(do not forget to activate fulltuplex with using the _TRIGGER_ stuff) (you need to frist deactivate audio and then start the trigger after the DAC is prefilled (see below)) This will give you a total input to output latency of 4x32 samples = 128 samples which at 44.1kHz correspond to 2.9msec latency. now set your process to SCHED_FIFO (see man sched_setscheduler) after the initialization your code should do more than less this: - write() 4 x 32 samples to the audio fd in order to prefill the DAC. Without this you will get dropouts. while(1) { read() 32 samples from ADC perform_dsp_stuff() on the 32 samples write() 32 samples to DAC } If you use a low latency kernel and pay attention to all the stuff above, then you will get rock solid 3msec latencies (plus eventual converter latencies but these are in the 1-2msec range AFAIK). Using multiple threads , pipes etc, only complicates your life and often makes it impossible to achieve these low latences. Realtime/audio programming is not an easy task , this is why people often fail to get the desired results even if their hardware is low-latency capable. The problem is that the final latency depends on the hardware you use, the application and the operating system. cheers, Benno. http://www.linuxaudiodev.org The Home of Linux Audio Development On Sat, 30 Jun 2001, you wrote: > On 2001-06-29 21:38 +0200, Benno Senoner wrote: > > > OSS/Free refuses to use a low # of frags ? > > > > That's a myth. > > I hope it is. :-) > > The fact is that ioctl(SNDCTL_DSP_SETFRAGMENT) succeeds with > values as low a 0x10007 (one 128-B fragment) but the latency is > still high enough to be clearly noticeable, which suggests that > it's *way* above 2/3 ms.

This fixed several problems with soundcards that did not take kindly to using 24-bit 3-byte formats. * OpenStream: Make the minimum framesPerHostIBuffer (and framesPerHostOBuffer) the default frameSize for the playback/recording pin. * ProcessingThread: Added a switch to only call PaUtil_EndBufferProcessing if the total input frames equals the total output frames 5th September 2004: This is the first public version of the code. 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 define PA_USE_WDMKS=1 in 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). portaudio/src/hostapi/wmme/0000755000076400007660000000000012272324571014760 5ustar philphilportaudio/src/hostapi/wmme/pa_win_wmme.c0000644000076400007660000045624112044141513017430 0ustar philphil/* * $Id: pa_win_wmme.c 1874 2012-10-31 06:20:59Z rbencina $ * 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. * * 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. */ /* * The text above constitutes the entire PortAudio license; however, * the PortAudio community also makes the following non-binding requests: * * 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.

In this mode, MME signals an Event object whenever it has finished with a buffer (either filled it for input, or played it for output). Where necessary, we block waiting for Event objects using WaitMultipleObjects(). When implementing a PA callback stream, we set up a high priority thread which waits on the MME buffer Events and drains/fills the buffers when they are ready. When implementing a PA blocking read/write stream, we simply wait on these Events (when necessary) inside the ReadStream() and WriteStream() functions. */ #include #include #include #include #include #ifndef UNDER_CE #include #endif #include /* PLB20010422 - "memory.h" doesn't work on CodeWarrior for PC.

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 coversion, 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 seperate 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. portaudio/src/hostapi/coreaudio/pa_mac_core_blocking.h0000644000076400007660000001104310755242111022226 0ustar philphil/* * Internal blocking interfaces for PortAudio Apple AUHAL implementation * * PortAudio Portable Real-Time Audio Library * Latest Version at: http://www.portaudio.com * * Written by Bjorn Roche of XO Audio LLC, from PA skeleton code. * Portions copied from code by Dominic Mazzoni (who wrote a HAL implementation) * * Dominic's code was based on code by Phil Burk, Darren Gibbs, * Gord Peters, Stephane Letz, and Greg Pfiel. * * The following people also deserve acknowledgements: * * Olivier Tristan for feedback and testing * Glenn Zelniker and Z-Systems engineering for sponsoring the Blocking I/O * interface. * * * Based on the Open Source API proposed by Ross Bencina * Copyright (c) 1999-2002 Ross Bencina, 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. * * 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. */ /* * The text above constitutes the entire PortAudio license; however, * the PortAudio community also makes the following non-binding requests: * * 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.

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 // // Note that this #include must come after the other ASIO SDK // #includes, for example: // // #include // #include // #include // #include // #include // // Actually the important thing is to #include // after . 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 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 // 1.0 Initial working version. // Created: 6/09/2003 // Authors: Fraser Adams // Ross Bencina // Rene G.

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;

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 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.

Overview

This is a PortAudio implementation for the AudioScience HPI Audio API on the Linux platform. AudioScience makes a range of audio adapters customised for the broadcasting industry, with support for both Windows and Linux. More information on their products can be found on their website: http://www.audioscience.com Documentation for the HPI API can be found at: http://www.audioscience.com/internet/download/sdk/hpi_usermanual_html/html/index.html The Linux HPI driver itself (a kernel module + library) can be downloaded from: http://www.audioscience.com/internet/download/linux_drivers.htm

Implementation strategy

*Note* Ideally, AudioScience cards should be handled by the PortAudio ALSA implementation on Linux, as ALSA is the preferred Linux soundcard API. The existence of this host API implementation might therefore seem a bit flawed. Unfortunately, at the time of the creation of this implementation (June 2006), the PA ALSA implementation could not make use of the existing AudioScience ALSA driver. PA ALSA uses the "memory-mapped" (mmap) ALSA access mode to interact with the ALSA library, while the AudioScience ALSA driver only supports the "read-write" access mode. The appropriate solution to this problem is to add "read-write" support to PortAudio ALSA, thereby extending the range of soundcards it supports (AudioScience cards are not the only ones with this problem). Given the author's limited knowledge of ALSA and the simplicity of the HPI API, the second-best solution was born... The following mapping between HPI and PA was followed: HPI subsystem => PortAudio host API HPI adapter => nothing specific HPI stream => PortAudio device Each HPI stream is either input or output (not both), and can support different channel counts, sampling rates and sample formats. It is therefore a more natural fit to a PA device. A PA stream can therefore combine two HPI streams (one input and one output) into a "full-duplex" stream. These HPI streams can even be on different physical adapters. The two streams ought to be sample-synchronised when they reside on the same adapter, as most AudioScience adapters derive their ADC and DAC clocks from one master clock. When combining two adapters into one full-duplex stream, however, the use of a word clock connection between the adapters is strongly recommended. The HPI interface is inherently blocking, making use of read and write calls to transfer data between user buffers and driver buffers. The callback interface therefore requires a helper thread ("callback engine") which periodically transfers data (one thread per PA stream, in fact). The current implementation explicitly sleeps via Pa_Sleep() until enough samples can be transferred (select() or poll() would be better, but currently seems impossible...). The thread implementation makes use of the Unix thread helper functions and some pthread calls here and there. If a unified PA thread exists, this host API implementation might also compile on Windows, as this is the only real Linux-specific part of the code. There is no inherent fixed buffer size in the HPI interface, as in some other host APIs. The PortAudio implementation contains a buffer that is allocated during OpenStream and used to transfer data between the callback and the HPI driver buffer. The size of this buffer is quite flexible and is derived from latency suggestions and matched to the requested callback buffer size as far as possible. It can become quite huge, as the AudioScience cards are typically geared towards higher-latency applications and contain large hardware buffers. The HPI interface natively supports most common sample formats and sample rates (some conversion is done on the adapter itself). Stream time is measured based on the number of processed frames, which is adjusted by the number of frames currently buffered by the HPI driver. There is basic support for detecting overflow and underflow. The HPI interface does not explicitly indicate this, so thresholds on buffer levels are used in combination with stream state. Recovery from overflow and underflow is left to the PA client. Blocking streams are also implemented. It makes use of the same polling routines that the callback interface uses, in order to prevent the allocation of variable-sized buffers during reading and writing. The framesPerBuffer parameter is therefore still relevant, and this can be increased in the blocking case to improve efficiency. The implementation contains extensive reporting macros (slightly modified PA_ENSURE and PA_UNLESS versions) and a useful stream dump routine to provide debugging feedback. Output buffer priming via the user callback (i.e. paPrimeOutputBuffersUsingStreamCallback and friends) is not implemented yet. All output is primed with silence. */ #include #include #include #include /* strlen() */ #include /* pthreads and friends */ #include /* assert */ #include /* ceil, floor */ #include /* HPI API */ #include "portaudio.h" /* PortAudio API */ #include "pa_util.h" /* PA_DEBUG, other small utilities */ #include "pa_unix_util.h" /* Unix threading utilities */ #include "pa_allocation.h" /* Group memory allocation */ #include "pa_hostapi.h" /* Host API structs */ #include "pa_stream.h" /* Stream interface structs */ #include "pa_cpuload.h" /* CPU load measurer */ #include "pa_process.h" /* Buffer processor */ #include "pa_converters.h" /* PaUtilZeroer */ #include "pa_debugprint.h" /* -------------------------------------------------------------------------- */ /* * Defines */ /* Error reporting and assertions */ /** Evaluate expression, and return on any PortAudio errors */ #define PA_ENSURE_(expr) \ do { \ PaError paError = (expr); \ if( UNLIKELY( paError < paNoError ) ) \ { \ PA_DEBUG(( "Expression '" #expr "' failed in '" __FILE__ "', line: " STRINGIZE( __LINE__ ) "\n" )); \ result = paError; \ goto error; \ } \ } while (0); /** Assert expression, else return the provided PaError */ #define PA_UNLESS_(expr, paError) \ do { \ if( UNLIKELY( (expr) == 0 ) ) \ { \ PA_DEBUG(( "Expression '" #expr "' failed in '" __FILE__ "', line: " STRINGIZE( __LINE__ ) "\n" )); \ result = (paError); \ goto error; \ } \ } while( 0 ); /** Check return value of HPI function, and map it to PaError */ #define PA_ASIHPI_UNLESS_(expr, paError) \ do { \ hpi_err_t hpiError = (expr); \ /* If HPI error occurred */ \ if( UNLIKELY( hpiError ) ) \ { \ char szError[256]; \ HPI_GetErrorText( hpiError, szError ); \ PA_DEBUG(( "HPI error %d occurred: %s\n", hpiError, szError )); \ /* This message will always be displayed, even if debug info is disabled */ \ PA_DEBUG(( "Expression '" #expr "' failed in '" __FILE__ "', line: " STRINGIZE( __LINE__ ) "\n" )); \ if( (paError) == paUnanticipatedHostError ) \ { \ PA_DEBUG(( "Host error description: %s\n", szError )); \ /* PaUtil_SetLastHostErrorInfo should only be used in the main thread */ \ if( pthread_equal( pthread_self(), paUnixMainThread ) ) \ { \ PaUtil_SetLastHostErrorInfo( paInDevelopment, hpiError, szError ); \ } \ } \ /* If paNoError is specified, continue as usual */ \ /* (useful if you only want to print out the debug messages above) */ \ if( (paError) < 0 ) \ { \ result = (paError); \ goto error; \ } \ } \ } while( 0 ); /** Report HPI error code and text */ #define PA_ASIHPI_REPORT_ERROR_(hpiErrorCode) \ do { \ char szError[256]; \ HPI_GetErrorText( hpiError, szError ); \ PA_DEBUG(( "HPI error %d occurred: %s\n", hpiError, szError )); \ /* PaUtil_SetLastHostErrorInfo should only be used in the main thread */ \ if( pthread_equal( pthread_self(), paUnixMainThread ) ) \ { \ PaUtil_SetLastHostErrorInfo( paInDevelopment, (hpiErrorCode), szError ); \ } \ } while( 0 ); /* Defaults */ /** Sample formats available natively on AudioScience hardware */ #define PA_ASIHPI_AVAILABLE_FORMATS_ (paFloat32 | paInt32 | paInt24 | paInt16 | paUInt8) /** Enable background bus mastering (BBM) for buffer transfers, if available (see HPI docs) */ #define PA_ASIHPI_USE_BBM_ 1 /** Minimum number of frames in HPI buffer (for either data or available space).

