The - * host buffer size has to be one of these. - * - the number of periods that playback and/or capture support. - * - * We want to make period_size*(num_periods-1) to be as close as possible - * to latency*rate for both playback and capture. - * - * This method will determine suitable period sizes for capture and playback handles, and report the maximum number of - * frames per host buffer. The latter is relevant, in case we should be so unfortunate that the period size differs - * between capture and playback. If this should happen, the stream's hostBufferSizeMode attribute will be set to - * paUtilBoundedHostBufferSize, because the best we can do is limit the size of individual host buffers to the upper - * bound. The size of host buffers scheduled for processing should only matter if the user has specified a buffer size, - * but when he/she does we must strive for an optimal configuration. By default we'll opt for a fixed host buffer size, - * which should be fine if the period size is the same for capture and playback. In general, if there is a specified user - * buffer size, this method tries it best to determine a period size which is a multiple of the user buffer size. - * - * The framesPerPeriod attributes of the individual capture and playback components of the stream are set to corresponding - * values determined here. Since these should be reported as - * - * This is one of those blocks of code that will just take a lot of - * refinement to be any good. - * - * In the full-duplex case it is possible that the routine was unable - * to find a number of frames per buffer acceptable to both devices - * TODO: Implement an algorithm to find the value closest to acceptance - * by both devices, to minimize difference between period sizes? - * - * @param determinedFramesPerHostBuffer: The determined host buffer size. - */ -static PaError PaAlsaStream_DetermineFramesPerBuffer( PaAlsaStream* self, double sampleRate, const PaStreamParameters* inputParameters, - const PaStreamParameters* outputParameters, unsigned long framesPerUserBuffer, snd_pcm_hw_params_t* hwParamsCapture, - snd_pcm_hw_params_t* hwParamsPlayback, PaUtilHostBufferSizeMode* hostBufferSizeMode ) -{ - PaError result = paNoError;

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 - - <h3>Implementation strategy</h3> - - *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.

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.

