For digital audio output it is the time between making -a sound in software and finally hearing it. -<p>Consider the example of pressing a key on the ASCII keyboard to play -a note. There are several stages in this process which each contribute -their own latency. First the operating system must respond to the keypress. -Then the audio signal generated must work its way through the PortAudio -buffers. Then it must work its way through the audio card hardware. Then -it must go through the audio amplifier which is very quick and then travel -through the air. Sound travels at abous one foot per millisecond through -air so placing speakers across the room can add 5-20 msec of delay. -<p>The reverse process occurs when recording or responding to audio input. -If you are processing audio, for example if you implement a software guitar -fuzz box, then you have both the audio input and audio output latencies -added together. -<p>The audio buffers are used to prevent glitches in the audio stream. -The user software writes audio into the output buffers. That audio is read -by the low level audio driver or by DMA and sent to the DAC. If the computer -gets busy doing something like reading the disk or redrawing the screen, -then it may not have time to fill the audio buffer. The audio hardware -then runs out of audio data, which causes a glitch. By using a large enough -buffer we can ensure that there is always enough audio data for the audio -hardware to play. But if the buffer is too large then the latency is high -and the system feels sluggish. If you play notes on the keyboard then the -"instrument" will feel unresponsive. So you want the buffers to be as small -as possible without glitching. -<h2> -<a NAME="portaudio"></a>PortAudio and Latency</h2> -The only delay that PortAudio can control is the total length of its buffers. -The Pa_OpenStream() call takes two parameters: numBuffers and framesPerBuffer. -The latency is also affected by the sample rate which we will call framesPerSecond. -A frame is a set of samples that occur simultaneously. For a stereo stream, -a frame is two samples. -<p>The latency in milliseconds due to this buffering is: -<blockquote><tt>latency_msec = 1000 * numBuffers * framesPerBuffer / framesPerSecond</tt></blockquote> -This is not the total latency, as we have seen, but it is the part we can -control. -<p>If you call Pa_OpenStream() with numBuffers equal to zero, then PortAudio -will select a conservative number that will prevent audio glitches. If -you still get glitches, then you can pass a larger value for numBuffers -until the glitching stops. if you try to pass a numBuffers value that is -too small, then PortAudio will use its own idea of the minimum value. -<p>PortAudio decides on the minimum number of buffers in a conservative -way based on the frameRate, operating system and other variables. You can -query the value that PortAudio will use by calling: -<blockquote><tt>int Pa_GetMinNumBuffers( int framesPerBuffer, double sampleRate -);</tt></blockquote> -On some systems you can override the PortAudio minimum if you know your -system can handle a lower value. You do this by setting an environment -variable called PA_MIN_LATENCY_MSEC which is read by PortAudio when it -starts up. This is supported on the PortAudio implementations for Windows -MME, Windows DirectSound, and Unix OSS. -<h2> -<a NAME="macintosh"></a>Macintosh</h2> -The best thing you can do to improve latency on Mac OS 8 and 9 is to turn -off Virtual Memory. PortAudio V18 will detect that Virtual Memory is turned -off and use a very low latency. -<p>For Mac OS X the latency is very low because Apple Core Audio is so -well written. You can set the PA_MIN_LATENCY_MSEC variable using: -<blockquote><tt>setenv PA_MIN_LATENCY_MSEC 4</tt></blockquote> - -<h2> -<a NAME="unix"></a>Unix</h2> -PortAudio under Unix currently uses a backgroud thread that reads and writes -to OSS. This gives you decent but not great latency. But if you raise the -priority of the background thread to a very priority then you can get under -10 milliseconds latency. In order to raise your priority you must run the -PortAudio program as root! You must also set PA_MIN_LATENCY_MSEC using -the appropriate command for your shell. -<h2> -<a NAME="windows"></a>Windows</h2> -Latency under Windows is a complex issue because of all the alternative -operating system versions and device drivers. I have seen latency range -from 8 milliseconds to 400 milliseconds. The worst case is when using Windows -NT. Windows 98 is a little better, and Windows XP can be quite good if -properly tuned. -<p>The underlying audio API also makes a lot of difference. If the audio -device has its own DirectSound driver then DirectSound can often provide -better latency than WMME. But if a real DirectSound driver is not available -for your device then it is emulated using WMME and the latency can be very -high. That's where I saw the 400 millisecond latency. The ASIO implementation -is generally very good and will give the lowest latency if available. -<p>You can set the PA_MIN_LATENCY_MSEC variable to 50, for example, by -entering in MS-DOS: -<blockquote><tt>set PA_MIN_LATENCY_MSEC=50</tt></blockquote> -If you enter this in a DOS window then you must run the PortAudio program -from that same window for the variable to have an effect. You can add that -line to your C:\AUTOEXEC.BAT file and reboot if you want it to affect any -PortAudio based program. -<p>For Windows XP, you can set environment variables as follows: -<ol> -<li> -Select "Control Panel" from the "Start Menu".</li> - -<li> -Launch the "System" Control Panel</li> - -<li> -Click on the "Advanced" tab.</li> - -<li> -Click on the "Environment Variables" button.</li> - -<li> -Click "New" button under User Variables.</li> - -<li> -Enter PA_MIN_LATENCY_MSEC for the name and some optimistic number for the -value.</li> - -<li> -Click OK, OK, OK.</li> -</ol> - -<h3> -Improving Latency on Windows</h3> -There are several steps you can take to improve latency under windows. -<ol> -<li> -Avoid reading or writng to disk when doing audio.</li> - -<li> -Turn off all automated background tasks such as email clients, virus scanners, -backup programs, FTP servers, web servers, etc. when doing audio.</li> - -<li> -Disconnect from the network to prevent network traffic from interrupting -your CPU.</li> -</ol> -<b>Important: </b>Windows XP users can also tune the OS to favor background -tasks, such as audio, over foreground tasks, such as word processing.