Overview

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.

Initialization, resetting and termination

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.

Using the buffer processor for a callback stream

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.

Using the buffer processor for a blocking read/write stream

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 copy 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 copy 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.

This function is also designed to be used with the proposed Pa_IsFormatSupported() function. There are basically two types of validation that could be performed: Generic conformance validation, and device capability mismatch validation. This function performs only generic conformance validation. Validation that would require knowledge of device capabilities is not performed because of potentially complex relationships between combinations of parameters - for example, even if the sampleRate seems ok, it might not be for a duplex stream - we have no way of checking this in an API-neutral way, so we don't try. On success the function returns PaNoError and fills in hostApi, hostApiInputDeviceID, and hostApiOutputDeviceID fields. On failure the function returns an error code indicating the first encountered parameter error. If ValidateOpenStreamParameters() returns paNoError, the following assertions are guaranteed to be true. - at least one of inputParameters & outputParmeters is valid (not NULL) - if inputParameters & outputParameters are both valid, that inputParameters->device & outputParameters->device both use the same host api PaDeviceIndex inputParameters->device - is within range (0 to Pa_GetDeviceCount-1) Or: - is paUseHostApiSpecificDeviceSpecification and inputParameters->hostApiSpecificStreamInfo is non-NULL and refers to a valid host api int inputParameters->channelCount - if inputParameters->device is not paUseHostApiSpecificDeviceSpecification, channelCount is > 0 - upper bound is NOT validated against device capabilities PaSampleFormat inputParameters->sampleFormat - is one of the sample formats defined in portaudio.h void *inputParameters->hostApiSpecificStreamInfo - if supplied its hostApi field matches the input device's host Api PaDeviceIndex outputParmeters->device - is within range (0 to Pa_GetDeviceCount-1) int outputParmeters->channelCount - if inputDevice is valid, channelCount is > 0 - upper bound is NOT validated against device capabilities PaSampleFormat outputParmeters->sampleFormat - is one of the sample formats defined in portaudio.h void *outputParmeters->hostApiSpecificStreamInfo - if supplied its hostApi field matches the output device's host Api double sampleRate - is not an 'absurd' rate (less than 1000. or greater than 384000.) - sampleRate is NOT validated against device capabilities PaStreamFlags streamFlags - unused platform neutral flags are zero - paNeverDropInput is only used for full-duplex callback streams with variable buffer size (paFramesPerBufferUnspecified) */ static PaError ValidateOpenStreamParameters( const PaStreamParameters *inputParameters, const PaStreamParameters *outputParameters, double sampleRate, unsigned long framesPerBuffer, PaStreamFlags streamFlags, PaStreamCallback *streamCallback, PaUtilHostApiRepresentation **hostApi, PaDeviceIndex *hostApiInputDevice, PaDeviceIndex *hostApiOutputDevice ) { int inputHostApiIndex = -1, /* Surpress uninitialised var warnings: compiler does */ outputHostApiIndex = -1;

Arrange for either the PA_LITTLE_ENDIAN or PA_BIG_ENDIAN preprocessor symbols to be defined. The one that is defined reflects the endianness of the target platform and may be used to implement conditional compilation of byte-order dependent code.

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.

The building of JPortAudio will eventually be integrated into the Makefile as an optional build. Currently JPortAudio is only supported for Windows and Macintosh. Please contact us if you want to help with porting Linux. For reference documentation of the JPortAudio API see: com.portaudio.PortAudio For an example see: PlaySine.java @section java_comp_windows Building JPortAudio on Windows Build the Java code using the Eclipse project in "jportaudio". Export as "jportaudio.jar". If you modify the JNI API then you will need to regenerate the JNI .h files using: @code cd bindings/java/scripts make_header.bat @endcode Build the JNI DLL using the Visual Studio 2010 solution in "java/c/build/vs2010/PortAudioJNI". @section java_use_windows Using JPortAudio on Windows Put the "jportaudio.jar" in the classpath for your application. Place the following libraries where they can be found, typically in the same folder as your application. - portaudio_x86.dll - portaudio_x64.dll - jportaudio_x86.dll - jportaudio_x64.dll @section java_comp_max Building JPortAudio on Mac These are notes from building JPortAudio on a Mac with 10.6.8 and XCode 4. I created a target of type 'C' library. I added the regular PortAudio frameworks plus the JavaVM framework. I modified com_portaudio_PortAudio.h and com_portaudio_BlockingStream.h so that jni.h could found. @code #if defined(__APPLE__) #include #else #include #endif @endcode This is bad because those header files are autogenerated and will be overwritten. We need a better solution for this. I had trouble finding the "libjportaudio.jnilib". So I added a Build Phase that copied the library to "/Users/phil/Library/Java/Extensions". On the Mac we can create a universal library for both 32 and 64-bit JVMs. So in the JAR file I will open "jportaudio" on Apple. ON WIndows I will continue to open "jportaudio_x64" and "jportaudio_x86". */ portaudio/bindings/cpp/0000755000076400007660000000000012272324571014134 5ustar philphilportaudio/bindings/cpp/portaudiocpp.pc.in0000644000076400007660000000036110444545326017600 0ustar philphilprefix=@prefix@ exec_prefix=@exec_prefix@ libdir=@libdir@ includedir=@includedir@ Name: PortAudioCpp Description: Portable audio I/O C++ bindings Version: 12 Requires: portaudio-2.0 Libs: -L${libdir} -lportaudiocpp Cflags: -I${includedir} portaudio/bindings/cpp/configure0000755000076400007660000205171311657014371016054 0ustar philphil#! /bin/sh # Guess values for system-dependent variables and create Makefiles. # Generated by GNU Autoconf 2.68 for PortAudioCpp 12. # # # Copyright (C) 1992, 1993, 1994, 1995, 1996, 1998, 1999, 2000, 2001, # 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010 Free Software # Foundation, Inc. # # # This configure script is free software; the Free Software Foundation # gives unlimited permission to copy, distribute and modify it. ## -------------------- ## ## M4sh Initialization. ## ## -------------------- ## # Be more Bourne compatible DUALCASE=1; export DUALCASE # for MKS sh if test -n "${ZSH_VERSION+set}" && (emulate sh) >/dev/null 2>&1; then : emulate sh NULLCMD=: # Pre-4.2 versions of Zsh do word splitting on ${1+"$@"}, which # is contrary to our usage.

Configuration: -h, --help display this help and exit --help=short display options specific to this package --help=recursive display the short help of all the included packages -V, --version display version information and exit -q, --quiet, --silent do not print \`checking ...' messages --cache-file=FILE cache test results in FILE [disabled] -C, --config-cache alias for \`--cache-file=config.cache' -n, --no-create do not create output files --srcdir=DIR find the sources in DIR [configure dir or \`..'] Installation directories: --prefix=PREFIX install architecture-independent files in PREFIX [$ac_default_prefix] --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX [PREFIX] By default, \`make install' will install all the files in \`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify an installation prefix other than \`$ac_default_prefix' using \`--prefix', for instance \`--prefix=\$HOME'. For better control, use the options below.

PortAudio

///

/// PortAudio is a portable and mature C API for accessing audio hardware. It offers both callback-based and blocking /// style input and output, deals with sample data format conversions, dithering and much more. There are a large number /// of implementations available for various platforms including Windows MME, Windows DirectX, Windows and MacOS (Classic) /// ASIO, MacOS Classic SoundManager, MacOS X CoreAudio, OSS (Linux), Linux ALSA, JACK (MacOS X and Linux) and SGI Irix /// AL. Note that, currently not all of these implementations are equally complete or up-to-date (as PortAudio V19 is /// still in development). Because PortAudio has a C API, it can easily be called from a variety of other programming /// languages. ///

///

PortAudioCpp

///

/// Although, it is possible to use PortAudio's C API from within a C++ program, this is usually a little awkward /// as procedural and object-oriented paradigms need to be mixed. PortAudioCpp aims to resolve this by encapsulating /// PortAudio's C API to form an equivalent object-oriented C++ API. It provides a more natural integration of PortAudio /// into C++ programs as well as a more structured interface. PortAudio's concepts were preserved as much as possible and /// no additional features were added except for some `convenience methods'. ///

///

/// PortAudioCpp's main features are: ///

    ///
  • Structured object model.
    • ///
  • C++ exception handling instead of C-style error return codes.
    • ///
  • Handling of callbacks using free functions (C and C++), static functions, member functions or instances of classes /// derived from a given interface.
    • ///
  • STL compliant iterators to host APIs and devices.
    • ///
  • Some additional convenience functions to more easily set up and use PortAudio.
    • ///
///

///

/// PortAudioCpp requires a recent version of the PortAudio V19 source code. This can be obtained from CVS or as a snapshot /// from the website. The examples also require the ASIO 2 SDK which can be obtained from the Steinberg website. Alternatively, the /// examples can easily be modified to compile without needing ASIO. ///

///

/// Supported platforms: ///

    ///
  • Microsoft Visual C++ 6.0, 7.0 (.NET 2002) and 7.1 (.NET 2003).
    • ///
  • GNU G++ 2.95 and G++ 3.3.
    • ///
/// Other platforms should be easily supported as PortAudioCpp is platform-independent and (reasonably) C++ standard compliant. ///

///

/// This documentation mainly provides information specific to PortAudioCpp. For a more complete explaination of all of the /// concepts used, please consult the PortAudio documentation. ///

///

/// PortAudioCpp was developed by Merlijn Blaauw with many great suggestions and help from Ross Bencina. Ludwig Schwardt provided /// GNU/Linux build files and checked G++ compatibility. PortAudioCpp may be used under the same licensing, conditions and /// warranty as PortAudio. See the PortAudio license for more details. ///

