | + | Custom | ma_backend_custom | Cross Platform | + | Null | ma_backend_null | Cross Platform (not used on Web) | + +-------------+-----------------------+--------------------------------------------------------+ + +Some backends have some nuance details you may want to be aware of. + +15.1. WASAPI +------------ +- Low-latency shared mode will be disabled when using an application-defined sample rate which is + different to the device's native sample rate. To work around this, set `wasapi.noAutoConvertSRC` + to true in the device config. This is due to IAudioClient3_InitializeSharedAudioStream() failing + when the `AUDCLNT_STREAMFLAGS_AUTOCONVERTPCM` flag is specified. Setting wasapi.noAutoConvertSRC + will result in miniaudio's internal resampler being used instead which will in turn enable the + use of low-latency shared mode. + +15.2. PulseAudio +---------------- +- If you experience bad glitching/noise on Arch Linux, consider this fix from the Arch wiki: + https://wiki.archlinux.org/index.php/PulseAudio/Troubleshooting#Glitches,_skips_or_crackling. + Alternatively, consider using a different backend such as ALSA. + +15.3. Android +------------- +- To capture audio on Android, remember to add the RECORD_AUDIO permission to your manifest: + `` +- With OpenSL|ES, only a single ma_context can be active at any given time. This is due to a + limitation with OpenSL|ES. +- With AAudio, only default devices are enumerated. This is due to AAudio not having an enumeration + API (devices are enumerated through Java). You can however perform your own device enumeration + through Java and then set the ID in the ma_device_id structure (ma_device_id.aaudio) and pass it + to ma_device_init(). +- The backend API will perform resampling where possible. The reason for this as opposed to using + miniaudio's built-in resampler is to take advantage of any potential device-specific + optimizations the driver may implement. + +BSD +--- +- The sndio backend is currently only enabled on OpenBSD builds. +- The audio(4) backend is supported on OpenBSD, but you may need to disable sndiod before you can + use it. + +15.4. UWP +--------- +- UWP only supports default playback and capture devices. +- UWP requires the Microphone capability to be enabled in the application's manifest (Package.appxmanifest): + + ``` + + ... + + + + + ``` + +15.5. Web Audio / Emscripten +---------------------------- +- You cannot use `-std=c*` compiler flags, nor `-ansi`. This only applies to the Emscripten build. +- The first time a context is initialized it will create a global object called "miniaudio" whose + primary purpose is to act as a factory for device objects. +- Currently the Web Audio backend uses ScriptProcessorNode's, but this may need to change later as + they've been deprecated. +- Google has implemented a policy in their browsers that prevent automatic media output without + first receiving some kind of user input. The following web page has additional details: + https://developers.google.com/web/updates/2017/09/autoplay-policy-changes. Starting the device + may fail if you try to start playback without first handling some kind of user input. + + + +16. Optimization Tips +===================== +See below for some tips on improving performance. + +16.1. Low Level API +------------------- +- In the data callback, if your data is already clipped prior to copying it into the output buffer, + set the `noClip` config option in the device config to true. This will disable miniaudio's built + in clipping function. +- By default, miniaudio will pre-silence the data callback's output buffer. If you know that you + will always write valid data to the output buffer you can disable pre-silencing by setting the + `noPreSilence` config option in the device config to true. + +16.2. High Level API +-------------------- +- If a sound does not require doppler or pitch shifting, consider disabling pitching by + initializing the sound with the `MA_SOUND_FLAG_NO_PITCH` flag. +- If a sound does not require spatialization, disable it by initializing the sound with the + `MA_SOUND_FLAG_NO_SPATIALIZATION` flag. It can be re-enabled again post-initialization with + `ma_sound_set_spatialization_enabled()`. +- If you know all of your sounds will always be the same sample rate, set the engine's sample + rate to match that of the sounds. Likewise, if you're using a self-managed resource manager, + consider setting the decoded sample rate to match your sounds. By configuring everything to + use a consistent sample rate, sample rate conversion can be avoided. + + + +17. Miscellaneous Notes +======================= +- Automatic stream routing is enabled on a per-backend basis. Support is explicitly enabled for + WASAPI and Core Audio, however other backends such as PulseAudio may naturally support it, though + not all have been tested. +- When compiling with VC6 and earlier, decoding is restricted to files less than 2GB in size. This + is due to 64-bit file APIs not being available. +*/ + +#ifndef miniaudio_h +#define miniaudio_h + +#ifdef __cplusplus +extern "C" { +#endif + +#define MA_STRINGIFY(x) #x +#define MA_XSTRINGIFY(x) MA_STRINGIFY(x) + +#define MA_VERSION_MAJOR 0 +#define MA_VERSION_MINOR 11 +#define MA_VERSION_REVISION 21 +#define MA_VERSION_STRING MA_XSTRINGIFY(MA_VERSION_MAJOR) "."