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. -*/ - - -// We only need IASIOThiscallResolver at all if we are on Win32.

Implementing it is not necessary because -// it is not called by parts of the ASIO SDK which call through -// theAsioDriver ptr.

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 neccesary 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 accross 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 accross 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. -*/ - - -#include "portaudio.h" -#include "pa_converters.h" -#include "pa_dither.h" - -#ifdef __cplusplus -extern "C" -{ -#endif /* __cplusplus */ - - -/** @brief Mode flag passed to PaUtil_InitializeBufferProcessor indicating the type - of buffering that the host API uses. - - The mode used depends on whether the host API or the implementation manages - the buffers, and how these buffers are used (scatter gather, circular buffer). -*/ -typedef enum { -/** The host buffer size is a fixed known size. */ - paUtilFixedHostBufferSize, - -/** The host buffer size may vary, but has a known maximum size. */ - paUtilBoundedHostBufferSize, - -/** Nothing is known about the host buffer size. */ - paUtilUnknownHostBufferSize, - -/** The host buffer size varies, and the client does not require the buffer - processor to consume all of the input and fill all of the output buffer.

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.

(This - happens on my machine: make does not understand syntax with 2 colons on a line, - like this: - $(TESTS): bin/%: [snip] - - Maybe this is due to an old make version(?), my only solution is: use gmake. - Anyway, all the tests compile well now, with GCC 3.3, as well as with MIPSpro 7.2.1. - Tested: - - paqa_devs ok, but at a certain point digital i/o fails: - TestAdvance: INPUT, device = 2, rate = 32000, numChannels = 1, format = 1 - Possibly, this is an illegal sr or number of channels for digital i/o. - - paqa_errs 13 of the tests run ok, but 5 of them give weird results. - + patest1 ok. - + patest_buffer ok. - + patest_callbackstop ok. - - patest_clip ok, but hear no difference between dithering turned OFF and ON. - + patest_hang ok. - + patest_latency ok. - + patest_leftright ok. - + patest_maxsines ok. - + patest_many ok. - + patest_multi_sine ok. - + patest_pink ok. - + patest_prime ok. - - patest_read_record ok, but playback stops a little earlier than 5 seconds it seems(?). - + patest_record ok. - + patest_ringmix ok. - + patest_saw ok. - + patest_sine ok. - + patest_sine8 ok. - - patest_sine_formats ok, FLOAT32 + INT16 + INT18 are OK, but UINT8 IS NOT OK! - + patest_sine_time ok. - + patest_start_stop ok, but under/overflow errors of course in the AL queue monitor. - + patest_stop ok. - - patest_sync ok? - + patest_toomanysines ok. - - patest_underflow ok?