Perhaps it's better to just note mayor changes by date from now on. PortAudioCpp v19 revision 16 06/05/22: mblaauw: - Added up-to-date MSVC 6.0 projects created by David Moore. Besides MSVC 6.0 users, MSVC 7.0 users may use these projects and automatically convert them to MSVC 7.0 projects. - Changed the code and projects (MSVC 7.1 only) to be up-to-date with PortAudio's new directory structure. - Added equivalents of the PaAsio_GetInputChannelName() and PaAsio_GetOutputChannelName() functions to the AsioDeviceAdapter wrapper-class (missing functions pointed out by David Moore). - Added code to PortAudio's main SVN repository. PortAudioCpp v19 revision 15 (unknown release date): mblaauw: - Changed some exception handling code in HostApi's constructor. - Added accessors to PortAudio PaStream from PortAudioCpp Stream (their absense being pointed out by Tom Jordan). - Fixed a bug/typo in MemFunToCallbackInterfaceAdapter::init() thanks to Fredrik Viklund. - Fixed issue with concrete Stream classes possibly throwing an exception and fixed documentation w.r.t. this. - Moved files to portaudio/binding/cpp/. Made new msvc 7.1 projects to reflect the change and removed msvc 6.0 and 7.0 projects (because I can no longer maintain them myself). Gnu projects will probably need updating. PortAudioCpp v19 revision 14 03/10/24: mblaauw: - Fixed some error handling bugs in Stream and System (pointed out by Tom Jordan). - Updated documentation a little (main page). - Fixed order of members so initializer list was in the right order in StreamParameters (pointed out by Ludwig Schwardt). - Added new lines at EOF's (as indicated by Ludwig Schwardt). PortAudioCpp v19 revision 13 03/10/19: lschwardt: - Added build files for GNU/Linux. - Fixed bug in Exception where the inherited what() member function (and destructor) had looser exception specification (namely no exception specification, i.e. could throw anything) than the std::exception base class's what() member function (which had throw(), i.e. no-throw guarantee). - Changed the iterators so that they have a set of public typedefs instead of deriving the C++ standard library std::iterator<> struct. G++ 2.95 doesn't support std::exception<> and composition-by-aggregation is prefered over composition-by-inheritance in this case. - Changed some minor things to avoid G++ warning messages. mblaauw: - Renamed this file (/WHATSNEW.txt) to /CHANGELOG. - Renamed /PA_ISSUES.txt to /PA_ISSUES. - Added /INSTALL file with some build info for GNU/Linux and VC6. - Added MSVC 6.0 projects for building PortAudioCpp as a staticly or dynamically linkable library. - Moved build files to /build/(gnu/ or vc6/). - Moved Doxygen configuration files to /doc/ and output to /doc/api_reference/. - Added a /doc/README with some info how to generate Doxygen documentation. PortAudioCpp v19 revision 12 03/09/02: mblaauw: - Updated code to reflect changes on V19-devel CVS branch. - Fixed some typos in the documentation. PortAudioCpp v19 revision 11 03/07/31: mblaauw: - Renamed SingleDirecionStreamParameters to DirectionSpecificStreamParameters. - Implemented BlockingStream. - Updated code to reflect recent changes to PortAudio V19-devel. - Fixed a potential memory leak when an exception was thrown in the HostApi constructor. - Renamed ``Latency'' to ``BufferSize'' in AsioDeviceAdapter. - Updated class documentation. PortAudioCpp v19 revision 10 03/07/18: mblaauw: - SingleDirectionStreamParameters now has a (static) null() method. - StreamParameters uses references for the direction-specific stream parameters instead of pointers (use null() method (above) instead of NULL). - StreamParameters and SingleDirectionStreamParameters must now be fully specified and now default values are used (because this was not very useful in general and only made things more complex). - Updated documentation. PortAudioCpp v19 revision 09 03/06/25: mblaauw: - Changed some things in SingleDirectionStreamParameters to ease it's usage. - Placed all SingleDirectionStreamParameters stuff into a separate file. + Totally redid the callback stuff, now it's less ackward and supports C++ functions. PortAudioCpp v19 revision 08 03/06/20: mblaauw: - Made deconstructors for Device and HostApi private. + Added a AsioDeviceWrapper host api specific device extension class. - Refactored Exception into a Exception base class and PaException and PaCppException derived classes. - Added ASIO specific device info to the devs.cxx example. - Fixed a bug in System::hostApiCount() and System::defaultHostApi(). + Moved Device::null to System::nullDevice. - Fixed some bugs in Device and System. PortAudioCpp v19 revision 07 03/06/08: mblaauw: - Updated some doxy comments. + Renamed CbXyz to CallbackXyz. + Renamed all ``configurations'' to ``parameters''. + Renamed HalfDuplexStreamConfiguration to SingleDirectionStreamConfiguration. - Renamed SingleDirectionStreamParameters::streamParameters() to SingleDirectionStreamParameters::paSteamParameters. - Added a non-constant version of SingleDirectionStreamParameters::paStreamParameters(). - A few improvements to SingleDirectionStreamParameters. - Allowed AutoSystem to be created without initializing the System singleton (using a ctor flag). - Added a BlockingStream class (not implemented for now). - Fixed many bugs in the implementation of the iterators. - Fixed a bug in Device::operator==(). + Added a C++ version of the patest_sine.c test/example. - Added a ctor for StreamParameters for a default half-duplex stream. - Added SingleDirectionStreamParameters::setDevice() and setNumChannels(). - Renamed System::numHostApis() to System::hostApiCount(). + Rewrote the iterators and related classes. They are now fully STL compliant. The System now has a static array of all HostApis and all Devices. Only the System can create HostApis and Devices and they are non-copyable now. All HostApis and Devices are now passed by-reference. - Renamed (System::) getVersion() to version() and getVersionText() to versionText(). - Renamed (Device::) numXyzChannels() to maxXyzChannels(). - Changed some stuff in StreamParameters. + Added a C++ version of the patest_devs.c test/example. PortAudioCpp v19 revision 06 03/06/04: mblaauw: + Added this file to the project (roughly, a `+' denotes a major change, a `-' a minor change). - Added System::deviceByIndex(), useful when a Device's index is stored for instance. - Renamed System::hostApiFromTypeId() to System::hostApiByTypeId(). - Updated and added some Doxygen documentation. - Made Stream::usedIntputLatency(), Stream::usedOutputLatency() and Stream::usedSampleRate() throw an paInternalError equivalent exception instead of paBadStreamPtr. - Changed exception handling in Stream::open() functions. They now follow the PA error handling mechanism better and a couple of bugs regarding ownership of objects were fixed. - Renamed Device::isDefaultXyzDevice() to Device::isSystemDefaultXyzDevice(). - Added Device::isHostApiDefaultXyzDevice(). - Added StreamConfiguration::unsetFlag(). - Removed CUSTOM from SampleDataFormat. - System::hostApiByTypeId() now throws an paInternalError if the type id was out-of-range; this is a temporary work-around (see comments). - Changed CbInterface to use paCallbackFun() instead of operator()(). - Renamed ``object'' to ``instance'' in CbMemFunAdapter.hxx. - Added StreamConfiguration::setXyzHostApiSpecificSampleFormat(). - Added StreamConfiguration::isXyzSampleFormatHostApiSpecific(). - Changed error handling in System::terminate(), it can now throw an Exception. - Added error handling in System::defaultHostApi(). - Added error handling in System::hostApisEnd(). - Changed some (but probably not all) C casts to C++ casts to avoid confusion with a certain Python person. - Renamed RaiiSystem to AutoSystem (class and file) as this is a come common convention. - Renamed System::numDevices() to System::deviceCount() to be more compatible with PortAudio (although PortAudio uses Pa_CountDevices() instead, see comment). - Renamed HostApi::numDevices() to HostApi::deviceCount(). - Changed INC_ to INCLUDED_ in the header multiple include guards. - Changed the order of functions in the StreamConfiguration class' header. - Written some more info in PortAudioCpp.hxx (Doxygen). - Added CallbackStream.hxx and CallbackStream.cxx files. + Refactored StreamConfiguration to remove the duplication which was there. There is now a HalfDuplexStreamConfiguration class. Also made some improvements to these classes while doing the refactoring. + Moved all code files to source/portaudiocpp/ and changed includes. + Moved all header files to include/portaudiocpp/ to easy a binary build if needed. The project must be set to have .../include/ as a path to look for includes. + Refactored the Stream class into a Stream base class and a CallbackStream derived class. - Renamed Stream::usingXyz() to Stream::xyz(). - Updated some doxy comments. - Changed ``using namespace portaudio'' in .cxx files to ``namespace portaudio { ... }''.

