# Most of the code from this point onwards is related to populating the
# following variables:
# PA_PUBLIC_INCLUDES - This contains the list of public PortAudio header
# files. These files will be copied into /include paths on Unix'y
# systems when "make install" is invoked.
# PA_PRIVATE_INCLUDES - This contains the list of header files which
# are not part of PortAudio, but are required by the various hostapis.
# It is only used by CMake IDE generators (like Visual Studio) to
# provide quick-links to useful headers. It has no impact on build
# output.
# PA_PRIVATE_INCLUDE_PATHS - This contains the list of include paths which
# will be passed to the compiler while PortAudio is being built which
# are not required by applications using the PortAudio API.
# PA_PRIVATE_COMPILE_DEFINITIONS - This contains a list of preprocessor
# macro definitions which will be set when compiling PortAudio source
# files.
# PA_SOURCES - This contains the list of source files which will be built
# into the static and shared PortAudio libraries.
# PA_NON_UNICODE_SOURCES - This also contains a list of source files which
# will be build into the static and shared PortAudio libraries. However,
# these sources will not have any unicode compiler definitions added
# to them. This list should only contain external source dependencies.
# PA_EXTRA_SHARED_SOURCES - Contains a list of extra files which will be
# associated only with the shared PortAudio library. This only seems
# relevant for Windows shared libraries which require a list of export
# symbols.
# Where other PA_* variables are set, these are almost always only used to
# preserve the historic SOURCE_GROUP behavior (which again only has an impact
# on IDE-style generators for visual appearance) or store the output of
# find_library() calls.

# PortAudio - portable audio I/O library
PortAudio is a portable audio I/O library designed for cross-platform
support of audio. It uses either a callback mechanism to request audio
processing, or blocking read/write calls to buffer data between the
native audio subsystem and the client. Audio can be processed in various
formats, including 32 bit floating point, and will be converted to the
native format internally.
## Documentation:
* Documentation is available at http://www.portaudio.com/docs/
* Or at `/doc/html/index.html` after running Doxygen.
* Also see `src/common/portaudio.h` for the API spec.
* And see the `examples/` and `test/` directories for many examples of usage. (We suggest `examples/paex_saw.c` for an example.)
For information on compiling programs with PortAudio, please see the
tutorial at:
http://portaudio.com/docs/v19-doxydocs/tutorial_start.html
We have an active mailing list for user and developer discussions.
Please feel free to join. See http://www.portaudio.com for details.
## Important Files and Folders:
include/portaudio.h = header file for PortAudio API. Specifies API.
src/common/ = platform independent code, host independent
code for all implementations.
src/os = os specific (but host api neutral) code
src/hostapi = implementations for different host apis
### Host API Implementations:
src/hostapi/alsa = Advanced Linux Sound Architecture (ALSA)
src/hostapi/asihpi = AudioScience HPI
src/hostapi/asio = ASIO for Windows and Macintosh
src/hostapi/coreaudio = Macintosh Core Audio for OS X
src/hostapi/dsound = Windows Direct Sound
src/hostapi/jack = JACK Audio Connection Kit
src/hostapi/oss = Unix Open Sound System (OSS)
src/hostapi/wasapi = Windows Vista WASAPI
src/hostapi/wdmks = Windows WDM Kernel Streaming
src/hostapi/wmme = Windows MultiMedia Extensions (MME)
### Test Programs:
test/pa_fuzz.c = guitar fuzz box
test/pa_devs.c = print a list of available devices
test/pa_minlat.c = determine minimum latency for your machine
test/paqa_devs.c = self test that opens all devices
test/paqa_errs.c = test error detection and reporting
test/patest_clip.c = hear a sine wave clipped and unclipped
test/patest_dither.c = hear effects of dithering (extremely subtle)
test/patest_pink.c = fun with pink noise
test/patest_record.c = record and playback some audio
test/patest_maxsines.c = how many sine waves can we play? Tests Pa_GetCPULoad().
test/patest_sine.c = output a sine wave in a simple PA app
test/patest_sync.c = test synchronization of audio and video
test/patest_wire.c = pass input to output, wire simulator

/*
IMPORTANT:
WASAPI is implemented for Callback and Blocking interfaces. It supports Shared and Exclusive
share modes.
Exclusive Mode:
Exclusive mode allows to deliver audio data directly to hardware bypassing
software mixing.
Exclusive mode is specified by 'paWinWasapiExclusive' flag.
Callback Interface:
Provides best audio quality with low latency. Callback interface is implemented in
two versions:
1) Event-Driven:
This is the most powerful WASAPI implementation which provides glitch-free
audio at around 3ms latency in Exclusive mode. Lowest possible latency for this mode is
3 ms for HD Audio class audio chips. For the Shared mode latency can not be
lower than 20 ms.
2) Poll-Driven:
Polling is another 2-nd method to operate with WASAPI. It is less efficient than Event-Driven
and provides latency at around 10-13ms. Polling must be used to overcome a system bug
under Windows Vista x64 when application is WOW64(32-bit) and Event-Driven method simply
times out (event handle is never signalled on buffer completion). Please note, such WOW64 bug
does not exist in Vista x86 or Windows 7.