These callbacks are grouped into two parts: context and device. There is one context +to many devices. A device is created from a context. + +The general flow goes like this: + + 1) A context is created with `onContextInit()` + 1a) Available devices can be enumerated with `onContextEnumerateDevices()` if required. + 1b) Detailed information about a device can be queried with `onContextGetDeviceInfo()` if required. + 2) A device is created from the context that was created in the first step using `onDeviceInit()`, and optionally a device ID that was + selected from device enumeration via `onContextEnumerateDevices()`. + 3) A device is started or stopped with `onDeviceStart()` / `onDeviceStop()` + 4) Data is delivered to and from the device by the backend. This is always done based on the native format returned by the prior call + to `onDeviceInit()`. Conversion between the device's native format and the format requested by the application will be handled by + miniaudio internally. + +Initialization of the context is quite simple. You need to do any necessary initialization of internal objects and then output the +callbacks defined in this structure. + +Once the context has been initialized you can initialize a device. Before doing so, however, the application may want to know which +physical devices are available. This is where `onContextEnumerateDevices()` comes in. This is fairly simple. For each device, fire the +given callback with, at a minimum, the basic information filled out in `ma_device_info`. When the callback returns `MA_FALSE`, enumeration +needs to stop and the `onContextEnumerateDevices()` function returns with a success code. + +Detailed device information can be retrieved from a device ID using `onContextGetDeviceInfo()`. This takes as input the device type and ID, +and on output returns detailed information about the device in `ma_device_info`. The `onContextGetDeviceInfo()` callback must handle the +case when the device ID is NULL, in which case information about the default device needs to be retrieved. + +Once the context has been created and the device ID retrieved (if using anything other than the default device), the device can be created. +This is a little bit more complicated than initialization of the context due to it's more complicated configuration. When initializing a +device, a duplex device may be requested. This means a separate data format needs to be specified for both playback and capture. On input, +the data format is set to what the application wants. On output it's set to the native format which should match as closely as possible to +the requested format. The conversion between the format requested by the application and the device's native format will be handled +internally by miniaudio. + +On input, if the sample format is set to `ma_format_unknown`, the backend is free to use whatever sample format it desires, so long as it's +supported by miniaudio. When the channel count is set to 0, the backend should use the device's native channel count. The same applies for +sample rate. For the channel map, the default should be used when `ma_channel_map_is_blank()` returns true (all channels set to +`MA_CHANNEL_NONE`). On input, the `periodSizeInFrames` or `periodSizeInMilliseconds` option should always be set. The backend should +inspect both of these variables. If `periodSizeInFrames` is set, it should take priority, otherwise it needs to be derived from the period +size in milliseconds (`periodSizeInMilliseconds`) and the sample rate, keeping in mind that the sample rate may be 0, in which case the +sample rate will need to be determined before calculating the period size in frames. On output, all members of the `ma_device_descriptor` +object should be set to a valid value, except for `periodSizeInMilliseconds` which is optional (`periodSizeInFrames` *must* be set). + +Starting and stopping of the device is done with `onDeviceStart()` and `onDeviceStop()` and should be self-explanatory. If the backend uses +asynchronous reading and writing, `onDeviceStart()` and `onDeviceStop()` should always be implemented. + +The handling of data delivery between the application and the device is the most complicated part of the process. To make this a bit +easier, some helper callbacks are available. If the backend uses a blocking read/write style of API, the `onDeviceRead()` and +`onDeviceWrite()` callbacks can optionally be implemented. These are blocking and work just like reading and writing from a file. If the +backend uses a callback for data delivery, that callback must call `ma_device_handle_backend_data_callback()` from within it's callback. +This allows miniaudio to then process any necessary data conversion and then pass it to the miniaudio data callback. + +If the backend requires absolute flexibility with it's data delivery, it can optionally implement the `onDeviceDataLoop()` callback +which will allow it to implement the logic that will run on the audio thread. This is much more advanced and is completely optional. + +The audio thread should run data delivery logic in a loop while `ma_device_get_state() == ma_device_state_started` and no errors have been +encountered. Do not start or stop the device here. That will be handled from outside the `onDeviceDataLoop()` callback. + +The invocation of the `onDeviceDataLoop()` callback will be handled by miniaudio. When you start the device, miniaudio will fire this +callback. When the device is stopped, the `ma_device_get_state() == ma_device_state_started` condition