This file is offered as-is, without warranty of any kind. Basic Installation ================== Briefly, the shell commands `./configure; make; make install' should configure, build, and install this package. The following more-detailed instructions are generic; see the `README' file for instructions specific to this package. Some packages provide this `INSTALL' file but do not implement all of the features documented below. The lack of an optional feature in a given package is not necessarily a bug. More recommendations for GNU packages can be found in *note Makefile Conventions: (standards)Makefile Conventions. The `configure' shell script attempts to guess correct values for various system-dependent variables used during compilation. It uses those values to create a `Makefile' in each directory of the package. It may also create one or more `.h' files containing system-dependent definitions. Finally, it creates a shell script `config.status' that you can run in the future to recreate the current configuration, and a file `config.log' containing compiler output (useful mainly for debugging `configure'). It can also use an optional file (typically called `config.cache' and enabled with `--cache-file=config.cache' or simply `-C') that saves the results of its tests to speed up reconfiguring. Caching is disabled by default to prevent problems with accidental use of stale cache files. If you need to do unusual things to compile the package, please try to figure out how `configure' could check whether to do them, and mail diffs or instructions to the address given in the `README' so they can be considered for the next release. If you are using the cache, and at some point `config.cache' contains results you don't want to keep, you may remove or edit it. The file `configure.ac' (or `configure.in') is used to create `configure' by a program called `autoconf'. You need `configure.ac' if you want to change it or regenerate `configure' using a newer version of `autoconf'. The simplest way to compile this package is: 1. `cd' to the directory containing the package's source code and type `./configure' to configure the package for your system. Running `configure' might take a while. While running, it prints some messages telling which features it is checking for. 2. Type `make' to compile the package. 3. Optionally, type `make check' to run any self-tests that come with the package, generally using the just-built uninstalled binaries. 4. Type `make install' to install the programs and any data files and documentation. When installing into a prefix owned by root, it is recommended that the package be configured and built as a regular user, and only the `make install' phase executed with root privileges. 5. Optionally, type `make installcheck' to repeat any self-tests, but this time using the binaries in their final installed location. This target does not install anything. Running this target as a regular user, particularly if the prior `make install' required root privileges, verifies that the installation completed correctly. 6. You can remove the program binaries and object files from the source code directory by typing `make clean'. To also remove the files that `configure' created (so you can compile the package for a different kind of computer), type `make distclean'. There is also a `make maintainer-clean' target, but that is intended mainly for the package's developers. If you use it, you may have to get all sorts of other programs in order to regenerate files that came with the distribution. 7. Often, you can also type `make uninstall' to remove the installed files again. In practice, not all packages have tested that uninstallation works correctly, even though it is required by the GNU Coding Standards. 8. Some packages, particularly those that use Automake, provide `make distcheck', which can by used by developers to test that all other targets like `make install' and `make uninstall' work correctly. This target is generally not run by end users. Compilers and Options ===================== Some systems require unusual options for compilation or linking that the `configure' script does not know about. Run `./configure --help' for details on some of the pertinent environment variables. You can give `configure' initial values for configuration parameters by setting variables in the command line or in the environment. Here is an example: ./configure CC=c99 CFLAGS=-g LIBS=-lposix *Note Defining Variables::, for more details. Compiling For Multiple Architectures ==================================== You can compile the package for more than one kind of computer at the same time, by placing the object files for each architecture in their own directory. To do this, you can use GNU `make'. `cd' to the directory where you want the object files and executables to go and run the `configure' script. `configure' automatically checks for the source code in the directory that `configure' is in and in `..'. This is known as a "VPATH" build. With a non-GNU `make', it is safer to compile the package for one architecture at a time in the source code directory. After you have installed the package for one architecture, use `make distclean' before reconfiguring for another architecture. On MacOS X 10.5 and later systems, you can create libraries and executables that work on multiple system types--known as "fat" or "universal" binaries--by specifying multiple `-arch' options to the compiler but only a single `-arch' option to the preprocessor. Like this: ./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \ CPP="gcc -E" CXXCPP="g++ -E" This is not guaranteed to produce working output in all cases, you may have to build one architecture at a time and combine the results using the `lipo' tool if you have problems. Installation Names ================== By default, `make install' installs the package's commands under `/usr/local/bin', include files under `/usr/local/include', etc. You can specify an installation prefix other than `/usr/local' by giving `configure' the option `--prefix=PREFIX', where PREFIX must be an absolute file name. You can specify separate installation prefixes for architecture-specific files and architecture-independent files. If you pass the option `--exec-prefix=PREFIX' to `configure', the package uses PREFIX as the prefix for installing programs and libraries. Documentation and other data files still use the regular prefix. In addition, if you use an unusual directory layout you can give options like `--bindir=DIR' to specify different values for particular kinds of files. Run `configure --help' for a list of the directories you can set and what kinds of files go in them. In general, the default for these options is expressed in terms of `${prefix}', so that specifying just `--prefix' will affect all of the other directory specifications that were not explicitly provided. The most portable way to affect installation locations is to pass the correct locations to `configure'; however, many packages provide one or both of the following shortcuts of passing variable assignments to the `make install' command line to change installation locations without having to reconfigure or recompile. The first method involves providing an override variable for each affected directory. For example, `make install prefix=/alternate/directory' will choose an alternate location for all directory configuration variables that were expressed in terms of `${prefix}'. Any directories that were specified during `configure', but not in terms of `${prefix}', must each be overridden at install time for the entire installation to be relocated. The approach of makefile variable overrides for each directory variable is required by the GNU Coding Standards, and ideally causes no recompilation. However, some platforms have known limitations with the semantics of shared libraries that end up requiring recompilation when using this method, particularly noticeable in packages that use GNU Libtool. The second method involves providing the `DESTDIR' variable. For example, `make install DESTDIR=/alternate/directory' will prepend `/alternate/directory' before all installation names. The approach of `DESTDIR' overrides is not required by the GNU Coding Standards, and does not work on platforms that have drive letters. On the other hand, it does better at avoiding recompilation issues, and works well even when some directory options were not specified in terms of `${prefix}' at `configure' time. Optional Features ================= If the package supports it, you can cause programs to be installed with an extra prefix or suffix on their names by giving `configure' the option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'. Some packages pay attention to `--enable-FEATURE' options to `configure', where FEATURE indicates an optional part of the package. They may also pay attention to `--with-PACKAGE' options, where PACKAGE is something like `gnu-as' or `x' (for the X Window System). The `README' should mention any `--enable-' and `--with-' options that the package recognizes. For packages that use the X Window System, `configure' can usually find the X include and library files automatically, but if it doesn't, you can use the `configure' options `--x-includes=DIR' and `--x-libraries=DIR' to specify their locations. Some packages offer the ability to configure how verbose the execution of `make' will be. For these packages, running `./configure --enable-silent-rules' sets the default to minimal output, which can be overridden with `make V=1'; while running `./configure --disable-silent-rules' sets the default to verbose, which can be overridden with `make V=0'. Particular systems ================== On HP-UX, the default C compiler is not ANSI C compatible. If GNU CC is not installed, it is recommended to use the following options in order to use an ANSI C compiler: ./configure CC="cc -Ae -D_XOPEN_SOURCE=500" and if that doesn't work, install pre-built binaries of GCC for HP-UX. On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot parse its `' header file. The option `-nodtk' can be used as a workaround. If GNU CC is not installed, it is therefore recommended to try ./configure CC="cc" and if that doesn't work, try ./configure CC="cc -nodtk" On Solaris, don't put `/usr/ucb' early in your `PATH'. This directory contains several dysfunctional programs; working variants of these programs are available in `/usr/bin'. So, if you need `/usr/ucb' in your `PATH', put it _after_ `/usr/bin'. On Haiku, software installed for all users goes in `/boot/common', not `/usr/local'. It is recommended to use the following options: ./configure --prefix=/boot/common Specifying the System Type ========================== There may be some features `configure' cannot figure out automatically, but needs to determine by the type of machine the package will run on. Usually, assuming the package is built to be run on the _same_ architectures, `configure' can figure that out, but if it prints a message saying it cannot guess the machine type, give it the `--build=TYPE' option. TYPE can either be a short name for the system type, such as `sun4', or a canonical name which has the form: CPU-COMPANY-SYSTEM where SYSTEM can have one of these forms: OS KERNEL-OS See the file `config.sub' for the possible values of each field. If `config.sub' isn't included in this package, then this package doesn't need to know the machine type. If you are _building_ compiler tools for cross-compiling, you should use the option `--target=TYPE' to select the type of system they will produce code for. If you want to _use_ a cross compiler, that generates code for a platform different from the build platform, you should specify the "host" platform (i.e., that on which the generated programs will eventually be run) with `--host=TYPE'. Sharing Defaults ================ If you want to set default values for `configure' scripts to share, you can create a site shell script called `config.site' that gives default values for variables like `CC', `cache_file', and `prefix'. `configure' looks for `PREFIX/share/config.site' if it exists, then `PREFIX/etc/config.site' if it exists. Or, you can set the `CONFIG_SITE' environment variable to the location of the site script. A warning: not all `configure' scripts look for a site script. Defining Variables ================== Variables not defined in a site shell script can be set in the environment passed to `configure'. However, some packages may run configure again during the build, and the customized values of these variables may be lost. In order to avoid this problem, you should set them in the `configure' command line, using `VAR=value'. For example: ./configure CC=/usr/local2/bin/gcc causes the specified `gcc' to be used as the C compiler (unless it is overridden in the site shell script). Unfortunately, this technique does not work for `CONFIG_SHELL' due to an Autoconf bug. Until the bug is fixed you can use this workaround: CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash `configure' Invocation ====================== `configure' recognizes the following options to control how it operates. `--help' `-h' Print a summary of all of the options to `configure', and exit. `--help=short' `--help=recursive' Print a summary of the options unique to this package's `configure', and exit. The `short' variant lists options used only in the top level, while the `recursive' variant lists options also present in any nested packages. `--version' `-V' Print the version of Autoconf used to generate the `configure' script, and exit. `--cache-file=FILE' Enable the cache: use and save the results of the tests in FILE, traditionally `config.cache'. FILE defaults to `/dev/null' to disable caching. `--config-cache' `-C' Alias for `--cache-file=config.cache'. `--quiet' `--silent' `-q' Do not print messages saying which checks are being made. To suppress all normal output, redirect it to `/dev/null' (any error messages will still be shown). `--srcdir=DIR' Look for the package's source code in directory DIR. Usually `configure' can determine that directory automatically. `--prefix=DIR' Use DIR as the installation prefix. *note Installation Names:: for more details, including other options available for fine-tuning the installation locations. `--no-create' `-n' Run the configure checks, but stop before creating any output files. `configure' also accepts some other, not widely useful, options. Run `configure --help' for more details. portaudio/bindings/cpp/bin/0000755000076400007660000000000012272324571014704 5ustar

In other projects, it is set to # `$srcdir', `$srcdir/..', or `$srcdir/../..'. # # Of course, Automake must honor this variable whenever it calls a # tool from the auxiliary directory. The problem is that $srcdir (and # therefore $ac_aux_dir as well) can be either absolute or relative, # depending on how configure is run. This is pretty annoying, since # it makes $ac_aux_dir quite unusable in subdirectories: in the top # source directory, any form will work fine, but in subdirectories a # relative path needs to be adjusted first. # # $ac_aux_dir/missing # fails when called from a subdirectory if $ac_aux_dir is relative # $top_srcdir/$ac_aux_dir/missing # fails if $ac_aux_dir is absolute, # fails when called from a subdirectory in a VPATH build with # a relative $ac_aux_dir # # The reason of the latter failure is that $top_srcdir and $ac_aux_dir # are both prefixed by $srcdir. In an in-source build this is usually # harmless because $srcdir is `.', but things will broke when you # start a VPATH build or use an absolute $srcdir. # # So we could use something similar to $top_srcdir/$ac_aux_dir/missing, # iff we strip the leading $srcdir from $ac_aux_dir. That would be: # am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"` # and then we would define $MISSING as # MISSING="\${SHELL} $am_aux_dir/missing" # This will work as long as MISSING is not called from configure, because # unfortunately $(top_srcdir) has no meaning in configure. # However there are other variables, like CC, which are often used in # configure, and could therefore not use this "fixed" $ac_aux_dir. # # Another solution, used here, is to always expand $ac_aux_dir to an # absolute PATH.

Install CMake if you haven't got it already ([http://www.cmake.org], minimum version required is 2.8). 2. If you want ASIO support you need to D/L the ASIO2 SDK from Steinberg, and place it according to \ref compile_windows_asio_msvc 3. Run the CMake GUI application and browse to source files directory and build directory: a. The source files directory ("Where is the source code") is where the portaudio CMakeLists.txt file is located. b. The build directory ("Where to build the binaries") is pretty much anywhere you like. A common practice though is to have the build directory located outside the source files tree (a so called "out-of-source build") 4. Click Configure. This will prompt you to select which build files to generate. Note Only Microsoft Visual C++ build files currently supported! 5. In the CMake option list, enable the PORTAUDIO_xxx options you need, then click Configure again (Note that after this there are no options marked with red color) 6. Click Generate and you'll now (hopefully) have your VS build files in your previously defined build directory. Both ASIO and DirectX SDK are automatically searched for by the CMake script, so if you have DirectX SDK installed and have placed the ASIO2 SDK according to point 2 above, you should be able to build portaudio with !DirectSound and ASIO support. Should you later on decide to change a portaudio option, just jump in at step 5 above (MSVC will then prompt you to reload projects/solutions/workspace) --- Robert Bielik Back to the Tutorial: \ref tutorial_start */portaudio/doc/src/tutorial/start_stop_abort.dox0000644000076400007660000000507711707722265021076 0ustar philphil/** @page start_stop_abort Starting, Stopping and Aborting a Stream @ingroup tutorial @section tut_startstop1 Starting, Stopping and Aborting a Stream PortAudio will not start playing back audio until you start the stream. After calling Pa_StartStream(), PortAudio will start calling your callback function to perform the audio processing. @code err = Pa_StartStream( stream ); if( err != paNoError ) goto error; @endcode You can communicate with your callback routine through the data structure you passed in on the open call, or through global variables, or using other interprocess communication techniques, but please be aware that your callback function may be called at interrupt time when your foreground process is least expecting it. So avoid sharing complex data structures that are easily corrupted like double linked lists, and avoid using locks such as mutexs as this may cause your callback function to block and therefore drop audio. Such techniques may even cause deadlock on some platforms. PortAudio will continue to call your callback and process audio until you stop the stream. This can be done in one of several ways, but, before we do so, we'll want to see that some of our audio gets processed by sleeping for a few seconds. This is easy to do with Pa_Sleep(), which is used by many of the examples in the patests/ directory for exactly this purpose. Note that, for a variety of reasons, you can not rely on this function for accurate scheduling, so your stream may not run for exactly the same amount of time as you expect, but it's good enough for our example. @code /* Sleep for several seconds. */ Pa_Sleep(NUM_SECONDS*1000); @endcode Now we need to stop playback. There are several ways to do this, the simplest of which is to call Pa_StopStream(): @code err = Pa_StopStream( stream ); if( err != paNoError ) goto error; @endcode Pa_StopStream() is designed to make sure that the buffers you've processed in your callback are all played, which may cause some delay. Alternatively, you could call Pa_AbortStream(). On some platforms, aborting the stream is much faster and may cause some data processed by your callback not to be played. Another way to stop the stream is to return either paComplete, or paAbort from your callback. paComplete ensures that the last buffer is played whereas paAbort stops the stream as soon as possible. If you stop the stream using this technique, you will need to call Pa_StopStream() before starting the stream again.

You'll want to read the portaudio.h reference, which documents the entire V19 API for details, but we'll try to cover the basics here. @section tut_util2 Version Information PortAudio offers two functions to determine the PortAudio Version. This is most useful when you are using PortAudio as a dynamic library, but it may also be useful at other times. @code int Pa_GetVersion (void) const char * Pa_GetVersionText (void) @endcode @section tut_util3 Error Text PortAudio allows you to get error text from an error number. @code const char * Pa_GetErrorText (PaError errorCode) @endcode @section tut_util4 Stream State PortAudio Streams exist in 3 states: Active, Stopped, and Callback Stopped. If a stream is in callback stopped state, you'll need to stop it before you can start it again.