Polling can be setup by specifying 'paWinWasapiPolling' flag. Our WASAPI implementation detects
WOW64 bug and sets 'paWinWasapiPolling' automatically.
Thread priority:
Normally thread priority is set automatically and does not require modification. Although
if user wants some tweaking thread priority can be modified by setting 'paWinWasapiThreadPriority'
flag and specifying 'PaWasapiStreamInfo::threadPriority' with value from PaWasapiThreadPriority
enum.
Blocking Interface:
Blocking interface is implemented but due to above described Poll-Driven method can not
deliver lowest possible latency. Specifying too low latency in Shared mode will result in
distorted audio although Exclusive mode adds stability.
8.24 format:
If paCustomFormat is specified as sample format then the implementation will understand it
as valid 24-bits inside 32-bit container (e.g. wBitsPerSample = 32, Samples.wValidBitsPerSample = 24).
By using paCustomFormat there will be small optimization when samples are be copied
with Copy_24_To_24 by PA processor instead of conversion from packed 3-byte (24-bit) data
with Int24_To_Int32.
Pa_IsFormatSupported:
To check format with correct Share Mode (Exclusive/Shared) you must supply PaWasapiStreamInfo
with flags paWinWasapiExclusive set through member of PaStreamParameters::hostApiSpecificStreamInfo
structure.
If paWinWasapiExplicitSampleFormat flag is provided then implementation will not try to select
suitable close format and will return an error instead of paFormatIsSupported. By specifying
paWinWasapiExplicitSampleFormat flag it is possible to find out what sample formats are
supported by Exclusive or Shared modes.
Pa_OpenStream:
To set desired Share Mode (Exclusive/Shared) you must supply
PaWasapiStreamInfo with flags paWinWasapiExclusive set through member of
PaStreamParameters::hostApiSpecificStreamInfo structure.
Coding style for parameters and structure members of the public API:
1) bXXX - boolean, [1 (TRUE), 0 (FALSE)]
2) pXXX - pointer
3) fnXXX - pointer to function
4) structure members are never prefixed with a type distinguisher
UWP/WinRT:
This platform has number of limitations which do not allow to enumerate audio devices without
an additional external help. Enumeration is possible though from C++/CX, check the related API
Windows::Devices::Enumeration::DeviceInformation::FindAllAsync().
The main limitation is an absence of the device enumeration from inside the PA's implementation.
This problem can be solved by using the following functions:
PaWasapiWinrt_SetDefaultDeviceId() - to set default input/output device,
PaWasapiWinrt_PopulateDeviceList() - to populate device list with devices.
Here is an example of populating the device list which can also be updated dynamically depending on
whether device was removed from or added to the system:
----------------
std::vector<const UINT16 *> ids, names;
std::vector<PaWasapiDeviceRole> role;
ids.resize(count);
names.resize(count);
role.resize(count);
for (UINT32 i = 0; i < count; ++i)
{
ids[i] = (const UINT16 *)device_ids[i].c_str();
names[i] = (const UINT16 *)device_names[i].c_str();
role[i] = eRoleUnknownFormFactor;
}
PaWasapiWinrt_SetDefaultDeviceId((const UINT16 *)default_device_id.c_str(), !capture);
PaWasapiWinrt_PopulateDeviceList(ids.data(), names.data(), role.data(), count, !capture);
PaWasapi_UpdateDeviceList();
----------------

/*Noise shaped dither (March 2000)
-------------------
This is a simple implementation of highpass triangular-PDF dither with
2nd-order noise shaping, for use when truncating floating point audio
data to fixed point.
The noise shaping lowers the noise floor by 11dB below 5kHz (@ 44100Hz
sample rate) compared to triangular-PDF dither. The code below assumes
input data is in the range +1 to -1 and doesn't check for overloads!
To save time when generating dither for multiple channels you can do
things like this: r3=(r1 & 0x7F)<<8; instead of calling rand() again.
int r1, r2; //rectangular-PDF random numbers
float s1, s2; //error feedback buffers
float s = 0.5f; //set to 0.0f for no noise shaping
float w = pow(2.0,bits-1); //word length (usually bits=16)
float wi= 1.0f/w;
float d = wi / RAND_MAX; //dither amplitude (2 lsb)
float o = wi * 0.5f; //remove dc offset
float in, tmp;
int out;
//for each sample...
r2=r1; //can make HP-TRI dither by
r1=rand(); //subtracting previous rand()
in += s * (s1 + s1 - s2); //error feedback
tmp = in + o + d * (float)(r1 - r2); //dc offset and dither
out = (int)(w * tmp); //truncate downwards
if(tmp<0.0f) out--; //this is faster than floor()
s2 = s1;
s1 = in - wi * (float)out; //error

16-to-8-bit first-order dither
Type : First order error feedforward dithering code
References : Posted by Jon Watte
Notes :
This is about as simple a dithering algorithm as you can implement, but it's
likely to sound better than just truncating to N bits.
Note that you might not want to carry forward the full difference for infinity.
It's probably likely that the worst performance hit comes from the saturation
conditionals, which can be avoided with appropriate instructions on many DSPs
and integer SIMD type instructions, or CMOV.
Last, if sound quality is paramount (such as when going from > 16 bits to 16
bits) you probably want to use a higher-order dither function found elsewhere
on this site.