Very roughly implemented now, the adaption - to limited-requested latencies and samplerate may be improved. At least this - implementation chooses its own internal host buffer size (no coredumps any longer). - 005 OK: Blocking Read/Write Interface. - 006: Non-interleaved buffers seems OK? Covered by the buffer-processor and such?.... - 009 OK: Host error reporting should now be. - 010 OK: State Machine and State Querying Functions. - 011 OK: Renaming done. - 014 Implementation Style Guidelines (sorry, my braces are not ANSI style). - 015 OK: Callback Timestamps (During priming, though, these are still null!). - 016 OK: Use Structs for Pa_OpenStream() Parameters. - 019: Notify Client When All Buffers Have Played (Ok, covered by the buffer processor?) - 020 OK: Allow Callback to prime output stream (StartStream() should do the priming) - Should be tested more thoroughly for full duplex streams. (patest_prime seems ok). - - - @todo Underrun or overflow flags at some more places. - - @todo Callback Timestamps during priming. - - @todo Improve adaption to number of channels, samplerate and such when inventing - some frames per host buffer (when client requests 0). - - @todo Make a complete new version to support 'sproc'-applications. - Or could we manage that with some clever if-defs? - It must be clear which version we use (especially when using pa as lib!): - an irix-sproc() version or pthread version. - - @todo In Makefile.in: 'make clean' does not remove lib/libportaudio.so.0.0.19. - - Note: Even when mono-output is requested, with ALv7, the audio library opens - a outputs stereo.