Although it may have lower performance that the callback method described earlier in this tutorial, blocking I/O is easier to understand and is, in some cases, more compatible with third party systems than the callback method. Most people starting audio programming also find Blocking I/O easier to learn. Blocking I/O works in much the same way as the callback method except that instead of providing a function to provide (or consume) audio data, you must feed data to (or consume data from) PortAudio at regular intervals, usually inside a loop. The example below, excepted from patest_read_write_wire.c, shows how to open the default device, and pass data from its input to its output for a set period of time. Note that we use the default high latency values to help avoid underruns since we are usually reading and writing audio data from a relatively low priority thread, and there is usually extra buffering required to make blocking I/O work. Note that not all API's implement Blocking I/O at this point, so for maximum portability or performance, you'll still want to use callbacks. @code /* -- initialize PortAudio -- */ err = Pa_Initialize(); if( err != paNoError ) goto error; /* -- setup input and output -- */ inputParameters.device = Pa_GetDefaultInputDevice(); /* default input device */ inputParameters.channelCount = NUM_CHANNELS; inputParameters.sampleFormat = PA_SAMPLE_TYPE; inputParameters.suggestedLatency = Pa_GetDeviceInfo( inputParameters.device )->defaultHighInputLatency ; inputParameters.hostApiSpecificStreamInfo = NULL; outputParameters.device = Pa_GetDefaultOutputDevice(); /* default output device */ outputParameters.channelCount = NUM_CHANNELS; outputParameters.sampleFormat = PA_SAMPLE_TYPE; outputParameters.suggestedLatency = Pa_GetDeviceInfo( outputParameters.device )->defaultHighOutputLatency; outputParameters.hostApiSpecificStreamInfo = NULL; /* -- setup stream -- */ err = Pa_OpenStream( &stream, &inputParameters, &outputParameters, SAMPLE_RATE, FRAMES_PER_BUFFER, paClipOff, /* we won't output out of range samples so don't bother clipping them */ NULL, /* no callback, use blocking API */ NULL ); /* no callback, so no callback userData */ if( err != paNoError ) goto error; /* -- start stream -- */ err = Pa_StartStream( stream ); if( err != paNoError ) goto error; printf("Wire on.

You may wish to read "portaudio.h" because it contains a complete description of the PortAudio functions and constants. Alternatively, you could browse the [http://www.portaudio.com/docs/v19-doxydocs/portaudio_8h.html "portaudio.h" Doxygen page] @code #include "portaudio.h" @endcode The next task is to write your own "callback" function. The "callback" is a function that is called by the PortAudio engine whenever it has captured audio data, or when it needs more audio data for output. Before we begin, it's important to realize that the callback is a delicate place. This is because some systems perform the callback in a special thread, or interrupt handler, and it is rarely treated the same as the rest of your code. In addition, if you want your audio to reach the speakers on time, you'll need to make sure whatever code you run in the callback runs quickly. What is safe or not safe will vary from platform to platform, but as a rule of thumb, don't do anything like allocating or freeing memory, reading or writing files, printf(), or anything else that might take an unbounded amount of time or rely on the OS or require a context switch. Ed: is this still true?: Also do not call any PortAudio functions in the callback except for Pa_StreamTime() and Pa_GetCPULoad(). Your callback function must return an int and accept the exact parameters specified in this typedef: @code typedef int PaStreamCallback( const void *input, void *output, unsigned long frameCount, const PaStreamCallbackTimeInfo* timeInfo, PaStreamCallbackFlags statusFlags, void *userData ) ; @endcode Here is an example callback function from the test file "patests/patest_saw.c". It calculates a simple left and right sawtooth signal and writes it to the output buffer. Notice that in this example, the signals are of float data type. The signals must be between -1.0 and +1.0. You can also use 16 bit integers or other formats which are specified during setup, but floats are easiest to work with. You can pass a pointer to your data structure through PortAudio which will appear as userData. @code typedef struct { float left_phase; float right_phase; } paTestData; /* This routine will be called by the PortAudio engine when audio is needed. ** It may called at interrupt level on some machines so don't do anything ** that could mess up the system like calling malloc() or free(). */ static int patestCallback( const void *inputBuffer, void *outputBuffer, unsigned long framesPerBuffer, const PaStreamCallbackTimeInfo* timeInfo, PaStreamCallbackFlags statusFlags, void *userData ) { /* Cast data passed through stream to our structure. */ paTestData *data = (paTestData*)userData; float *out = (float*)outputBuffer; unsigned int i; (void) inputBuffer; /* Prevent unused variable warning. */ for( i=0; ileft_phase; /* left */ *out++ = data->right_phase; /* right */ /* Generate simple sawtooth phaser that ranges between -1.0 and 1.0. */ data->left_phase += 0.01f; /* When signal reaches top, drop back down. */ if( data->left_phase >= 1.0f ) data->left_phase -= 2.0f; /* higher pitch so we can distinguish left and right. */ data->right_phase += 0.03f; if( data->right_phase >= 1.0f ) data->right_phase -= 2.0f; } return 0; } @endcode Previous: \ref tutorial_start | Next: \ref initializing_portaudio */portaudio/doc/src/tutorial/compile_mac_coreaudio.dox0000644000076400007660000001535012046770722022000 0ustar philphil/** @page compile_mac_coreaudio Building Portaudio for Mac OS X @ingroup tutorial @section comp_mac_ca_1 Requirements * OS X 10.4 or later. PortAudio v19 currently only compiles and runs on OS X version 10.4 or later. Because of its heavy reliance on memory barriers, it's not clear how easy it would be to back-port PortAudio to OS X version 10.3. Leopard support requires the 2007 snapshot or later. * Apple's Xcode and its related tools installed in the default location. There is no Xcode project for PortAudio. * Mac 10.4 SDK. Look for "/Developer/SDKs/MacOSX10.4u.sdk" folder on your system. It may be installed with XCode. If not then you can download it from Apple Developer Connection. http://connect.apple.com/ @section comp_mac_ca_2 Building To build PortAudio, simply use the Unix-style "./configure && make": @code ./configure && make @endcode You do not need to do "make install", and we don't recommend it; however, you may be using software that instructs you to do so, in which case you should follow those instructions. (Note from Phil: I had to do "sudo make install" after the command above, otherwise XCode complained that it could not find "/usr/local/lib/libportaudio.dylib" when I compiled an example.) The result of these steps will be a file named "libportaudio.dylib" in the directory "usr/local/lib/". By default, this will create universal binaries and therefore requires the Universal SDK from Apple, included with XCode 2.1 and higher. @section comp_mac_ca_3 Other Build Options There are a variety of other options for building PortAudio. The default described above is recommended as it is the most supported and tested; however, your needs may differ and require other options, which are described below. @subsection comp_mac_ca_3.1 Building Non-Universal Libraries By default, PortAudio is built as a universal binary. This includes 64-bit versions if you are compiling on 10.5, Leopard. If you want a "thin", or single architecture library, you have two options: * build a non-universal library using configure options. * use lipo(1) on whatever part of the library you plan to use. Note that the first option may require an extremely recent version of PortAudio (February 5th '08 at least). @subsection comp_mac_ca_3.2 Building with --disable-mac-universal To build a non-universal library for the host architecture, simply use the --disable-mac-universal option with configure. @code ./configure --disable-mac-universal && make @endcode The --disable-mac-universal option may also be used in conjunction with environment variables to give you more control over the universal binary build process. For example, to build a universal binary for the i386 and ppc architectures using the 10.4u sdk (which is the default on 10.4, but not 10.5), you might specify this configure command line: @code CFLAGS="-O2 -g -Wall -arch i386 -arch ppc -isysroot /Developer/SDKs/MacOSX10.4u.sdk -mmacosx-version-min=10.3" \ LDFLAGS="-arch i386 -arch ppc -isysroot /Developer/SDKs/MacOSX10.4u.sdk -mmacosx-version-min=10.3" \ ./configure --disable-mac-universal --disable-dependency-tracking @endcode For more info, see Apple's documentation on the matter: * http://developer.apple.com/technotes/tn2005/tn2137.html * http://developer.apple.com/documentation/Porting/Conceptual/PortingUnix/intro/chapter_1_section_1.html @subsection comp_mac_ca_3.3 Using lipo The second option is to build normally, and use lipo (1) to extract the architectures you want. For example, if you want a "thin", i386 library only: @code lipo lib/.libs/libportaudio.a -thin i386 -output libportaudio.a @endcode or if you want to extract a single architecture fat file: @code lipo lib/.libs/libportaudio.a -extract i386 -output libportaudio.a @endcode @subsection comp_mac_ca_3.4 Building With Debug Options By default, PortAudio on the mac is built without any debugging options. This is because asserts are generally inappropriate for a production environment and debugging information has been suspected, though not proven, to cause trouble with some interfaces. If you would like to compile with debugging, you must run configure with the appropriate flags. For example: @code ./configure --enable-mac-debug && make @endcode This will enable -g and disable -DNDEBUG which will effectively enable asserts. @section comp_mac_ca_4 Using the Library in XCode Projects If you are planning to follow the rest of the tutorial, several project types will work. You can create a "Standard Tool" under "Command Line Utility". If you are not following the rest of the tutorial, any type of project should work with PortAudio, but these instructions may not work perfectly. Once you've compiled PortAudio, the easiest and recommended way to use PortAudio in your XCode project is to add "/include/portaudio.h" and "/lib/.libs/libportaudio.a" to your project. Because "/lib/.libs/" is a hidden directory, you won't be able to navigate to it using the finder or the standard Mac OS file dialogs by clicking on files and folders. You can use command-shift-G in the finder to specify the exact path, or, from the shell, if you are in the portaudio directory, you can enter this command: @code open lib/.libs @endcode Then drag the "libportaudio.a" file into your XCode project and place it in the "External Frameworks and Libraries" group, if the project type has it. If not you can simply add it to the top level folder of the project. You will need to add the following frameworks to your XCode project: - CoreAudio.framework - AudioToolbox.framework - AudioUnit.framework - CoreServices.framework - Carbon.framework @section comp_mac_ca_5 Using the Library in Other Projects For gcc/Make style projects, include "include/portaudio.h" and link "libportaudio.a", and use the frameworks listed in the previous section. How you do so depends on your build. @section comp_mac_ca_6 Using Mac-only Extensions to PortAudio For additional, Mac-only extensions to the PortAudio interface, you may also want to grab "include/pa_mac_core.h". This file contains some special, mac-only features relating to sample-rate conversion, channel mapping, performance and device hogging. See "src/hostapi/coreaudio/notes.txt" for more details on these features. @section comp_mac_ca_7 What Happened to Makefile.darwin? Note, there used to be a special makefile just for darwin. This is no longer supported because you can build universal binaries from the standard configure routine. If you find this file in your directory structure it means you have an outdated version of PortAudio. @code make -f Makefile.darwin @endcode Back to the Tutorial: \ref tutorial_start */ portaudio/doc/src/tutorial/compile_windows.dox0000644000076400007660000001472712173772253020711 0ustar philphil/** @page compile_windows Building Portaudio for Windows using Microsoft Visual Studio @ingroup tutorial Below is a list of steps to build PortAudio into a dll and lib file. The resulting dll file may contain all five current win32 PortAudio APIs: MME, DirectSound, WASAPI, WDM/KS and ASIO, depending on the preprocessor definitions set in step 9 below. PortAudio can be compiled using Visual C++ Express Edition which is available free from Microsoft. If you do not already have a C++ development environment, simply download and install. These instructions have been observed to succeed using Visual Studio 2010 as well. 1) PortAudio for Windows requires the files dsound.h and dsconf.h. Download and install the DirectX SDK from http://www.microsoft.com/downloads/details.aspx?displaylang=en&FamilyID=3021d52b-514e-41d3-ad02-438a3ba730ba to obtain these files. If you installed the DirectX SDK then the !DirectSound libraries and header files should be found automatically by Visual !Studio/Visual C++. If you get an error saying dsound.h or dsconf.h is missing, you can declare these paths by hand. Alternatively, you can copy dsound.h and dsconf.h to portaudio\\include. There should also be a file named ''dsound.lib'' in C:\\Program Files\\Microsoft SDKs\\Windows\\v6.0A\\Lib. 2) For ASIO support, download the ASIO SDK from Steinberg at http://www.steinberg.net/en/company/developer.html. The SDK is free but you will need to set up a developer account with Steinberg. Copy the entire ASIOSDK2 folder into src\\hostapi\\asio\\. Rename it from ASIOSDK2 to ASIOSDK. To build without ASIO (or other host API) see the "Building without ASIO support" section below. 3) If you have Visual Studio 6.0, 7.0(VC.NET/2001) or 7.1(VC.2003), open portaudio.dsp and convert if needed. 4) If you have Visual Studio 2005, Visual C++ 2008 Express Edition or Visual Studio 2010, double click the portaudio.sln file located in build\\msvc\\. Doing so will open Visual Studio or Visual C++. Click "Finish" if a wizard appears. The sln file contains four configurations: Win32 and Win64 in both Release and Debug variants. @section comp_win1 For Visual Studio 2005, Visual C++ 2008 Express Edition or Visual Studio 2010 5) Open Project -> portaudio Properties and select "Configuration Properties" in the tree view. 6) Select "all configurations" in the "Configurations" combo box above. Select "All Platforms" in the "Platforms" combo box. 7) Now set a few options: C/C++ -> Optimization -> Omit frame pointers = Yes C/C++ -> Code Generation -> Runtime library = /MT Optional: C/C++ -> Code Generation -> Floating point model = fast NOTE: For most users it is not necessary to explicitly set the structure member alignment; the default should work fine. However some languages require, for example, 4-byte alignment. If you are having problems with portaudio.h structure members not being properly read or written to, it may be necessary to explicitly set this value by going to C/C++ -> Code Generation -> Struct member alignment and setting it to an appropriate value (four is a common value). If your compiler is configurable, you should ensure that it is set to use the same structure member alignment value as used for the PortAudio build. Click "Ok" when you have finished setting these parameters. @section comp_win2 Preprocessor Definitions Since the preprocessor definitions are different for each configuration and platform, you'll need to edit these individually for each configuration/platform combination that you want to modify using the "Configurations" and "Platforms" combo boxes. 8) To suppress PortAudio runtime debug console output, go to Project -> Properties -> Configuration Properties -> C/C++ -> Preprocessor. In the field 'Preprocessor Definitions', find PA_ENABLE_DEBUG_OUTPUT and remove it. The console will not output debug messages. 9) Also in the preprocessor definitions you need to explicitly define the audio APIs you wish to use. For Windows the available API definitions are: PA_USE_ASIO
PA_USE_DS (DirectSound)
PA_USE_WMME (MME)
PA_USE_WASAPI
PA_USE_WDMKS
PA_USE_SKELETON For each of these, the value of 0 indicates that support for this API should not be included. The value 1 indicates that support for this API should be included. @section comp_win3 Building As when setting Preprocessor definitions, building is a per-configuration per-platform process. Follow these instructions for each configuration/platform combination that you're interested in. 10) From the Build menu click Build -> Build solution. For 32-bit compilations, the dll file created by this process (portaudio_x86.dll) can be found in the directory build\\msvc\\Win32\\Release. For 64-bit compilations, the dll file is called portaudio_x64.dll, and is found in the directory build\\msvc\\x64\\Release. 11) Now, any project which requires portaudio can be linked with portaudio_x86.lib (or _x64) and include the relevant headers (portaudio.h, and/or pa_asio.h , pa_x86_plain_converters.h) You may want to add/remove some DLL entry points. Right now those 6 entries are not from portaudio.h: (from portaudio.def) @code ... PaAsio_GetAvailableLatencyValues @50 PaAsio_ShowControlPanel @51 PaUtil_InitializeX86PlainConverters @52 PaAsio_GetInputChannelName @53 PaAsio_GetOutputChannelName @54 PaUtil_SetLogPrintFunction @55 @endcode @section comp_win4 Building without ASIO support To build PortAudio without ASIO support you need to: 1) Make sure your project doesn't try to build any ASIO SDK files. If you're using one of the shipped projects, remove the ASIO related files from the project. 2) Make sure your project doesn't try to build the PortAudio ASIO implementation files: src\\hostapi\\pa_asio.cpp src\\hostapi\\iasiothiscallresolver.cpp If you're using one of the shipped projects, remove them from the project. 3) Define the preprocessor symbols in the project properties as described in step 9 above. In VS2005 this can be accomplished by selecting Project Properties -> Configuration Properties -> C/C++ -> Preprocessor -> Preprocessor Definitions. Omitting PA_USE_ASIO or setting it to 0 stops src\\os\\win\\pa_win_hostapis.c from trying to initialize the PortAudio ASIO implementation. 4) Remove PaAsio_* entry points from portaudio.def ----- David Viens, davidv@plogue.com Updated by Chris on 5/26/2011 Improvements by John Clements on 12/15/2011 Back to the Tutorial: \ref tutorial_start */portaudio/doc/src/tutorial/compile_windows_mingw.dox0000644000076400007660000000327211707722265022103 0ustar philphil/** @page compile_windows_mingw Building Portaudio for Windows with MinGW @ingroup tutorial @section comp_mingw1 Portaudio for Windows With MinGW The following document is still being reviewed = MinGW/MSYS = From the [http://www.mingw.org MinGW projectpage]: MinGW: A collection of freely available and freely distributable Windows specific header files and import libraries, augmenting the GNU Compiler Collection, (GCC), and its associated tools, (GNU binutils).