will fail and the loop will be terminated +which will then fall through to the part that stops the device. For an example on how to implement the `onDeviceDataLoop()` callback, +look at `ma_device_audio_thread__default_read_write()`. Implement the `onDeviceDataLoopWakeup()` callback if you need a mechanism to +wake up the audio thread. + +If the backend supports an optimized retrieval of device information from an initialized `ma_device` object, it should implement the +`onDeviceGetInfo()` callback. This is optional, in which case it will fall back to `onContextGetDeviceInfo()` which is less efficient. +*/ +struct ma_backend_callbacks +{ + ma_result (* onContextInit)(ma_context* pContext, const ma_context_config* pConfig, ma_backend_callbacks* pCallbacks); + ma_result (* onContextUninit)(ma_context* pContext); + ma_result (* onContextEnumerateDevices)(ma_context* pContext, ma_enum_devices_callback_proc callback, void* pUserData); + ma_result (* onContextGetDeviceInfo)(ma_context* pContext, ma_device_type deviceType, const ma_device_id* pDeviceID, ma_device_info* pDeviceInfo); + ma_result (* onDeviceInit)(ma_device* pDevice, const ma_device_config* pConfig, ma_device_descriptor* pDescriptorPlayback, ma_device_descriptor* pDescriptorCapture); + ma_result (* onDeviceUninit)(ma_device* pDevice); + ma_result (* onDeviceStart)(ma_device* pDevice); + ma_result (* onDeviceStop)(ma_device* pDevice); + ma_result (* onDeviceRead)(ma_device* pDevice, void* pFrames, ma_uint32 frameCount, ma_uint32* pFramesRead); + ma_result (* onDeviceWrite)(ma_device* pDevice, const void* pFrames, ma_uint32 frameCount, ma_uint32* pFramesWritten); + ma_result (* onDeviceDataLoop)(ma_device* pDevice); + ma_result (* onDeviceDataLoopWakeup)(ma_device* pDevice); + ma_result (* onDeviceGetInfo)(ma_device* pDevice, ma_device_type type, ma_device_info* pDeviceInfo); +}; + +struct ma_context_config +{ + ma_log* pLog; + ma_thread_priority threadPriority; + size_t threadStackSize; + void* pUserData; + ma_allocation_callbacks allocationCallbacks; + struct + { + ma_bool32 useVerboseDeviceEnumeration; + } alsa; + struct + { + const char* pApplicationName; + const char* pServerName; + ma_bool32 tryAutoSpawn; /* Enables autospawning of the PulseAudio daemon if necessary. */ + } pulse; + struct + { + ma_ios_session_category sessionCategory; + ma_uint32 sessionCategoryOptions; + ma_bool32 noAudioSessionActivate; /* iOS only.

The idea is you send or receive audio data from the device to either play it back through a speaker, or capture it +from a microphone. Whether or not you should send or receive data from the device (or both) depends on the type of device you are initializing which can be +playback, capture, full-duplex or loopback. (Note that loopback mode is only supported on select backends.) Sending and receiving audio data to and from the +device is done via a callback which is fired by miniaudio at periodic time intervals. + +The frequency at which data is delivered to and from a device depends on the size of it's period. The size of the period can be defined in terms of PCM frames +or milliseconds, whichever is more convenient.

If both are 0 the default buffer size will be + used depending on the selected performance profile. The value affects latency. See below for details. + + periods + The number of periods making up the device's entire buffer. The total buffer size is `periodSizeInFrames` or `periodSizeInMilliseconds` multiplied by + this value. This is just a hint as backends will be the ones who ultimately decide how your periods will be configured. + + performanceProfile + A hint to miniaudio as to the performance requirements of your program. Can be either `ma_performance_profile_low_latency` (default) or + `ma_performance_profile_conservative`. This mainly affects the size of default buffers and can usually be left at it's default value. + + noPreSilencedOutputBuffer + When set to true, the contents of the output buffer passed into the data callback will be left undefined.

You can access this directly from the device object like `device.pUserData`. + + resampling.algorithm + The resampling algorithm to use when miniaudio needs to perform resampling between the rate specified by `sampleRate` and the device's native rate. The + default value is `ma_resample_algorithm_linear`, and the quality can be configured with `resampling.linear.lpfOrder`. + + resampling.pBackendVTable + A pointer to an optional vtable that can be used for plugging in a custom resampler. + + resampling.pBackendUserData + A pointer that will passed to callbacks in pBackendVTable. + + resampling.linear.lpfOrder + The linear resampler applies a low-pass filter as part of it's processing for anti-aliasing. This setting controls the order of the filter. The higher + the value, the better the quality, in general. Setting this to 0 will disable low-pass filtering altogether. The maximum value is + `MA_MAX_FILTER_ORDER`. The default value is `min(4, MA_MAX_FILTER_ORDER)`. + + playback.pDeviceID + A pointer to a `ma_device_id` structure containing the ID of the playback device to initialize.

Note that if you specify + exclusive mode, but it's not supported by the backend, initialization will fail. You can then fall back to shared mode if desired by changing this to + ma_share_mode_shared and reinitializing. + + wasapi.noAutoConvertSRC + WASAPI only. When set to true, disables WASAPI's automatic resampling and forces the use of miniaudio's resampler. Defaults to false. + + wasapi.noDefaultQualitySRC + WASAPI only.

