-#   PA_PRIVATE_COMPILE_DEFINITIONS - This contains a list of preprocessor

-#       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

-#       relevant for Windows shared libraries which require a list of export
-#       symbols.

-# 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:
-
-    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;

- @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.

- @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.

-
-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;

-    the implementation.

-
-    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.
-
-    Andrew Baldwin: contributed fixes for compatibility problems with more
-    recent versions of the gcc assembler.

-// 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.

-// 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

-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.