For instructions for building PortAudio (including ASIO support) using the bundled Visual Studio project file see the compiling instructions for \ref compile_windows. ASIO is a low latency audio API from Steinberg. To compile an ASIO application, you must first download the ASIO SDK from Steinberg. You also need to obtain ASIO drivers for your audio device. Download the ASIO SDK from Steinberg at http://www.steinberg.net/en/company/developer.html. The SDK is free but you will need to set up a developer account with Steinberg. This tutorial assumes that you have 3 directories set up at the same level (side by side), one containing PortAudio, one containing the ASIO SDK and one containing your Visual Studio project: @code /ASIOSDK2 /portaudio /DirContainingYourVisualStudioProject @endcode First, make sure that the Steinberg SDK and the portaudio files are "side by side" in the same directory. Open Microsoft Visual C++ and create a new blank Console exe Project/Workspace in that same directory. For example, the paths for all three groups might read like this: @code C:\Program Files\Microsoft Visual Studio\VC98\My Projects\ASIOSDK2 C:\Program Files\Microsoft Visual Studio\VC98\My Projects\portaudio C:\Program Files\Microsoft Visual Studio\VC98\My Projects\Sawtooth @endcode Next, add the following Steinberg ASIO SDK files to the project Source Files: @code asio.cpp (ASIOSDK2\common) asiodrivers.cpp (ASIOSDK2\host) asiolist.cpp (ASIOSDK2\host\pc) @endcode Then, add the following PortAudio files to the project Source Files: @code pa_asio.cpp (portaudio\src\hostapi\asio) pa_allocation.c (portaudio\src\common) pa_converters.c (portaudio\src\common) pa_cpuload.c (portaudio\src\common) pa_dither.c (portaudio\src\common) pa_front.c (portaudio\src\common) pa_process.c (portaudio\src\common) pa_ringbuffer.c (portaudio\src\common) pa_stream.c (portaudio\src\common) pa_trace.c (portaudio\src\common) pa_win_hostapis.c (portaudio\src\os\win) pa_win_util.c (portaudio\src\os\win) pa_win_waveformat.c (portaudio\src\os\win) pa_x86_plain_converters.c (portaudio\src\os\win) patest_saw.c (portaudio\test) (Or another file containing main() for the console exe to be built.) @endcode Although not strictly necessary, you may also want to add the following files to the project Header Files: @code portaudio.h (portaudio\include) pa_asio.h (portaudio\include) @endcode These header files define the interfaces to the PortAudio API. Next, go to Project Settings > All Configurations > C/C++ > Preprocessor > Preprocessor definitions and add PA_USE_ASIO=1 to any entries that might be there. eg: WIN32;_CONSOLE;_MBCS changes to WIN32;_CONSOLE,_MBCS;PA_USE_ASIO=1 Then, on the same Project Settings tab, go down to Additional include directories: and enter the following relative include paths. @code ..\portaudio\include,..\portaudio\src\common,..\asiosdk2\common,..\asiosdk2\host,..\asiosdk2\host\pc @endcode You'll need to make sure the relative paths are correct for the particular directory layout you're using. The above should work fine if you use the side-by-side layout we recommended earlier. You should now be able to build any of the test executables in the portaudio\test directory. We suggest that you start with patest_saw.c because it's one of the simplest test files. --- Chris Share, Tom McCandless, Ross Bencina [wiki:UsingThePortAudioSvnRepository SVN instructions] Back to the Tutorial: \ref tutorial_start */portaudio/doc/src/tutorial/querying_devices.dox0000644000076400007660000001100312020251145021013 0ustar philphil/** @page querying_devices Enumerating and Querying PortAudio Devices @ingroup tutorial @section tut_query1 Querying Devices It is often fine to use the default device as we did previously in this tutorial, but there are times when you'll want to explicitly choose the device from a list of available devices on the system. To see a working example of this, check out pa_devs.c in the tests/ directory of the PortAudio source code. To do so, you'll need to first initialize PortAudio and Query for the number of Devices: @code int numDevices; numDevices = Pa_GetDeviceCount(); if( numDevices < 0 ) { printf( "ERROR: Pa_CountDevices returned 0x%x\n", numDevices ); err = numDevices; goto error; } @endcode If you want to get information about each device, simply loop through as follows: @code const PaDeviceInfo *deviceInfo; for( i=0; idefaultLowInputLatency ; inputParameters.hostApiSpecificStreamInfo = NULL; //See you specific host's API docs for info on using this field bzero( &outputParameters, sizeof( outputParameters ) ); //not necessary if you are filling in all the fields outputParameters.channelCount = outChan; outputParameters.device = outDevNum; outputParameters.hostApiSpecificStreamInfo = NULL; outputParameters.sampleFormat = paFloat32; outputParameters.suggestedLatency = Pa_GetDeviceInfo(outDevNum)->defaultLowOutputLatency ; outputParameters.hostApiSpecificStreamInfo = NULL; //See you specific host's API docs for info on using this field err = Pa_OpenStream( &stream, &inputParameters, &outputParameters, srate, framesPerBuffer, paNoFlag, //flags that can be used to define dither, clip settings and more portAudioCallback, //your callback function (void *)this ); //data to be passed to callback.