Code :
// This code will down-convert and dither a 16-bit signed short
// mono signal into an 8-bit unsigned char signal, using a first
// order forward-feeding error term dither.
#define uchar unsigned char
void dither_one_channel_16_to_8( short * input, uchar * output, int count, int * memory )
{
int m = *memory;
while( count-- > 0 ) {
int i = *input++;
i += m;
int j = i + 32768 - 128;
uchar o;
if( j < 0 ) {
o = 0;
}
else if( j > 65535 ) {
o = 255;
}
else {
o = (uchar)((j>>8)&0xff);
}
m = ((j-32768+128)-i);
*output++ = o;
}
*memory = m;
}

/** @file
@ingroup common_src
@brief Buffer Processor prototypes. A Buffer Processor performs buffer length
adaption, coordinates sample format conversion, and interleaves/deinterleaves
channels.
<h3>Overview</h3>
The "Buffer Processor" (PaUtilBufferProcessor) manages conversion of audio
data from host buffers to user buffers and back again. Where required, the
buffer processor takes care of converting between host and user sample formats,
interleaving and deinterleaving multichannel buffers, and adapting between host
and user buffers with different lengths. The buffer processor may be used with
full and half duplex streams, for both callback streams and blocking read/write
streams.
One of the important capabilities provided by the buffer processor is
the ability to adapt between user and host buffer sizes of different lengths
with minimum latency. Although this task is relatively easy to perform when
the host buffer size is an integer multiple of the user buffer size, the
problem is more complicated when this is not the case - especially for
full-duplex callback streams. Where necessary the adaption is implemented by
internally buffering some input and/or output data. The buffer adation
algorithm used by the buffer processor was originally implemented by
Stephan Letz for the ASIO version of PortAudio, and is described in his
Callback_adaption_.pdf which is included in the distribution.
The buffer processor performs sample conversion using the functions provided
by pa_converters.c.
The following sections provide an overview of how to use the buffer processor.
Interested readers are advised to consult the host API implementations for
examples of buffer processor usage.
<h4>Initialization, resetting and termination</h4>
When a stream is opened, the buffer processor should be initialized using
PaUtil_InitializeBufferProcessor. This function initializes internal state
and allocates temporary buffers as necessary according to the supplied
configuration parameters. Some of the parameters correspond to those requested
by the user in their call to Pa_OpenStream(), others reflect the requirements
of the host API implementation - they indicate host buffer sizes, formats,
and the type of buffering which the Host API uses. The buffer processor should
be initialized for callback streams and blocking read/write streams.
Call PaUtil_ResetBufferProcessor to clear any sample data which is present
in the buffer processor before starting to use it (for example when
Pa_StartStream is called).
When the buffer processor is no longer used call
PaUtil_TerminateBufferProcessor.
<h4>Using the buffer processor for a callback stream</h4>
The buffer processor's role in a callback stream is to take host input buffers
process them with the stream callback, and fill host output buffers. For a
full duplex stream, the buffer processor handles input and output simultaneously
due to the requirements of the minimum-latency buffer adation algorithm.
When a host buffer becomes available, the implementation should call
the buffer processor to process the buffer. The buffer processor calls the
stream callback to consume and/or produce audio data as necessary. The buffer
processor will convert sample formats, interleave/deinterleave channels,
and slice or chunk the data to the appropriate buffer lengths according to
the requirements of the stream callback and the host API.
To process a host buffer (or a pair of host buffers for a full-duplex stream)
use the following calling sequence:
-# Call PaUtil_BeginBufferProcessing
-# For a stream which takes input:
- Call PaUtil_SetInputFrameCount with the number of frames in the host input
buffer.
- Call one of the following functions one or more times to tell the
buffer processor about the host input buffer(s): PaUtil_SetInputChannel,
PaUtil_SetInterleavedInputChannels, PaUtil_SetNonInterleavedInputChannel.
Which function you call will depend on whether the host buffer(s) are
interleaved or not.
- If the available host data is split across two buffers (for example a
data range at the end of a circular buffer and another range at the
beginning of the circular buffer), also call
PaUtil_Set2ndInputFrameCount, PaUtil_Set2ndInputChannel,
PaUtil_Set2ndInterleavedInputChannels,
PaUtil_Set2ndNonInterleavedInputChannel as necessary to tell the buffer
processor about the second buffer.
-# For a stream which generates output:
- Call PaUtil_SetOutputFrameCount with the number of frames in the host
output buffer.
- Call one of the following functions one or more times to tell the
buffer processor about the host output buffer(s): PaUtil_SetOutputChannel,
PaUtil_SetInterleavedOutputChannels, PaUtil_SetNonInterleavedOutputChannel.
Which function you call will depend on whether the host buffer(s) are
interleaved or not.
- If the available host output buffer space is split across two buffers
(for example a data range at the end of a circular buffer and another
range at the beginning of the circular buffer), call
PaUtil_Set2ndOutputFrameCount, PaUtil_Set2ndOutputChannel,
PaUtil_Set2ndInterleavedOutputChannels,
PaUtil_Set2ndNonInterleavedOutputChannel as necessary to tell the buffer
processor about the second buffer.
-# Call PaUtil_EndBufferProcessing, this function performs the actual data
conversion and processing.