Sets the stream name for capture. + + coreaudio.allowNominalSampleRateChange + Core Audio only. Desktop only. When enabled, allows the sample rate of the device to be changed at the operating system level. This + is disabled by default in order to prevent intrusive changes to the user's system. This is useful if you want to use a sample rate + that is known to be natively supported by the hardware thereby avoiding the cost of resampling. When set to true, miniaudio will + find the closest match between the sample rate requested in the device config and the sample rates natively supported by the + hardware. When set to false, the sample rate currently set by the operating system will always be used. + + opensl.streamType + OpenSL only. Explicitly sets the stream type. If left unset (`ma_opensl_stream_type_default`), the + stream type will be left unset. Think of this as the type of audio you're playing. + + opensl.recordingPreset + OpenSL only. Explicitly sets the type of recording your program will be doing. When left + unset, the recording preset will be left unchanged. + + aaudio.usage + AAudio only. Explicitly sets the nature of the audio the program will be consuming. When + left unset, the usage will be left unchanged. + + aaudio.contentType + AAudio only. Sets the content type. When left unset, the content type will be left unchanged. + + aaudio.inputPreset + AAudio only. Explicitly sets the type of recording your program will be doing. When left + unset, the input preset will be left unchanged. + + aaudio.noAutoStartAfterReroute + AAudio only. Controls whether or not the device should be automatically restarted after a + stream reroute. When set to false (default) the device will be restarted automatically; + otherwise the device will be stopped. + + +Once initialized, the device's config is immutable. If you need to change the config you will need to initialize a new device. + +After initializing the device it will be in a stopped state. To start it, use `ma_device_start()`. + +If both `periodSizeInFrames` and `periodSizeInMilliseconds` are set to zero, it will default to `MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_LOW_LATENCY` or +`MA_DEFAULT_PERIOD_SIZE_IN_MILLISECONDS_CONSERVATIVE`, depending on whether or not `performanceProfile` is set to `ma_performance_profile_low_latency` or +`ma_performance_profile_conservative`. + +If you request exclusive mode and the backend does not support it an error will be returned. For robustness, you may want to first try initializing the device +in exclusive mode, and then fall back to shared mode if required. Alternatively you can just request shared mode (the default if you leave it unset in the +config) which is the most reliable option. Some backends do not have a practical way of choosing whether or not the device should be exclusive or not (ALSA, +for example) in which case it just acts as a hint. Unless you have special requirements you should try avoiding exclusive mode as it's intrusive to the user. +Starting with Windows 10, miniaudio will use low-latency shared mode where possible which may make exclusive mode unnecessary. + +When sending or receiving data to/from a device, miniaudio will internally perform a format conversion to convert between the format specified by the config +and the format used internally by the backend. If you pass in 0 for the sample format, channel count, sample rate _and_ channel map, data transmission will run +on an optimized pass-through fast path. You can retrieve the format, channel count and sample rate by inspecting the `playback/capture.format`, +`playback/capture.channels` and `sampleRate` members of the device object. + +When compiling for UWP you must ensure you call this function on the main UI thread because the operating system may need to present the user with a message +asking for permissions. Please refer to the official documentation for ActivateAudioInterfaceAsync() for more information. + +ALSA Specific: When initializing the default device, requesting shared mode will try using the "dmix" device for playback and the "dsnoop" device for capture. +If these fail it will try falling back to the "hw" device. + + +Example 1 - Simple Initialization +--------------------------------- +This example shows how to initialize a simple playback device using a standard configuration.

This is a brief description of what's going on +in the PulseAudio backend. I apologize if this gets a bit ranty for your liking - you might want to skip this discussion. + +PulseAudio has something they call the "Simple API", which unfortunately isn't suitable for miniaudio. I've not seen anywhere where it +allows you to enumerate over devices, nor does it seem to support the ability to stop and start streams. Looking at the documentation, it +appears as though the stream is constantly running and you prevent sound from being emitted or captured by simply not calling the read or +write functions. This is not a professional solution as it would be much better to *actually* stop the underlying stream. Perhaps the +simple API has some smarts to do this automatically, but I'm not sure. Another limitation with the simple API is that it seems inefficient +when you want to have multiple streams to a single context. For these reasons, miniaudio is not using the simple API. + +Since we're not using the simple API, we're left with the asynchronous API as our only other option. And boy, is this where it starts to +get fun, and I don't mean that in a good way... + +The problems start with the very name of the API - "asynchronous". Yes, this is an asynchronous oriented API which means your commands +don't immediately take effect. You instead need to issue your commands, and then wait for them to complete. The waiting mechanism is +enabled through the use of a "main loop". In the asychronous API you cannot get away from the main loop, and the main loop is where almost +all of PulseAudio's problems stem from. + +When you first initialize PulseAudio you need an object referred to as "main loop". You can implement this yourself by defining your own +vtable, but it's much easier to just use one of the built-in main loop implementations. There's two generic implementations called +pa_mainloop and pa_threaded_mainloop, and another implementation specific to GLib called pa_glib_mainloop. We're using pa_threaded_mainloop +because it simplifies management of the worker thread. The idea of the main loop object is pretty self explanatory - you're supposed to use +it to implement a worker thread which runs in a loop. The main loop is where operations are actually executed. + +To initialize the main loop, you just use `pa_threaded_mainloop_new()`. This is the first function you'll call. You can then get a pointer +to