It is recommended that you use the ALSA sound API. The PortAudio configure script will look for the ALSA SDK. You can install the ALSA SDK on Ubuntu using: @code sudo apt-get install libasound-dev @endcode You might need to use yum, or some other package manager, instead of apt-get on your machine. If you do not install ALSA then you might get a message when testing that says you have no audio devices. You can find out more about ALSA here: http://www.alsa-project.org/ @section comp_linux2 Configuring and Compiling PortAudio You can build PortAudio in Linux Environments using the standard configure/make tools: @code ./configure && make @endcode That will build PortAudio using Jack, ALSA and OSS in whatever combination they are found on your system. For example, if you have Jack and OSS but not ALSA, it will build using Jack and OSS but not ALSA. This step also builds a number of tests, which can be found in the bin directory of PortAudio. It's a good idea to run some of these tests to make sure PortAudio is working correctly. @section comp_linux3 Using PortAudio in your Projects To use PortAudio in your apps, you can simply install the .so files: @code make install @endcode Projects built this way will expect PortAudio to be installed on target systems in order to run. If you want to build a more self-contained binary, you may use the libportaudio.a file: @code cp lib/.libs/libportaudio.a /YOUR/PROJECT/DIR @endcode You may also need to copy portaudio.h, located in the include/ directory of PortAudio into your project. Note that you will usually need to link with the approriate libraries that you used, such as ALSA and JACK, as well as with librt and libpthread. For example: @code gcc -lrt -lasound -ljack -lpthread -o YOUR_BINARY main.c libportaudio.a @endcode @section comp_linux4 Linux Extensions Note that the ALSA PortAudio back-end adds a few extensions to the standard API that you may take advantage of. To use these functions be sure to include the pa_linux_alsa.h file found in the include file in the PortAudio folder. This file contains further documentation on the following functions: PaAlsaStreamInfo/PaAlsa_InitializeStreamInfo:: Objects of the !PaAlsaStreamInfo type may be used for the !hostApiSpecificStreamInfo attribute of a !PaStreamParameters object, in order to specify the name of an ALSA device to open directly. Specify the device via !PaAlsaStreamInfo.deviceString, after initializing the object with PaAlsa_InitializeStreamInfo. PaAlsa_EnableRealtimeScheduling:: PA ALSA supports real-time scheduling of the audio callback thread (using the FIFO pthread scheduling policy), via the extension PaAlsa_EnableRealtimeScheduling. Call this on the stream before starting it with the enableScheduling parameter set to true or false, to enable or disable this behaviour respectively. PaAlsa_GetStreamInputCard:: Use this function to get the ALSA-lib card index of the stream's input device. PaAlsa_GetStreamOutputCard:: Use this function to get the ALSA-lib card index of the stream's output device. Of particular importance is PaAlsa_EnableRealtimeScheduling, which allows ALSA to run at a high priority to prevent ordinary processes on the system from preempting audio playback. Without this, low latency audio playback will be irregular and will contain frequent drop-outs. @section comp_linux5 Linux Debugging Eliot Blennerhassett writes: On linux build, use e.g. "libtool gdb bin/patest_sine8" to debug that program. This is because on linux bin/patest_sine8 is a libtool shell script that wraps bin/.libs/patest_sine8 and allows it to find the appropriate libraries within the build tree. */portaudio/doc/src/tutorial/exploring.dox0000644000076400007660000000133711707723042017501 0ustar philphil/** @page exploring Exploring PortAudio @ingroup tutorial Now that you have a good idea of how PortAudio works, you can try out the example programs.

You can specify whether you want audio input and/or output, how many channels, the data format, sample rate, etc. Opening a ''default'' stream means opening the default input and output devices, which saves you the trouble of getting a list of devices and choosing one from the list. (We'll see how to do that later.) @code #define SAMPLE_RATE (44100) static paTestData data; ..... PaStream *stream; PaError err; /* Open an audio I/O stream. */ err = Pa_OpenDefaultStream( &stream, 0, /* no input channels */ 2, /* stereo output */ paFloat32, /* 32 bit floating point output */ SAMPLE_RATE, 256, /* frames per buffer, i.e. the number of sample frames that PortAudio will request from the callback. Many apps may want to use paFramesPerBufferUnspecified, which tells PortAudio to pick the best, possibly changing, buffer size.*/ patestCallback, /* this is your callback function */ &data ); /*This is a pointer that will be passed to your callback*/ if( err != paNoError ) goto error; @endcode The data structure and callback are described in \ref writing_a_callback. The above example opens the stream for writing, which is sufficient for playback. It is also possible to open a stream for reading, to do recording, or both reading and writing, for simultaneous recording and playback or even real-time audio processing. If you plan to do playback and recording at the same time, open only one stream with valid input and output parameters. There are some caveats to note about simultaneous read/write: - Some platforms can only open a read/write stream using the same device. - Although multiple streams can be opened, it is difficult to synchronize them. - Some platforms don't support opening multiple streams on the same device. - Using multiple streams may not be as well tested as other features. - The PortAudio library calls must be made from the same thread or synchronized by the user.

If you'd prefer to start with a top-down overview of the PortAudio API, check out the @ref api_overview. @section tut_start1 Downloading First thing you need to do is download the PortAudio source code either as a tarball from the website, or from the Subversion Repository. @section tut_start2 Compiling Once you've downloaded PortAudio you'll need to compile it, which of course, depends on your environment: - Windows - \ref compile_windows - \ref compile_windows_mingw - \ref compile_windows_asio_msvc - \ref compile_cmake - Mac OS X - \ref compile_mac_coreaudio - POSIX - \ref compile_linux Many platforms with GCC/make can use the simple ./configure && make combination and simply use the resulting libraries in their code. @section tut_start3 Programming with PortAudio Below are the steps to writing a PortAudio application using the callback technique: - Write a callback function that will be called by PortAudio when audio processing is needed. - Initialize the PA library and open a stream for audio I/O. - Start the stream. Your callback function will be now be called repeatedly by PA in the background. - In your callback you can read audio data from the inputBuffer and/or write data to the outputBuffer. - Stop the stream by returning 1 from your callback, or by calling a stop function. - Close the stream and terminate the library. In addition to this "Callback" architecture, V19 also supports a "Blocking I/O" model which uses read and write calls which may be more familiar to non-audio programmers. Note that at this time, not all APIs support this functionality. In this tutorial, we'll show how to use the callback architecture to play a sawtooth wave. Much of the tutorial is taken from the file paex_saw.c, which is part of the PortAudio distribution. When you're done with this tutorial, you'll be armed with the basic knowledge you need to write an audio program. If you need more sample code, look in the "examples" and "test" directory of the PortAudio distribution. Another great source of info is the portaudio.h Doxygen page, which documents the entire V19 API.