<h4>Using the buffer processor for a blocking read/write stream</h4>
Blocking read/write streams use the buffer processor to convert and copy user
output data to a host buffer, and to convert and copy host input data to
the user's buffer. The buffer processor does not perform any buffer adaption.
When using the buffer processor in a blocking read/write stream the input and
output conversion are performed separately by the PaUtil_CopyInput and
PaUtil_CopyOutput functions.
To copy data from a host input buffer to the buffer(s) which the user supplies
to Pa_ReadStream, use the following calling sequence.
- Repeat the following three steps until the user buffer(s) have been filled
with samples from the host input buffers:
-# Call PaUtil_SetInputFrameCount with the number of frames in the host
input buffer.
-# Call one of the following functions one or more times to tell the
buffer processor about the host input buffer(s): PaUtil_SetInputChannel,
PaUtil_SetInterleavedInputChannels, PaUtil_SetNonInterleavedInputChannel.
Which function you call will depend on whether the host buffer(s) are
interleaved or not.
-# Call PaUtil_CopyInput with the user buffer pointer (or a copy of the
array of buffer pointers for a non-interleaved stream) passed to
Pa_ReadStream, along with the number of frames in the user buffer(s).
Be careful to pass a <i>copy</i> of the user buffer pointers to
PaUtil_CopyInput because PaUtil_CopyInput advances the pointers to
the start of the next region to copy.
- PaUtil_CopyInput will not copy more data than is available in the
host buffer(s), so the above steps need to be repeated until the user
buffer(s) are full.
To copy data to the host output buffer from the user buffers(s) supplied
to Pa_WriteStream use the following calling sequence.
- Repeat the following three steps until all frames from the user buffer(s)
have been copied to the host API:
-# Call PaUtil_SetOutputFrameCount with the number of frames in the host
output buffer.
-# Call one of the following functions one or more times to tell the
buffer processor about the host output buffer(s): PaUtil_SetOutputChannel,
PaUtil_SetInterleavedOutputChannels, PaUtil_SetNonInterleavedOutputChannel.
Which function you call will depend on whether the host buffer(s) are
interleaved or not.
-# Call PaUtil_CopyOutput with the user buffer pointer (or a copy of the
array of buffer pointers for a non-interleaved stream) passed to
Pa_WriteStream, along with the number of frames in the user buffer(s).
Be careful to pass a <i>copy</i> of the user buffer pointers to
PaUtil_CopyOutput because PaUtil_CopyOutput advances the pointers to
the start of the next region to copy.
- PaUtil_CopyOutput will not copy more data than fits in the host buffer(s),
so the above steps need to be repeated until all user data is copied.

/** @file

@brief Single-reader single-writer lock-free ring buffer
PaUtilRingBuffer is a ring buffer used to transport samples between
different execution contexts (threads, OS callbacks, interrupt handlers)
without requiring the use of any locks. This only works when there is
a single reader and a single writer (ie. one thread or callback writes
to the ring buffer, another thread or callback reads from it).
The PaUtilRingBuffer structure manages a ring buffer containing N
elements, where N must be a power of two. An element may be any size
(specified in bytes).
The memory area used to store the buffer elements must be allocated by
the client prior to calling PaUtil_InitializeRingBuffer() and must outlive
the use of the ring buffer.
@note The ring buffer functions are not normally exposed in the PortAudio libraries.
If you want to call them then you will need to add pa_ringbuffer.c to your application source code.

ASIO-README.txt
This document contains information to help you compile PortAudio with
ASIO support. If you find any omissions or errors in this document
please notify us on the PortAudio mailing list.
NOTE: The Macintosh sections of this document are provided for historical
reference. They refer to pre-OS X Macintosh. PortAudio no longer
supports pre-OS X Macintosh. Steinberg does not support ASIO on Mac OS X.
Building PortAudio with ASIO support
------------------------------------
To build PortAudio with ASIO support you need to compile and link with
pa_asio.c, and files from the ASIO SDK (see below), along with the common
PortAudio files from src/common/ and platform specific files from
src/os/win/ (for Win32).
If you are compiling with a non-Microsoft compiler on Windows, also
compile and link with iasiothiscallresolver.cpp (see below for
an explanation).
For some platforms (MingW, Cygwin/MingW), you may simply
be able to type:
./configure --with-host_os=mingw --with-winapi=asio [--with-asiodir=/usr/local/asiosdk2]
make
and life will be good. Make sure you update the above with the correct local
path to the ASIO SDK.
For Microsoft Visual C++ there is an build tutorial here:
http://www.portaudio.com/trac/wiki/TutorialDir/Compile/WindowsASIOMSVC
Obtaining the ASIO SDK
----------------------
In order to build PortAudio with ASIO support, you need to download
the ASIO SDK (version 2.0 or later) from Steinberg. Steinberg makes the ASIO
SDK available to anyone free of charge, however they do not permit its
source code to be distributed.
NOTE: In some cases the ASIO SDK may require patching, see below
for further details.
http://www.steinberg.net/en/company/developer.html
If the above link is broken search Google for:
"download steinberg ASIO SDK"
Building the ASIO SDK on Windows
--------------------------------
To build the ASIO SDK on Windows you need to compile and link with the
following files from the ASIO SDK:
asio_sdk\common\asio.cpp
asio_sdk\host\asiodrivers.cpp
asio_sdk\host\pc\asiolist.cpp
You may also need to adjust your include paths to support inclusion of
header files from the above directories.