the vtable with `pa_threaded_mainloop_get_api()` (the main loop vtable is called `pa_mainloop_api`). Again, you can bypass the threaded +main loop object entirely and just implement `pa_mainloop_api` directly, but there's no need for it unless you're doing something extremely +specialized such as if you want to integrate it into your application's existing main loop infrastructure. + +(EDIT 2021-01-26: miniaudio is no longer using `pa_threaded_mainloop` due to this issue: https://github.com/mackron/miniaudio/issues/262. +It is now using `pa_mainloop` which turns out to be a simpler solution anyway. The rest of this rant still applies, however.) + +Once you have your main loop vtable (the `pa_mainloop_api` object) you can create the PulseAudio context. This is very similar to +miniaudio's context and they map to each other quite well. You have one context to many streams, which is basically the same as miniaudio's +one `ma_context` to many `ma_device`s. Here's where it starts to get annoying, however. When you first create the PulseAudio context, which +is done with `pa_context_new()`, it's not actually connected to anything. When you connect, you call `pa_context_connect()`. However, if +you remember, PulseAudio is an asynchronous API. That means you cannot just assume the context is connected after `pa_context_context()` +has returned. You instead need to wait for it to connect. To do this, you need to either wait for a callback to get fired, which you can +set with `pa_context_set_state_callback()`, or you can continuously poll the context's state. Either way, you need to run this in a loop. +All objects from here out are created from the context, and, I believe, you can't be creating these objects until the context is connected. +This waiting loop is therefore unavoidable. In order for the waiting to ever complete, however, the main loop needs to be running. Before +attempting to connect the context, the main loop needs to be started with `pa_threaded_mainloop_start()`. + +The reason for this asynchronous design is to support cases where you're connecting to a remote server, say through a local network or an +internet connection. However, the *VAST* majority of cases don't involve this at all - they just connect to a local "server" running on the +host machine. The fact that this would be the default rather than making `pa_context_connect()` synchronous tends to boggle the mind. + +Once the context has been created and connected you can start creating a stream. A PulseAudio stream is analogous to miniaudio's device. +The initialization of a stream is fairly standard - you configure some attributes (analogous to miniaudio's device config) and then call +`pa_stream_new()` to actually create it. Here is where we start to get into "operations". When configuring the stream, you can get +information about the source (such as sample format, sample rate, etc.), however it's not synchronous. Instead, a `pa_operation` object +is returned from `pa_context_get_source_info_by_name()` (capture) or `pa_context_get_sink_info_by_name()` (playback). Then, you need to +run a loop (again!) to wait for the operation to complete which you can determine via a callback or polling, just like we did with the +context. Then, as an added bonus, you need to decrement the reference counter of the `pa_operation` object to ensure memory is cleaned up. +All of that just to retrieve basic information about a device! + +Once the basic information about the device has been retrieved, miniaudio can now create the stream with `ma_stream_new()`. Like the +context, this needs to be connected. But we need to be careful here, because we're now about to introduce one of the most horrific design +choices in PulseAudio. + +PulseAudio allows you to specify a callback that is fired when data can be written to or read from a stream. The language is important here +because PulseAudio takes it literally, specifically the "can be". You would think these callbacks would be appropriate as the place for +writing and reading data to and from the stream, and that would be right, except when it's not. When you initialize the stream, you can +set a flag that tells PulseAudio to not start the stream automatically. This is required because miniaudio does not auto-start devices +straight after initialization - you need to call `ma_device_start()` manually. The problem is that even when this flag is specified, +PulseAudio will immediately fire it's write or read callback. This is *technically* correct (based on the wording in the documentation) +because indeed, data *can* be written at this point. The problem is that it's not *practical*. It makes sense that the write/read callback +would be where a program will want to write or read data to or from the stream, but when it's called before the application has even +requested that the stream be started, it's just not practical because the program probably isn't ready for any kind of data delivery at +that point (it may still need to load files or whatnot). Instead, this callback should only be fired when the application requests the +stream be started which is how it works with literally *every* other callback-based audio API. Since miniaudio forbids firing of the data +callback until the device has been started (as it should be with *all* callback based APIs), logic needs to be added to ensure miniaudio +doesn't just blindly fire the application-defined data callback from within the PulseAudio callback before the stream has actually been +started. The device state is used for this - if the state is anything other than `ma_device_state_starting` or `ma_device_state_started`, the main data +callback is not fired. + +This, unfortunately, is not the end of the problems with the PulseAudio write callback. Any normal callback based audio API will +continuously fire the callback at regular intervals based on the size of the internal buffer. This will only ever be fired when the device +is running, and will be fired regardless of whether or not the user actually wrote anything to the device/stream. This not the case in +PulseAudio. In PulseAudio, the data callback will *only* be called if you wrote something to it previously. That means, if you don't call +`pa_stream_write()`, the callback will not get fired. On the surface you wouldn't think this would matter because you should be always +writing data, and if you don't have anything to write, just write silence. That's fine until you want to drain the stream. You see, if +you're continuously writing data to the stream, the stream will never get drained! That means in order to drain the stream, you need to +*not* write data to it! But remember, when you don't write data to the stream, the callback won't get fired again! Why is draining +important? Because that's how we've defined stopping to work in miniaudio. In miniaudio, stopping the device requires it to be drained +before returning from ma_device_stop(). So we've stopped the device, which requires us to drain, but draining requires us to *not* write +data to the stream (or else it won't ever complete draining), but not writing to the stream means the callback won't get fired again! + +This becomes a problem when stopping and then restarting the device. When the device is stopped, it's drained, which requires us to *not* +write anything to the stream. But then, since we didn't write anything to it, the write callback will *never* get called again if we just +resume the stream naively. This means that starting the stream requires us to write data to the stream from outside the callback. This +disconnect is something PulseAudio has got seriously wrong - there should only ever be a single source of data delivery, that being the +callback. (I have tried using `pa_stream_flush()` to trigger the write callback to fire, but this just doesn't work for some reason.) + +Once you've created the stream, you need to connect it which involves the whole waiting procedure. This is the same process as the context, +only this time you'll poll for the state with `pa_stream_get_status()`. The starting and stopping of a streaming is referred to as +"corking" in PulseAudio. The analogy is corking a barrel. To start the stream, you uncork it, to stop it you cork it. Personally I think +it's silly - why would you not just call it "starting" and "stopping" like any other normal audio API? Anyway, the act of corking is, you +guessed it, asynchronous. This means you'll need our waiting loop as usual. Again, why this asynchronous design is the default is +absolutely beyond me. Would it really be that hard to just make it run synchronously? + +Teardown is pretty simple (what?!). It's just a matter of calling the relevant `_unref()` function on each object in reverse order that +they were initialized in. + +That's about it from the PulseAudio side. A bit ranty, I know, but they really need to fix that main loop and callback system. They're +embarrassingly unpractical. The main loop thing is an easy fix - have synchronous versions of all APIs. If an application wants these to +run asynchronously, they can execute them in a separate thread themselves. The desire to run these asynchronously is such a niche +requirement - it makes no sense to make it the default. The stream write callback needs to be change, or an alternative provided, that is +constantly fired, regardless of whether or not `pa_stream_write()` has been called, and it needs to take a pointer to a buffer as a +parameter which the program just writes to directly rather than having to call `pa_stream_writable_size()` and `pa_stream_write()`. These +changes alone will change PulseAudio from one of the worst audio APIs to one of the best. +*/ + + +/* +It is assumed pulseaudio.h is available when linking at compile time.

+#endif + +/* +Core Audio + +So far, Core Audio has been the worst backend to work with due to being both unintuitive and having almost no documentation +apart from comments in the headers (which admittedly are quite good). For my own purposes, and for anybody out there whose +needing to figure out how this darn thing works, I'm going to outline a few things here. + +Since miniaudio is a fairly low-level API, one of the things it needs is control over specific devices, and it needs to be +able to identify whether or not it can be used as playback and/or capture. The AudioObject API is the only one I've seen +that supports this level of detail. There was some public domain sample code I stumbled across that used the AudioComponent +and AudioUnit APIs, but I couldn't see anything that gave low-level control over device selection and capabilities (the +distinction between playback and capture in particular). Therefore, miniaudio is using the AudioObject API. + +Most (all?) functions in the AudioObject API take a AudioObjectID as it's input. This is the device identifier. When +retrieving global information, such as the device list, you use kAudioObjectSystemObject. When retrieving device-specific +data, you pass in the ID for that device. In order to retrieve device-specific IDs you need to enumerate over each of the +devices. This is done using the AudioObjectGetPropertyDataSize() and AudioObjectGetPropertyData() APIs which seem to be +the central APIs for retrieving information about the system and specific devices. + +To use the AudioObjectGetPropertyData() API you need to use the notion of a property address. A property address is a +structure with three variables and is used to identify which property you are getting or setting. The first is the "selector" +which is basically the specific property that you're wanting to retrieve or set. The second is the "scope", which is +typically set to kAudioObjectPropertyScopeGlobal, kAudioObjectPropertyScopeInput for input-specific properties and +kAudioObjectPropertyScopeOutput for output-specific properties. The last is the "element" which is always set to +kAudioObjectPropertyElementMain in miniaudio's case. I don't know of any cases where this would be set to anything different. + +Back to the earlier issue of device retrieval, you first use the AudioObjectGetPropertyDataSize() API to retrieve the size +of the raw data which is just a list of AudioDeviceID's. You use the kAudioObjectSystemObject AudioObjectID, and a property +address with the kAudioHardwarePropertyDevices selector and the kAudioObjectPropertyScopeGlobal scope. Once you have the +size, allocate a block of memory of that size and then call AudioObjectGetPropertyData(). The data is just a list of +AudioDeviceID's so just do "dataSize/sizeof(AudioDeviceID)" to know the device count. +*/ + +#if defined(MA_APPLE_MOBILE) +static void ma_device__on_notification_interruption_began(ma_device* pDevice) +{ + ma_device__on_notification(ma_device_notification_init(pDevice, ma_device_notification_type_interruption_began));

It is reproduced here in a slightly edited form for + convenience. + + A 65-character subset of US-ASCII is used, enabling 6 bits to be + represented per printable character. (The extra 65th character, "=", + is used to signify a special processing function.) + + The encoding process represents 24-bit groups of input bits as output + strings of 4 encoded characters. Proceeding from left to right, a + 24-bit input group is formed by concatenating 3 8-bit input groups. + These 24 bits are then treated as 4 concatenated 6-bit groups, each + of which is translated into a single digit in the base64 alphabet. + + Each 6-bit group is used as an index into an array of 64 printable + characters.