It should be considered -an alpha release with zero guarantee not to crash on any particular -system. So far it has only been tested in the author's development -environment, which means a Win2k/SP2 PIII laptop with integrated -SoundMAX driver and USB Tascam US-428 compiled with both MinGW -(GCC 3.3) and MSVC++6 using the MS DirectX 9 SDK. -It has been most widely tested with the MinGW build, with most of the -test programs (particularly paqa_devs and paqa_errs) passing. -There are some notable failures: patest_out_underflow and both of the -blocking I/O tests (as blocking I/O is not implemented). -At this point the code needs to be tested with a much wider variety -of configurations and feedback provided from testers regarding -both working and failing cases. - -What is the WDM-KS host API? ----------------------------- -PortAudio for Windows currently has 3 functional host implementations. -MME uses the oldest Windows audio API which does not offer good -play/record latency. -DirectX improves this, but still imposes a penalty -of 10s of milliseconds due to the system mixing of streams from -multiple applications. -ASIO offers very good latency, but requires special drivers which are -not always available for cheaper audio hardware. Also, when ASIO -drivers are available, they are not always so robust because they -bypass all of the standardised Windows device driver architecture -and hit the hardware their own way. -Alternatively there are a couple of free (but closed source) ASIO -implementations which connect to the lower level Windows -"Kernel Streaming" API, but again these require special installation -by the user, and can be limited in functionality or difficult to use. - -This is where the PortAudio "WDM-KS" host implementation comes in. -It directly connects PortAudio to the same Kernel Streaming API which -those ASIO bridges use. This avoids the mixing penatly of DirectX, -giving at least as good latency as any ASIO driver, but it has the -advantage of working with ANY Windows audio hardware which is available -through the normal MME/DirectX routes without the user requiring -any additional device drivers to be installed, and allowing all -device selection to be done through the normal PortAudio API. - -Note that in general you should only be using this host API if your -application has a real requirement for very low latency audio (<20ms), -either because you are generating sounds in real-time based upon -user input, or you a processing recorded audio in real time. - -The only thing to be aware of is that using the KS interface will -block that device from being used by the rest of system through -the higher level APIs, or conversely, if the system is using -a device, the KS API will not be able to use it. MS recommend that -you should keep the device open only when your application has focus. -In PortAudio terms, this means having a stream Open on a WDMKS device. - -Usage ------ -To add the WDMKS backend to your program which is already using -PortAudio, you must undefine PA_NO_WDMKS from your build file, -and include the pa_win_wdmks\pa_win_wdmks.c into your build. -The file should compile in both C and C++. -You will need a DirectX SDK installed on your system for the -ks.h and ksmedia.h header files. -You will need to link to the system "setupapi" library. -Note that if you use MinGW, you will get more warnings from -the DX header files when using GCC(C), and still a few warnings -with G++(CPP). \ No newline at end of file diff --git a/src/audio/portaudio/pa_win_wmme/pa_win_wmme.c b/src/audio/portaudio/pa_win_wmme/pa_win_wmme.c deleted file mode 100644 index 86b6cdf143e3be3bee5ebd4a77afd62f4a42d3a9..0000000000000000000000000000000000000000 --- a/src/audio/portaudio/pa_win_wmme/pa_win_wmme.c +++ /dev/null @@ -1,3623 +0,0 @@ -/* - * $Id$ - * pa_win_wmme.c - * Implementation of PortAudio for Windows MultiMedia Extensions (WMME) - * - * PortAudio Portable Real-Time Audio Library - * Latest Version at: http://www.portaudio.com - * - * Authors: Ross Bencina and Phil Burk - * Copyright (c) 1999-2000 Ross Bencina and Phil Burk - * - * Permission is hereby granted, free of charge, to any person obtaining - * a copy of this software and associated documentation files - * (the "Software"), to deal in the Software without restriction, - * including without limitation the rights to use, copy, modify, merge, - * publish, distribute, sublicense, and/or sell copies of the Software, - * and to permit persons to whom the Software is furnished to do so, - * subject to the following conditions: - * - * The above copyright notice and this permission notice shall be - * included in all copies or substantial portions of the Software. - * - * Any person wishing to distribute modifications to the Software is - * requested to send the modifications to the original developer so that - * they can be incorporated into the canonical version. - * - * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, - * EXPRESS OR IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF - * MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT. - * IN NO EVENT SHALL THE AUTHORS OR COPYRIGHT HOLDERS BE LIABLE FOR - * ANY CLAIM, DAMAGES OR OTHER LIABILITY, WHETHER IN AN ACTION OF - * CONTRACT, TORT OR OTHERWISE, ARISING FROM, OUT OF OR IN CONNECTION - * WITH THE SOFTWARE OR THE USE OR OTHER DEALINGS IN THE SOFTWARE. - * - */ - -/* Modification History: - PLB = Phil Burk - JM = Julien Maillard - RDB = Ross Bencina - PLB20010402 - sDevicePtrs now allocates based on sizeof(pointer) - PLB20010413 - check for excessive numbers of channels - PLB20010422 - apply Mike Berry's changes for CodeWarrior on PC - including conditional inclusion of memory.h, - and explicit typecasting on memory allocation - PLB20010802 - use GlobalAlloc for sDevicesPtr instead of PaHost_AllocFastMemory - PLB20010816 - pass process instead of thread to SetPriorityClass() - PLB20010927 - use number of frames instead of real-time for CPULoad calculation. - JM20020118 - prevent hung thread when buffers underflow. - PLB20020321 - detect Win XP versus NT, 9x; fix DBUG typo; removed init of CurrentCount - RDB20020411 - various renaming cleanups, factored streamData alloc and cpu usage init - RDB20020417 - stopped counting WAVE_MAPPER when there were no real devices - refactoring, renaming and fixed a few edge case bugs - RDB20020531 - converted to V19 framework - ** NOTE maintanance history is now stored in CVS ** -*/ - -/** @file - - @todo Fix buffer catch up code, can sometimes get stuck (perhaps fixed now, - needs to be reviewed and tested.) - - @todo implement paInputUnderflow, paOutputOverflow streamCallback statusFlags, paNeverDropInput. - - @todo BUG: PA_MME_SET_LAST_WAVEIN/OUT_ERROR is used in functions which may - be called asynchronously from the callback thread. this is bad. - - @todo implement inputBufferAdcTime in callback thread - - @todo review/fix error recovery and cleanup in marked functions - - @todo implement timeInfo for stream priming - - @todo handle the case where the callback returns paAbort or paComplete during stream priming. - - @todo review input overflow and output underflow handling in ReadStream and WriteStream - -Non-critical stuff for the future: - - @todo Investigate supporting host buffer formats > 16 bits - - @todo define UNICODE and _UNICODE in the project settings and see what breaks - -*/ - -/* - How it works: - - For both callback and blocking read/write streams we open the MME devices - in CALLBACK_EVENT mode.