The ASIO SDK depends on the following COM API functions:
CoInitialize, CoUninitialize, CoCreateInstance, CLSIDFromString
For compilation with MinGW you will need to link with -lole32, for
Borland compilers link with Import32.lib.
Non-Microsoft (MSVC) Compilers on Windows including Borland and GCC
-------------------------------------------------------------------
Steinberg did not specify a calling convention in the IASIO interface
definition. This causes the Microsoft compiler to use the proprietary
thiscall convention which is not compatible with other compilers, such
as compilers from Borland (BCC and C++Builder) and GNU (gcc).
Steinberg's ASIO SDK will compile but crash on initialization if
compiled with a non-Microsoft compiler on Windows.
PortAudio solves this problem using the iasiothiscallresolver library
which is included in the distribution. When building ASIO support for
non-Microsoft compilers, be sure to compile and link with
iasiothiscallresolver.cpp. Note that iasiothiscallresolver includes
conditional directives which cause it to have no effect if it is
compiled with a Microsoft compiler, or on the Macintosh.
If you use configure and make (see above), this should be handled
automatically for you.
For further information about the IASIO thiscall problem see this page:
http://www.rossbencina.com/code/iasio-thiscall-resolver
Building the ASIO SDK on (Pre-OS X) Macintosh
---------------------------------------------
To build the ASIO SDK on Macintosh you need to compile and link with the
following files from the ASIO SDK:
host/asiodrivers.cpp
host/mac/asioshlib.cpp
host/mac/codefragements.cpp
You may also need to adjust your include paths to support inclusion of
header files from the above directories.
(Pre-OS X) Macintosh ASIO SDK Bug Patch
---------------------------------------
There is a bug in the ASIO SDK that causes the Macintosh version to
often fail during initialization. Below is a patch that you can apply.
In codefragments.cpp replace getFrontProcessDirectory function with
the following one (GetFrontProcess replaced by GetCurrentProcess).
bool CodeFragments::getFrontProcessDirectory(void *specs)
{
FSSpec *fss = (FSSpec *)specs;
ProcessInfoRec pif;
ProcessSerialNumber psn;
memset(&psn,0,(long)sizeof(ProcessSerialNumber));
// if(GetFrontProcess(&psn) == noErr) // wrong !!!
if(GetCurrentProcess(&psn) == noErr) // correct !!!
{
pif.processName = 0;
pif.processAppSpec = fss;
pif.processInfoLength = sizeof(ProcessInfoRec);
if(GetProcessInformation(&psn, &pif) == noErr)
return true;
}
return false;
}

/*
IASIOThiscallResolver.cpp see the comments in iasiothiscallresolver.h for
the top level description - this comment describes the technical details of
the implementation.
The latest version of this file is available from:
http://www.audiomulch.com/~rossb/code/calliasio
please email comments to Ross Bencina <rossb@audiomulch.com>
BACKGROUND
The IASIO interface declared in the Steinberg ASIO 2 SDK declares
functions with no explicit calling convention. This causes MSVC++ to default
to using the thiscall convention, which is a proprietary convention not
implemented by some non-microsoft compilers - notably borland BCC,
C++Builder, and gcc. MSVC++ is the defacto standard compiler used by
Steinberg. As a result of this situation, the ASIO sdk will compile with
any compiler, however attempting to execute the compiled code will cause a
crash due to different default calling conventions on non-Microsoft
compilers.
IASIOThiscallResolver solves the problem by providing an adapter class that
delegates to the IASIO interface using the correct calling convention
(thiscall). Due to the lack of support for thiscall in the Borland and GCC
compilers, the calls have been implemented in assembly language.
A number of macros are defined for thiscall function calls with different
numbers of parameters, with and without return values - it may be possible
to modify the format of these macros to make them work with other inline
assemblers.
THISCALL DEFINITION
A number of definitions of the thiscall calling convention are floating
around the internet. The following definition has been validated against
output from the MSVC++ compiler:
For non-vararg functions, thiscall works as follows: the object (this)
pointer is passed in ECX. All arguments are passed on the stack in
right to left order. The return value is placed in EAX. The callee
clears the passed arguments from the stack.
FINDING FUNCTION POINTERS FROM AN IASIO POINTER
The first field of a COM object is a pointer to its vtble. Thus a pointer
to an object implementing the IASIO interface also points to a pointer to
that object's vtbl. The vtble is a table of function pointers for all of
the virtual functions exposed by the implemented interfaces.