It describes how all of the PortAudio data types and functions fit together. It provides links to the documentation for each function and data type. You can find all of the detailed documentation for each API function and data type on the portaudio.h page. @section introduction Introduction PortAudio provides a uniform application programming interface (API) across all supported platforms. You can think of the PortAudio library as a wrapper that converts calls to the PortAudio API into calls to platform-specific native audio APIs. Operating systems often offer more than one native audio API and some APIs (such as JACK) may be available on multiple target operating systems. PortAudio supports all the major native audio APIs on each supported platform. The diagram below illustrates the relationship between your application, PortAudio, and the supported native audio APIs: @image html portaudio-external-architecture-diagram.png PortAudio provides a uniform interface to native audio APIs. However, it doesn't always provide totally uniform functionality. There are cases where PortAudio is limited by the capabilities of the underlying native audio API. For example, PortAudio doesn't provide sample rate conversion if you request a sample rate that is not supported by the native audio API. Another example is that the ASIO SDK only allows one device to be open at a time, so PortAudio/ASIO doesn't currently support opening multiple ASIO devices simultaneously. @section key_abstractions Key abstractions: Host APIs, Devices and Streams The PortAudio processing model includes three main abstractions: Host APIs, audio Devices and audio Streams. Host APIs represent platform-specific native audio APIs. Some examples of Host APIs are Core Audio on Mac OS, WMME and DirectSound on Windows and OSS and ALSA on Linux. The diagram in the previous section shows many of the supported native APIs. Sometimes it's useful to know which Host APIs you're dealing with, but it is easy to use PortAudio without ever interacting directly with the Host API abstraction. Devices represent individual hardware audio interfaces or audio ports on the host platform. Devices have names and certain capabilities such as supported sample rates and the number of supported input and output channels. PortAudio provides functions to enumerate available Devices and to query for Device capabilities. Streams manage active audio input and output from and to Devices. Streams may be half duplex (input or output) or full duplex (simultaneous input and output). Streams operate at a specific sample rate with particular sample formats, buffer sizes and internal buffering latencies. You specify these parameters when you open the Stream. Audio data is communicated between a Stream and your application via a user provided asynchronous callback function or by invoking synchronous read and write functions. PortAudio supports audio input and output in a variety of sample formats: 8, 16, 24 and 32 bit integer formats and 32 bit floating point, irrespective of the formats supported by the native audio API. PortAudio also supports multichannel buffers in both interleaved and non-interleaved (separate buffer per channel) formats and automatically performs conversion when necessary. If requested, PortAudio can clamp out-of range samples and/or dither to a native format. The PortAudio API offers the following functionality: - Initialize and terminate the library - Enumerate available Host APIs - Enumerate available Devices either globally, or within each Host API - Discover default or recommended Devices and Device settings - Discover Device capabilities such as supported audio data formats and sample rates - Create and control audio Streams to acquire audio from and output audio to Devices - Provide Stream timing information to support synchronising audio with other parts of your application - Retrieve version and error information. These functions are described in more detail below. @section top_level_functions Initialization, termination and utility functions The PortAudio library must be initialized before it can be used and terminated to clean up afterwards. You initialize PortAudio by calling Pa_Initialize() and clean up by calling Pa_Terminate(). You can query PortAudio for version information using Pa_GetVersion() to get a numeric version number and Pa_GetVersionText() to get a string. The size in bytes of the various sample formats represented by the @ref PaSampleFormat enumeration can be obtained using Pa_GetSampleSize(). Pa_Sleep() sleeps for a specified number of milliseconds. This isn't intended for use in production systems; it's provided only as a simple portable way to implement tests and examples where the main thread sleeps while audio is acquired or played by an asynchronous callback function. @section host_apis Host APIs A Host API acts as a top-level grouping for all of the Devices offered by a single native platform audio API. Each Host API has a unique type identifier, a name, zero or more Devices, and nominated default input and output Devices. Host APIs are usually referenced by index: an integer of type @ref PaHostApiIndex that ranges between zero and Pa_GetHostApiCount() - 1. You can enumerate all available Host APIs by counting across this range. You can retrieve the index of the default Host API by calling Pa_GetDefaultHostApi(). Information about a Host API, such as it's name and default devices, is stored in a @ref PaHostApiInfo structure. You can retrieve a pointer to a particular Host API's @ref PaHostApiInfo structure by calling Pa_GetHostApiInfo() with the Host API's index as a parameter. Most PortAudio functions reference Host APIs by @ref PaHostApiIndex indices. Each Host API also has a unique type identifier defined in the @ref PaHostApiTypeId enumeration. You can call Pa_HostApiTypeIdToHostApiIndex() to retrieve the current @ref PaHostApiIndex for a particular @ref PaHostApiTypeId. @section devices Devices A Device represents an audio endpoint provided by a particular native audio API. This usually corresponds to a specific input or output port on a hardware audio interface, or to the interface as a whole. Each Host API operates independently, so a single physical audio port may be addressable via different Devices exposed by different Host APIs. A Device has a name, is associated with a Host API, and has a maximum number of supported input and output channels. PortAudio provides recommended default latency values and a default sample rate for each Device. To obtain more detailed information about device capabilities you can call Pa_IsFormatSupported() to query whether it is possible to open a Stream using particular Devices, parameters and sample rate. Although each Device conceptually belongs to a specific Host API, most PortAudio functions and data structures refer to Devices using a global, Host API-independent index of type @ref PaDeviceIndex – an integer of that ranges between zero and Pa_GetDeviceCount() - 1. The reasons for this are partly historical but it also makes it easy for applications to ignore the Host API abstraction and just work with Devices and Streams. If you want to enumerate Devices belonging to a particular Host API you can count between 0 and PaHostApiInfo::deviceCount - 1. You can convert this Host API-specific index value to a global @ref PaDeviceIndex value by calling Pa_HostApiDeviceIndexToDeviceIndex(). Information about a Device is stored in a @ref PaDeviceInfo structure. You can retrieve a pointer to a Devices's @ref PaDeviceInfo structure by calling Pa_GetDeviceInfo() with the Device's index as a parameter. You can retrieve the indices of the global default input and output devices using Pa_GetDefaultInputDevice() and Pa_GetDefaultOutputDevice(). Default Devices for each Host API are stored in the Host API's @ref PaHostApiInfo structures. For an example of enumerating devices and printing information about their capabilities see the pa_devs.c program in the test directory of the PortAudio distribution. @section streams Streams A Stream represents an active flow of audio data between your application and one or more audio Devices. A Stream operates at a specific sample rate with specific sample formats and buffer sizes. @subsection io_methods I/O Methods: callback and read/write PortAudio offers two methods for communicating audio data between an open Stream and your Application: (1) an asynchronous callback interface, where PortAudio calls a user defined callback function when new audio data is available or required, and (2) synchronous read and write functions which can be used in a blocking or non-blocking manner. You choose between the two methods when you open a Stream. The two methods are discussed in more detail below. @subsection opening_and_closing_streams Opening and Closing Streams You call Pa_OpenStream() to open a Stream, specifying the Device(s) to use, the number of input and output channels, sample formats, suggested latency values and flags that control dithering, clipping and overflow handling. You specify many of these parameters in two PaStreamParameters structures, one for input and one for output. If you're using the callback I/O method you also pass a callback buffer size, callback function pointer and user data pointer. Devices may be full duplex (supporting simultaneous input and output) or half duplex (supporting input or output) – usually this reflects the structure of the underlying native audio API. When opening a Stream you can specify one full duplex Device for both input and output, or two different Devices for input and output. Some Host APIs only support full-duplex operation with a full-duplex device (e.g. ASIO) but most are able to aggregate two half duplex devices into a full duplex Stream. PortAudio requires that all devices specified in a call to Pa_OpenStream() belong to the same Host API. A successful call to Pa_OpenStream() creates a pointer to a @ref PaStream – an opaque handle representing the open Stream. All PortAudio API functions that operate on open Streams take a pointer to a @ref PaStream as their first parameter. PortAudio also provides Pa_OpenDefaultStream() – a simpler alternative to Pa_OpenStream() which you can use when you want to open the default audio Device(s) with default latency parameters. You call Pa_CloseStream() to close a Stream when you've finished using it. @subsection starting_and_stopping_streams Starting and Stopping Streams Newly opened Streams are initially stopped. You call Pa_StartStream() to start a Stream. You can stop a running Stream using Pa_StopStream() or Pa_AbortStream() (the Stop function plays out all internally queued audio data, while Abort tries to stop as quickly as possible). An open Stream can be started and stopped multiple times. You can call Pa_IsStreamStopped() to query whether a Stream is running or stopped. By calling Pa_SetStreamFinishedCallback() it is possible to register a special @ref PaStreamFinishedCallback that will be called when the Stream has completed playing any internally queued buffers. This can be used in conjunction with the @ref paComplete stream callback return value (see below) to avoid blocking on a call to Pa_StopStream() while queued audio data is still playing. @subsection callback_io_method The Callback I/O Method So-called 'callback Streams' operate by periodically invoking a callback function you supply to Pa_OpenStream(). The callback function must implement the @ref PaStreamCallback signature. It gets called by PortAudio every time PortAudio needs your application to consume or produce audio data. The callback is passed pointers to buffers containing the audio to process. The format (interleave, sample data type) and size of these buffers is determined by the parameters passed to Pa_OpenStream() when the Stream was opened. Stream callbacks usually return @ref paContinue to indicate that PortAudio should keep the stream running. It is possible to deactivate a Stream from the stream callback by returning either @ref paComplete or @ref paAbort. In this case the Stream enters a deactivated state after the last buffer has finished playing (@ref paComplete) or as soon as possible (@ref paAbort). You can detect the deactivated state by calling Pa_IsStreamActive() or by using Pa_SetStreamFinishedCallback() to subscribe to a stream finished notification. Note that even if the stream callback returns @ref paComplete it's still necessary to call Pa_StopStream() or Pa_AbortStream() to enter the stopped state. Many of the tests in the /tests directory of the PortAudio distribution implement PortAudio stream callbacks. For example see: patest_sine.c (audio output), patest_record.c (audio input), patest_wire.c (audio pass-through) and pa_fuzz.c (simple audio effects processing). IMPORTANT: The stream callback function often needs to operate with very high or real-time priority. As a result there are strict requirements placed on the type of code that can be executed in a stream callback. In general this means avoiding any code that might block, including: acquiring locks, calling OS API functions including allocating memory. With the exception of Pa_GetStreamCpuLoad() you may not call PortAudio API functions from within the stream callback. @subsection read_write_io_method The Read/Write I/O Method As an alternative to the callback I/O method, PortAudio provides a synchronous read/write interface for acquiring and playing audio. This can be useful for applications that don't require the lowest possibly latency, or don't warrant the increased complexity of synchronising with an asynchronous callback funciton. This I/O method is also useful when calling PortAudio from programming languages that don't support asynchronous callbacks. To open a Stream in read/write mode you pass a NULL stream callback function pointer to Pa_OpenStream(). To write audio data to a Stream call Pa_WriteStream() and to read data call Pa_ReadStream(). These functions will block if the internal buffers are full, making them safe to call in a tight loop. If you want to avoid blocking you can query the amount of available read or write space using Pa_GetStreamReadAvailable() or Pa_GetStreamWriteAvailable() and use the returned values to limit the amount of data you read or write. For examples of the read/write I/O method see the following examples in the /tests directory of the PortAudio distribution: patest_read_record.c (audio input), patest_write_sine.c (audio output), patest_read_write_wire.c (audio pass-through). @subsection stream_info Retrieving Stream Information You can retrieve information about an open Stream by calling Pa_GetStreamInfo(). This returns a @ref PaStreamInfo structure containing the actual input and output latency and sample rate of the stream. It's possible for these values to be different from the suggested values passed to Pa_OpenStream(). When using a callback stream you can call Pa_GetStreamCpuLoad() to retrieve a rough estimate of the amount of CPU time your callback function is using. @subsection stream_timing Stream Timing Information When using the callback I/O method your stream callback function receives timing information via a pointer to a PaStreamCallbackTimeInfo structure. This structure contains the current time along with the estimated hardware capture and playback time of the first sample of the input and output buffers. All times are measured in seconds relative to a Stream-specific clock. The current Stream clock time can be retrieved using Pa_GetStreamTime(). You can use the stream callback @ref PaStreamCallbackTimeInfo times in conjunction with timestamps returned by Pa_GetStreamTime() to implement time synchronization schemes such as time aligning your GUI display with rendered audio, or maintaining synchronization between MIDI and audio playback. @section error_handling Error Handling Most PortAudio functions return error codes using values from the @ref PaError enumeration. All error codes are negative values. Some functions return values greater than or equal to zero for normal results and a negative error code in case of error. You can convert @ref PaError error codes to human readable text by calling Pa_GetErrorText(). PortAudio usually tries to translate error conditions into portable @ref PaError error codes. However if an unexpected error is encountered the @ref paUnanticipatedHostError code may be returned. In this case a further mechanism is provided to query for Host API-specific error information. If PortAudio returns @ref paUnanticipatedHostError you can call Pa_GetLastHostErrorInfo() to retrieve a pointer to a @ref PaHostErrorInfo structure that provides more information, including the Host API that encountered the error, a native API error code and error text. @section host_api_extensions Host API and Platform-specific Extensions The public PortAudio API only exposes functionality that can be provided across all target platforms. In some cases individual native audio APIs offer unique functionality. Some PortAudio Host APIs expose this functionality via Host API-specific extensions. Examples include access to low-level buffering and priority parameters, opening a Stream with only a subset of a Device's channels, or accessing channel metadata such as channel names. Host API-specific extensions are provided in the form of additional functions and data structures defined in Host API-specific header files found in the /include directory. The @ref PaStreamParameters structure passed to Pa_IsFormatSupported() and Pa_OpenStream() has a field named @ref PaStreamParameters::hostApiSpecificStreamInfo that is sometimes used to pass low level information when opening a Stream. See the documentation for the individual Host API-specific header files for details of the extended functionality they expose: - pa_asio.h - pa_jack.h - pa_linux_alsa.h - pa_mac_core.h - pa_win_ds.h - pa_win_wasapi.h - pa_win_wmme.h - pa_win_waveformat.h */portaudio/doc/src/mainpage.dox0000644000076400007660000000601612020453556015406 0ustar philphil/* doxygen index page */ /** @mainpage @section overview Overview PortAudio is a cross-platform, open-source C language library for real-time audio input and output. The library provides functions that allow your software to acquire and output real-time audio streams from your computer's hardware audio interfaces. It is designed to simplify writing cross-platform audio applications, and also to simplify the development of audio software in general by hiding the complexities of dealing directly with each native audio API. PortAudio is used to implement sound recording, editing and mixing applications, software synthesizers, effects processors, music players, internet telephony applications, software defined radios and more. Supported platforms include MS Windows, Mac OS X and Linux. Third-party language bindings make it possible to call PortAudio from other programming languages including @ref java_binding "Java", C++, C#, Python, PureBasic, FreePascal and Lazarus. @section start_here Start here - @ref api_overview

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 speciying '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. 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.

They consume, process or generate audio in response to requests from an active PortAudio stream. When a stream is running, PortAudio calls the stream callback periodically. The callback function is responsible for processing buffers of audio samples passed via the input and output parameters. The PortAudio stream callback runs at very high or real-time priority. It is required to consistently meet its time deadlines. Do not allocate memory, access the file system, call library functions or call other functions from the stream callback that may block or take an unpredictable amount of time to complete. In order for a stream to maintain glitch-free operation the callback must consume and return audio data faster than it is recorded and/or played. PortAudio anticipates that each callback invocation may execute for a duration approaching the duration of frameCount audio frames at the stream sample rate. It is reasonable to expect to be able to utilise 70% or more of the available CPU time in the PortAudio callback. However, due to buffer size adaption and other factors, not all host APIs are able to guarantee audio stability under heavy CPU load with arbitrary fixed callback buffer sizes. When high callback CPU utilisation is required the most robust behavior can be achieved by using paFramesPerBufferUnspecified as the Pa_OpenStream() framesPerBuffer parameter. @param input and @param output are either arrays of interleaved samples or; if non-interleaved samples were requested using the paNonInterleaved sample format flag, an array of buffer pointers, one non-interleaved buffer for each channel. The format, packing and number of channels used by the buffers are determined by parameters to Pa_OpenStream(). @param frameCount The number of sample frames to be processed by the stream callback. @param timeInfo Timestamps indicating the ADC capture time of the first sample in the input buffer, the DAC output time of the first sample in the output buffer and the time the callback was invoked. See PaStreamCallbackTimeInfo and Pa_GetStreamTime() @param statusFlags Flags indicating whether input and/or output buffers have been inserted or will be dropped to overcome underflow or overflow conditions. @param userData The value of a user supplied pointer passed to Pa_OpenStream() intended for storing synthesis data etc. @return The stream callback should return one of the values in the ::PaStreamCallbackResult enumeration. To ensure that the callback continues to be called, it should return paContinue (0). Either paComplete or paAbort can be returned to finish stream processing, after either of these values is returned the callback will not be called again. If paAbort is returned the stream will finish as soon as possible. If paComplete is returned, the stream will continue until all buffers generated by the callback have been played. This may be useful in applications such as soundfile players where a specific duration of output is required. However, it is not necessary to utilize this mechanism as Pa_StopStream(), Pa_AbortStream() or Pa_CloseStream() can also be used to stop the stream. The callback must always fill the entire output buffer irrespective of its return value. @see Pa_OpenStream, Pa_OpenDefaultStream @note With the exception of Pa_GetStreamCpuLoad() it is not permissible to call PortAudio API functions from within the stream callback. */ typedef int PaStreamCallback( const void *input, void *output, unsigned long frameCount, const PaStreamCallbackTimeInfo* timeInfo, PaStreamCallbackFlags statusFlags, void *userData ); /** Opens a stream for either input, output or both. @param stream The address of a PaStream pointer which will receive a pointer to the newly opened stream. @param inputParameters A structure that describes the input parameters used by the opened stream.