Be cautious here because +opening a port and let anyone connected execute arbitrary command on your +site is DANGEROUS. If you really need to do this, here is an example: +.Pp +On +.Sq server +side: +.Pp +.Dl $ rm -f /tmp/f; mkfifo /tmp/f +.Dl $ cat /tmp/f | /bin/sh -i 2>&1 | nc -l 127.0.0.1 1234 > /tmp/f +.Pp +On +.Sq client +side: +.Pp +.Dl $ nc host.example.com 1234 +.Dl $ (shell prompt from host.example.com) +.Pp +By doing this, you create a fifo at /tmp/f and make nc listen at port 1234 +of address 127.0.0.1 on +.Sq server +side, when a +.Sq client +establishes a connection successfully to that port, /bin/sh gets executed +on +.Sq server +side and the shell prompt is given to +.Sq client +side. +.Pp +When connection is terminated, +.Nm +quits as well. Use +.Fl k +if you want it keep listening, but if the command quits this option won't +restart it or keep +.Nm +running. Also don't forget to remove the file descriptor once you don't need +it anymore: +.Pp +.Dl $ rm -f /tmp/f +.Pp +.Sh DATA TRANSFER +The example in the previous section can be expanded to build a +basic data transfer model. +Any information input into one end of the connection will be output +to the other end, and input and output can be easily captured in order to +emulate file transfer. +.Pp +Start by using +.Nm +to listen on a specific port, with output captured into a file: +.Pp +.Dl $ nc -l 1234 > filename.out +.Pp +Using a second machine, connect to the listening +.Nm +process, feeding it the file which is to be transferred: +.Pp +.Dl $ nc -N host.example.com 1234 < filename.in +.Pp +After the file has been transferred, the connection will close automatically. +.Sh TALKING TO SERVERS +It is sometimes useful to talk to servers +.Dq by hand +rather than through a user interface. +It can aid in troubleshooting, +when it might be necessary to verify what data a server is sending +in response to commands issued by the client. +For example, to retrieve the home page of a web site: +.Bd -literal -offset indent +$ printf "GET / HTTP/1.0\er\en\er\en" | nc host.example.com 80 +.Ed +.Pp +Note that this also displays the headers sent by the web server. +They can be filtered, using a tool such as +.Xr sed 1 , +if necessary. +.Pp +More complicated examples can be built up when the user knows the format +of requests required by the server. +As another example, an email may be submitted to an SMTP server using: +.Bd -literal -offset indent +$ nc [\-C] localhost 25 << EOF +HELO host.example.com +MAIL FROM: +RCPT TO: +DATA +Body of email. +\&. +QUIT +EOF +.Ed +.Sh PORT SCANNING +It may be useful to know which ports are open and running services on +a target machine. +The +.Fl z +flag can be used to tell +.Nm +to report open ports, +rather than initiate a connection. Usually it's useful to turn on verbose +output to stderr by use this option in conjunction with +.Fl v +option. +.Pp +For example: +.Bd -literal -offset indent +$ nc \-zv host.example.com 20-30 +Connection to host.example.com 22 port [tcp/ssh] succeeded! +Connection to host.example.com 25 port [tcp/smtp] succeeded! +.Ed +.Pp +The port range was specified to limit the search to ports 20 \- 30, and is +scanned by increasing order (unless the +.Fl r +flag is set). +.Pp +You can also specify a list of ports to scan, for example: +.Bd -literal -offset indent +$ nc \-zv host.example.com http 20 22-23 +nc: connect to host.example.com 80 (tcp) failed: Connection refused +nc: connect to host.example.com 20 (tcp) failed: Connection refused +Connection to host.example.com port [tcp/ssh] succeeded! +nc: connect to host.example.com 23 (tcp) failed: Connection refused +.Ed +.Pp +The ports are scanned by the order you given (unless the +.Fl r +flag is set). +.Pp +Alternatively, it might be useful to know which server software +is running, and which versions. +This information is often contained within the greeting banners. +In order to retrieve these, it is necessary to first make a connection, +and then break the connection when the banner has been retrieved. +This can be accomplished by specifying a small timeout with the +.Fl w +flag, or perhaps by issuing a +.Qq Dv QUIT +command to the server: +.Bd -literal -offset indent +$ echo "QUIT" | nc host.example.com 20-30 +SSH-1.99-OpenSSH_3.6.1p2 +Protocol mismatch. +220 host.example.com IMS SMTP Receiver Version 0.84 Ready +.Ed +.Sh EXAMPLES +Open a TCP connection to port 42 of host.example.com, using port 31337 as +the source port, with a timeout of 5 seconds: +.Pp +.Dl $ nc -p 31337 -w 5 host.example.com 42 +.Pp +Open a UDP connection to port 53 of host.example.com: +.Pp +.Dl $ nc -u host.example.com 53 +.Pp +Open a TCP connection to port 42 of host.example.com using 10.1.2.3 as the +IP for the local end of the connection: +.Pp +.Dl $ nc -s 10.1.2.3 host.example.com 42 +.Pp +Create and listen on a +.Ux Ns -domain +stream socket: +.Pp +.Dl $ nc -lU /var/tmp/dsocket +.Pp +Connect to port 42 of host.example.com via an HTTP proxy at 10.2.3.4, +port 8080. +This example could also be used by +.Xr ssh 1 ; +see the +.Cm ProxyCommand +directive in +.Xr ssh_config 5 +for more information. +.Pp +.Dl $ nc -x10.2.3.4:8080 -Xconnect host.example.com 42 +.Pp +The same example again, this time enabling proxy authentication with username +.Dq ruser +if the proxy requires it: +.Pp +.Dl $ nc -x10.2.3.4:8080 -Xconnect -Pruser host.example.com 42 +.Sh SEE ALSO +.Xr cat 1 , +.Xr ssh 1 +.Sh AUTHORS +Original implementation by +.An *Hobbit* Aq Mt hobbit@avian.org . +.br +Rewritten with IPv6 support by +.An Eric Jackson Aq Mt ericj@monkey.org . +.br +Modified for Debian port by Aron Xu +.Aq aron@debian.org . +.Sh CAVEATS +UDP port scans using the +.Fl uz +combination of flags will always report success irrespective of +the target machine's state. +However, +in conjunction with a traffic sniffer either on the target machine +or an intermediary device, +the +.Fl uz +combination could be useful for communications diagnostics. +Note that the amount of UDP traffic generated may be limited either +due to hardware resources and/or configuration settings. diff --git a/third_party/netcat/netcat.c b/third_party/netcat/netcat.c new file mode 100644 index 000000000..bca0ee7d2 --- /dev/null +++ b/third_party/netcat/netcat.c @@ -0,0 +1,2357 @@ +/* $OpenBSD: netcat.c,v 1.226 2023/08/14 08:07:27 tb Exp $ */ + +/* + * Copyright (c) 2001 Eric Jackson + * Copyright (c) 2015 Bob Beck.

It's also interesting + * that our command only needs 18mb of peak RSS memory, whereas Info-ZIP + * consumes 198 megabytes. Lastly, our archive comes out 500kb smaller. + * + * Alternatively, I could have used `zip -ry4` which takes 16 seconds, + * or `zip -ry1` which 11 seconds. The issue is then the cosmocc archive + * sizes would be 440mb and 469mb. However it's important to use maximum + * compression when generating permanent release artifacts, that will + * need to be stored on multiple servers forever, and downloaded by + * thousands of people. + * + * Another benefit of this tool is it produces deterministic output. + * When running in `-r` (recursive) mode, the standard `zip` command + * orders files in the archive based on the undefined order readdir() + * returns names from the operating system. That's bad if your build + * system needs to create zip files, since you'll get different results + * on different OSes. What this tool does instead, is it'll order names + * the same as the argument list by default. The exception is when the + * `-r` or `-S` flag is passed. In that case, appended zip names are + * sorted. Furthermore, the modified time is always set to 2025-03-22 + * and chmod bits are normalized to only include the execute bit, unless + * the `-N` flag is passed for nondeterministic mode. + * + * It's worth noting that this tool treats the output archive as an + * append-only database. For example, the following commands: + * + * fasterzip archive.zip x.txt + * fasterzip archive.zip y.txt + * fasterzip archive.zip x.txt + * + * Will produce a zip file that officially has two files, where x.txt + * contains the most recent content. However the binary content in the + * archive.zip file still contains the data for the previous revision of + * x.txt that was added first. The previous version of the zip central + * directory is also preserved. However it's currently not possible to + * access that information without writing a custom tool. + * + * The benefit to this approach is that new content can be added much + * quicker than the traditional `zip` command, which rebuilds the entire + * archive every time entries are inserted or removed. This is useful + * when using .zip files for huge content like language models weights. + * However the drawback is it makes the .zip file bigger, unless the + * archive is rebuilt from scratch. + * + * Another powerful feature this tool offers is the ability to align + * file content. With large files like LLM weights, it is sometimes + * desirable to be able to use mmap() to load them into memory. To make + * it possible, the `-0 -a 65536` flags may be passed to store without + * compression and guarantee alignment on any system page size. + */ + +static const char *const help = "\ +Copyright 2025 Justine Alexandra Roberts Tunney - ISC license\n\ +FasterZIP 1.0 (2025-03-21).