If we consider a variable declared as a pointer to IASO:
IASIO *theAsioDriver
theAsioDriver points to:
object implementing IASIO
{
IASIOvtbl *vtbl
other data
}
in other words, theAsioDriver points to a pointer to an IASIOvtbl
vtbl points to a table of function pointers:
IASIOvtbl ( interface IASIO : public IUnknown )
{
(IUnknown functions)
0 virtual HRESULT STDMETHODCALLTYPE (*QueryInterface)(REFIID riid, void **ppv) = 0;
4 virtual ULONG STDMETHODCALLTYPE (*AddRef)() = 0;
8 virtual ULONG STDMETHODCALLTYPE (*Release)() = 0;
(IASIO functions)
12 virtual ASIOBool (*init)(void *sysHandle) = 0;
16 virtual void (*getDriverName)(char *name) = 0;
20 virtual long (*getDriverVersion)() = 0;
24 virtual void (*getErrorMessage)(char *string) = 0;
28 virtual ASIOError (*start)() = 0;
32 virtual ASIOError (*stop)() = 0;
36 virtual ASIOError (*getChannels)(long *numInputChannels, long *numOutputChannels) = 0;
40 virtual ASIOError (*getLatencies)(long *inputLatency, long *outputLatency) = 0;
44 virtual ASIOError (*getBufferSize)(long *minSize, long *maxSize,
long *preferredSize, long *granularity) = 0;
48 virtual ASIOError (*canSampleRate)(ASIOSampleRate sampleRate) = 0;
52 virtual ASIOError (*getSampleRate)(ASIOSampleRate *sampleRate) = 0;
56 virtual ASIOError (*setSampleRate)(ASIOSampleRate sampleRate) = 0;
60 virtual ASIOError (*getClockSources)(ASIOClockSource *clocks, long *numSources) = 0;
64 virtual ASIOError (*setClockSource)(long reference) = 0;
68 virtual ASIOError (*getSamplePosition)(ASIOSamples *sPos, ASIOTimeStamp *tStamp) = 0;
72 virtual ASIOError (*getChannelInfo)(ASIOChannelInfo *info) = 0;
76 virtual ASIOError (*createBuffers)(ASIOBufferInfo *bufferInfos, long numChannels,
long bufferSize, ASIOCallbacks *callbacks) = 0;
80 virtual ASIOError (*disposeBuffers)() = 0;
84 virtual ASIOError (*controlPanel)() = 0;
88 virtual ASIOError (*future)(long selector,void *opt) = 0;
92 virtual ASIOError (*outputReady)() = 0;
};
The numbers in the left column show the byte offset of each function ptr
from the beginning of the vtbl. These numbers are used in the code below
to select different functions.
In order to find the address of a particular function, theAsioDriver
must first be dereferenced to find the value of the vtbl pointer:
mov eax, theAsioDriver
mov edx, [theAsioDriver] // edx now points to vtbl[0]
Then an offset must be added to the vtbl pointer to select a
particular function, for example vtbl+44 points to the slot containing
a pointer to the getBufferSize function.
Finally vtbl+x must be dereferenced to obtain the value of the function
pointer stored in that address:
call [edx+44] // call the function pointed to by
// the value in the getBufferSize field of the vtbl
SEE ALSO
Martin Fay's OpenASIO DLL at http://www.martinfay.com solves the same
problem by providing a new COM interface which wraps IASIO with an
interface that uses portable calling conventions. OpenASIO must be compiled
with MSVC, and requires that you ship the OpenASIO DLL with your
application.
ACKNOWLEDGEMENTS
Ross Bencina: worked out the thiscall details above, wrote the original
Borland asm macros, and a patch for asio.cpp (which is no longer needed).
Thanks to Martin Fay for introducing me to the issues discussed here,
and to Rene G. Ceballos for assisting with asm dumps from MSVC++.
Antti Silvast: converted the original calliasio to work with gcc and NASM
by implementing the asm code in a separate file.
Fraser Adams: modified the original calliasio containing the Borland inline
asm to add inline asm for gcc i.e. Intel syntax for Borland and AT&T syntax
for gcc. This seems a neater approach for gcc than to have a separate .asm
file and it means that we only need one version of the thiscall patch.
Fraser Adams: rewrote the original calliasio patch in the form of the
IASIOThiscallResolver class in order to avoid modifications to files from
the Steinberg SDK, which may have had potential licence issues.

recent versions of the gcc assembler.

// ****************************************************************************
// File: IASIOThiscallResolver.h
// Description: The IASIOThiscallResolver class implements the IASIO
// interface and acts as a proxy to the real IASIO interface by
// calling through its vptr table using the thiscall calling
// convention. To put it another way, we interpose
// IASIOThiscallResolver between ASIO SDK code and the driver.
// This is necessary because most non-Microsoft compilers don't
// implement the thiscall calling convention used by IASIO.
//
// iasiothiscallresolver.cpp contains the background of this
// problem plus a technical description of the vptr
// manipulations.
//
// In order to use this mechanism one simply has to add
// iasiothiscallresolver.cpp to the list of files to compile
// and #include <iasiothiscallresolver.h>
//
// Note that this #include must come after the other ASIO SDK
// #includes, for example:
//
// #include <windows.h>
// #include <asiosys.h>
// #include <asio.h>
// #include <asiodrivers.h>
// #include <iasiothiscallresolver.h>
//
// Actually the important thing is to #include
// <iasiothiscallresolver.h> after <asio.h>. We have
// incorporated a test to enforce this ordering.
//
// The code transparently takes care of the interposition by
// using macro substitution to intercept calls to ASIOInit()
// and ASIOExit(). We save the original ASIO global
// "theAsioDriver" in our "that" variable, and then set
// "theAsioDriver" to equal our IASIOThiscallResolver instance.
//
// Whilst this method of resolving the thiscall problem requires
// the addition of #include <iasiothiscallresolver.h> to client
// code it has the advantage that it does not break the terms
// of the ASIO licence by publishing it. We are NOT modifying
// any Steinberg code here, we are merely implementing the IASIO
// interface in the same way that we would need to do if we
// wished to provide an open source ASIO driver.
//
// For compilation with MinGW -lole32 needs to be added to the
// linker options. For BORLAND, linking with Import32.lib is
// sufficient.
//
// The dependencies are with: CoInitialize, CoUninitialize,
// CoCreateInstance, CLSIDFromString - used by asiolist.cpp
// and are required on Windows whether ThiscallResolver is used
// or not.
//
// Searching for the above strings in the root library path
// of your compiler should enable the correct libraries to be
// identified if they aren't immediately obvious.
//
// Note that the current implementation of IASIOThiscallResolver
// is not COM compliant - it does not correctly implement the
// IUnknown interface. Implementing it is not necessary because
// it is not called by parts of the ASIO SDK which call through
// theAsioDriver ptr. The IUnknown methods are implemented as
// assert(false) to ensure that the code fails if they are
// ever called.
// Restrictions: None. Public Domain & Open Source distribute freely
// You may use IASIOThiscallResolver commercially as well as
// privately.
// You the user assume the responsibility for the use of the
// files, binary or text, and there is no guarantee or warranty,
// expressed or implied, including but not limited to the
// implied warranties of merchantability and fitness for a
// particular purpose. You assume all responsibility and agree
// to hold no entity, copyright holder or distributors liable
// for any loss of data or inaccurate representations of data
// as a result of using IASIOThiscallResolver.
// Version: 1.4 Added separate macro CALL_THISCALL_1_DOUBLE from
// Andrew Baldwin, and volatile for whole gcc asm blocks,
// both for compatibility with newer gcc versions. Cleaned up
// Borland asm to use one less register.
// 1.3 Switched to including assert.h for better compatibility.
// Wrapped entire .h and .cpp contents with a check for
// _MSC_VER to provide better compatibility with MS compilers.
// Changed Singleton implementation to use static instance
// instead of freestore allocated instance. Removed ASIOExit
// macro as it is no longer needed.
// 1.2 Removed semicolons from ASIOInit and ASIOExit macros to
// allow them to be embedded in expressions (if statements).
// Cleaned up some comments. Removed combase.c dependency (it
// doesn't compile with BCB anyway) by stubbing IUnknown.
// 1.1 Incorporated comments from Ross Bencina including things
// such as changing name from ThiscallResolver to
// IASIOThiscallResolver, tidying up the constructor, fixing
// a bug in IASIOThiscallResolver::ASIOExit() and improving
// portability through the use of conditional compilation

Notes on status of CoreAudio Implementation of PortAudio
Document Last Updated December 9, 2005
There are currently two implementations of PortAudio for Mac Core Audio.
The original is in pa_mac_core_old.c, and the newer, default implementation
is in pa_mac_core.c.
Only pa_mac_core.c is currently developed and supported as it uses apple's
current core audio technology. To select use the old implementation, replace
pa_mac_core.c with pa_mac_core_old.c (eg. "cp pa_mac_core_auhal.c
pa_mac_core.c"), then run configure and make as usual.
-------------------------------------------
Notes on Newer/Default AUHAL implementation:
by Bjorn Roche
Last Updated December 9, 2005
Principle of Operation:
This implementation uses AUHAL for audio I/O. To some extent, it also
operates at the "HAL" Layer, though this behavior can be limited by
platform specific flags (see pa_mac_core.h for details). The default
settings should be reasonable: they don't change the SR of the device and
don't cause interruptions if other devices are using the device.
Major Software Elements Used: Apple's HAL AUs provide output SR
conversion transparently, however, only on output, so this
implementation uses AudioConverters to convert the sample rate on input.
A PortAudio ring buffer is used to buffer input when sample rate
conversion is required or when separate audio units are used for duplex
IO. Finally, a PortAudio buffer processor is used to convert formats and
provide additional buffers if needed. Internally, interleaved floating
point data streams are used exclusively - the audio unit converts from
the audio hardware's native format to interleaved float PCM and
PortAudio's Buffer processor is used for conversion to user formats.
Simplex Input: Simplex input uses a single callback. If sample rate
conversion is required, a ring buffer and AudioConverter are used as
well.
Simplex output: Simplex output uses a single callback. No ring buffer or
audio converter is used because AUHAL does its own output SR conversion.
Duplex, one device (no SR conversion): When one device is used, a single
callback is used. This achieves very low latency.
Duplex, separate devices or SR conversion: When SR conversion is
required, data must be buffered before it is converted and data is not
always available at the same times on input and output, so SR conversion
requires the same treatment as separate devices. The input callback
reads data and puts it in the ring buffer. The output callback reads the
data off the ring buffer, into an audio converter and finally to the
buffer processor.
Platform Specific Options:
By using the flags in pa_mac_core.h, the user may specify several options.
For example, the user can specify the sample-rate conversion quality, and
the extent to which PA will attempt to "play nice" and to what extent it
will interrupt other apps to improve performance. For example, if 44100 Hz
sample rate is requested but the device is set at 48000 Hz, PA can either
change the device for optimal playback ("Pro" mode), which may interrupt
other programs playing back audio, or simple use a sample-rate conversion,
which allows for friendlier sharing of the device ("Play Nice" mode).
Additionally, the user may define a "channel mapping" by calling
paSetupMacCoreChannelMap() on their stream info structure before opening
the stream with it. See below for creating a channel map.
Known issues:
- Buffering: No buffering beyond that provided by core audio is provided
except where absolutely needed for the implementation to work. This may cause
issues with large framesPerBuffer settings and it also means that no additional
latency will be provided even if a large latency setting is selected.
- Latency: Latency settings are generally ignored. They may be used as a
hint for buffer size in paHostFramesPerBufferUnspecified, or the value may
be used in cases where additional buffering is needed, such as doing input and
output on separate devices. Latency settings are always automatically bound
to "safe" values, however, so setting extreme values here should not be
an issue.
- Buffer Size: paHostFramesPerBufferUnspecified and specific host buffer sizes
are supported. paHostFramesPerBufferUnspecified works best in "pro" mode,
where the buffer size and sample rate of the audio device is most likely
to match the expected values. In the case of paHostFramesPerBuffer, an
appropriate framesPerBuffer value will be used that guarantees minimum
requested latency if that's possible.
- Timing info. It reports on stream time, but I'm probably doing something
wrong since patest_sine_time often reports negative latency numbers. Also,
there are currently issues with some devices whehn plugging/unplugging
devices.
- xrun detection: The only xrun detection performed is when reading
and writing the ring buffer. There is probably more that can be done.
- abort/stop issues: stopping a stream is always a complete operation,
but latency should be low enough to make the lack of a separate abort
unnecessary. Apple clarifies its AudioOutputUnitStop() call here:
http://lists.apple.com/archives/coreaudio-api/2005/Dec/msg00055.html
- blocking interface: should work fine.
- multichannel: It has been tested successfully on multichannel hardware
from MOTU: traveler and 896HD. Also Presonus firepod and others. It is
believed to work with all Core Audio devices, including virtual devices
such as soundflower.
- sample rate conversion quality: By default, SR conversion is the maximum
available. This can be tweaked using flags pa_mac_core.h. Note that the AU
render quyality property is used to set the sample rate conversion quality
as "documented" here:
http://lists.apple.com/archives/coreaudio-api/2004/Jan/msg00141.html
- x86/Universal Binary: Universal binaries can be build.
Creating a channel map:
How to create the map array - Text taken From AUHAL.rtfd :
[3] Channel Maps
Clients can tell the AUHAL units which channels of the device they are interested in. For example, the client may be processing stereo data, but outputting to a six-channel device. This is done by using the kAudioOutputUnitProperty_ChannelMap property. To use this property:
For Output:
Create an array of SInt32 that is the size of the number of channels of the device (Get the Format of the AUHAL's output Element == 0)
Initialize each of the array's values to -1 (-1 indicates that that channel is NOT to be presented in the conversion.)
Next, for each channel of your app's output, set:
channelMapArray[deviceOutputChannel] = desiredAppOutputChannel.
For example: we have a 6 channel output device and our application has a stereo source it wants to provide to the device. Suppose we want that stereo source to go to the 3rd and 4th channels of the device. The channel map would look like this: { -1, -1, 0, 1, -1, -1 }
Where the formats are:
Input Element == 0: 2 channels (- client format - settable)
Output Element == 0: 6 channels (- device format - NOT settable)
So channel 2 (zero-based) of the device will take the first channel of output and channel 3 will take the second channel of output. (This translates to the 3rd and 4th plugs of the 6 output plugs of the device of course!)
For Input:
Create an array of SInt32 that is the size of the number of channels of the format you require for input. Get (or Set in this case as needed) the AUHAL's output Element == 1.
Next, for each channel of input you require, set:
channelMapArray[desiredAppInputChannel] = deviceOutputChannel;
For example: we have a 6 channel input device from which we wish to receive stereo input from the 3rd and 4th channels. The channel map looks like this: { 2, 3 }
Where the formats are:
Input Element == 0: 2 channels (- device format - NOT settable)
Output Element == 0: 6 channels (- client format - settable)
----------------------------------------
Notes on Original implementation:
by Phil Burk and Darren Gibbs
Last updated March 20, 2002
WHAT WORKS
Output with very low latency, <10 msec.
Half duplex input or output.
Full duplex on the same CoreAudio device.
The paFLoat32, paInt16, paInt8, paUInt8 sample formats.
Pa_GetCPULoad()
Pa_StreamTime()
KNOWN BUGS OR LIMITATIONS
We do not yet support simultaneous input and output on different
devices. Note that some CoreAudio devices like the Roland UH30 look
like one device but are actually two different CoreAudio devices. The
Built-In audio is typically one CoreAudio device.
Mono doesn't work.
DEVICE MAPPING
CoreAudio devices can support both input and output. But the sample
rates supported may be different. So we have map one or two PortAudio
device to each CoreAudio device depending on whether it supports
input, output or both.
When we query devices, we first get a list of CoreAudio devices. Then
we scan the list and add a PortAudio device for each CoreAudio device
that supports input. Then we make a scan for output devices.