To select use the old implementation, replace -pa_mac_core.c with pa_mac_core_old.c (eg. "cp pa_mac_core_auhal.c -pa_mac_core.c"), then run configure and make as usual. - -------------------------------------------- - -Notes on Newer/Default AUHAL implementation: - -by Bjorn Roche - -Last Updated December 9, 2005 - -Principle of Operation: - -This implementation uses AUHAL for audio I/O. To some extent, it also -operates at the "HAL" Layer, though this behavior can be limited by -platform specific flags (see pa_mac_core.h for details). The default -settings should be reasonable: they don't change the SR of the device and -don't cause interruptions if other devices are using the device. - -Major Software Elements Used: Apple's HAL AUs provide output SR -conversion transparently, however, only on output, so this -implementation uses AudioConverters to convert the sample rate on input. -A PortAudio ring buffer is used to buffer input when sample rate -conversion is required or when separate audio units are used for duplex -IO. Finally, a PortAudio buffer processor is used to convert formats and -provide additional buffers if needed. Internally, interleaved floating -point data streams are used exclusively - the audio unit converts from -the audio hardware's native format to interleaved float PCM and -PortAudio's Buffer processor is used for conversion to user formats. - -Simplex Input: Simplex input uses a single callback. If sample rate -conversion is required, a ring buffer and AudioConverter are used as -well. - -Simplex output: Simplex output uses a single callback. No ring buffer or -audio converter is used because AUHAL does its own output SR conversion. - -Duplex, one device (no SR conversion): When one device is used, a single -callback is used. This achieves very low latency. - -Duplex, separate devices or SR conversion: When SR conversion is -required, data must be buffered before it is converted and data is not -always available at the same times on input and output, so SR conversion -requires the same treatment as separate devices. The input callback -reads data and puts it in the ring buffer. The output callback reads the -data off the ring buffer, into an audio converter and finally to the -buffer processor. - -Platform Specific Options: - -By using the flags in pa_mac_core.h, the user may specify several options. -For example, the user can specify the sample-rate conversion quality, and -the extent to which PA will attempt to "play nice" and to what extent it -will interrupt other apps to improve performance. For example, if 44100 Hz -sample rate is requested but the device is set at 48000 Hz, PA can either -change the device for optimal playback ("Pro" mode), which may interrupt -other programs playing back audio, or simple use a sample-rate conversion, -which allows for friendlier sharing of the device ("Play Nice" mode). - -Additionally, the user may define a "channel mapping" by calling -paSetupMacCoreChannelMap() on their stream info structure before opening -the stream with it. See below for creating a channel map. - -Known issues: - -- Buffering: No buffering beyond that provided by core audio is provided -except where absolutely needed for the implementation to work. This may cause -issues with large framesPerBuffer settings and it also means that no additional -latency will be provided even if a large latency setting is selected. - -- Latency: Latency settings are generally ignored. They may be used as a -hint for buffer size in paHostFramesPerBufferUnspecified, or the value may -be used in cases where additional buffering is needed, such as doing input and -output on separate devices. Latency settings are always automatically bound -to "safe" values, however, so setting extreme values here should not be -an issue. - -- Buffer Size: paHostFramesPerBufferUnspecified and specific host buffer sizes -are supported. paHostFramesPerBufferUnspecified works best in "pro" mode, -where the buffer size and sample rate of the audio device is most likely -to match the expected values. In the case of paHostFramesPerBuffer, an -appropriate framesPerBuffer value will be used that guarantees minimum -requested latency if that's possible. - -- Timing info. It reports on stream time, but I'm probably doing something -wrong since patest_sine_time often reports negative latency numbers. Also, -there are currently issues with some devices whehn plugging/unplugging -devices. - -- xrun detection: The only xrun detection performed is when reading -and writing the ring buffer. There is probably more that can be done. - -- abort/stop issues: stopping a stream is always a complete operation, -but latency should be low enough to make the lack of a separate abort -unnecessary. Apple clarifies its AudioOutputUnitStop() call here: -http://lists.apple.com/archives/coreaudio-api/2005/Dec/msg00055.html - -- blocking interface: should work fine. - -- multichannel: It has been tested successfully on multichannel hardware -from MOTU: traveler and 896HD. Also Presonus firepod and others. It is -believed to work with all Core Audio devices, including virtual devices -such as soundflower. - -- sample rate conversion quality: By default, SR conversion is the maximum -available. This can be tweaked using flags pa_mac_core.h. Note that the AU -render quyality property is used to set the sample rate conversion quality -as "documented" here: -http://lists.apple.com/archives/coreaudio-api/2004/Jan/msg00141.html - -- x86/Universal Binary: Universal binaries can be build. - - - -Creating a channel map: - -How to create the map array - Text taken From AUHAL.rtfd : -[3] Channel Maps -Clients can tell the AUHAL units which channels of the device they are interested in. For example, the client may be processing stereo data, but outputting to a six-channel device. This is done by using the kAudioOutputUnitProperty_ChannelMap property. To use this property: - -For Output: -Create an array of SInt32 that is the size of the number of channels of the device (Get the Format of the AUHAL's output Element == 0) -Initialize each of the array's values to -1 (-1 indicates that that channel is NOT to be presented in the conversion.) - -Next, for each channel of your app's output, set: -channelMapArray[deviceOutputChannel] = desiredAppOutputChannel. - -For example: we have a 6 channel output device and our application has a stereo source it wants to provide to the device. Suppose we want that stereo source to go to the 3rd and 4th channels of the device. The channel map would look like this: { -1, -1, 0, 1, -1, -1 } - -Where the formats are: -Input Element == 0: 2 channels (- client format - settable) -Output Element == 0: 6 channels (- device format - NOT settable) - -So channel 2 (zero-based) of the device will take the first channel of output and channel 3 will take the second channel of output. (This translates to the 3rd and 4th plugs of the 6 output plugs of the device of course!) - -For Input: -Create an array of SInt32 that is the size of the number of channels of the format you require for input. Get (or Set in this case as needed) the AUHAL's output Element == 1. - -Next, for each channel of input you require, set: -channelMapArray[desiredAppInputChannel] = deviceOutputChannel; - -For example: we have a 6 channel input device from which we wish to receive stereo input from the 3rd and 4th channels. The channel map looks like this: { 2, 3 } - -Where the formats are: -Input Element == 0: 2 channels (- device format - NOT settable) -Output Element == 0: 6 channels (- client format - settable) - - - ----------------------------------------- - -Notes on Original implementation: - -by Phil Burk and Darren Gibbs - -Last updated March 20, 2002 - -WHAT WORKS - -Output with very low latency, <10 msec. -Half duplex input or output. -Full duplex on the same CoreAudio device. -The paFLoat32, paInt16, paInt8, paUInt8 sample formats. -Pa_GetCPULoad() -Pa_StreamTime() - -KNOWN BUGS OR LIMITATIONS - -We do not yet support simultaneous input and output on different -devices. Note that some CoreAudio devices like the Roland UH30 look -like one device but are actually two different CoreAudio devices. The -Built-In audio is typically one CoreAudio device. - -Mono doesn't work. - -DEVICE MAPPING - -CoreAudio devices can support both input and output. But the sample -rates supported may be different. So we have map one or two PortAudio -device to each CoreAudio device depending on whether it supports -input, output or both. - -When we query devices, we first get a list of CoreAudio devices. Then -we scan the list and add a PortAudio device for each CoreAudio device -that supports input. Then we make a scan for output devices. - diff --git a/portaudio/src/hostapi/coreaudio/pa_mac_core.c b/portaudio/src/hostapi/coreaudio/pa_mac_core.c deleted file mode 100644 index 26b814c..0000000 --- a/portaudio/src/hostapi/coreaudio/pa_mac_core.c +++ /dev/null @@ -1,2878 +0,0 @@ -/* - * Implementation of the PortAudio API for Apple AUHAL - * - * 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.

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 penalty 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). diff --git a/portaudio/src/hostapi/wmme/pa_win_wmme.c b/portaudio/src/hostapi/wmme/pa_win_wmme.c deleted file mode 100644 index f8b1d7e..0000000 --- a/portaudio/src/hostapi/wmme/pa_win_wmme.c +++ /dev/null @@ -1,4033 +0,0 @@ -/* - * $Id$ - * pa_win_wmme.c - * Implementation of PortAudio for Windows MultiMedia Extensions (WMME) - * - * PortAudio Portable Real-Time Audio Library - * Latest Version at: http://www.portaudio.com - * - * Authors: Ross Bencina and Phil Burk - * Copyright (c) 1999-2000 Ross Bencina and Phil Burk - * - * Permission is hereby granted, free of charge, to any person obtaining - * a copy of this software and associated documentation files - * (the "Software"), to deal in the Software without restriction, - * including without limitation the rights to use, copy, modify, merge, - * publish, distribute, sublicense, and/or sell copies of the Software, - * and to permit persons to whom the Software is furnished to do so, - * subject to the following conditions: - * - * The above copyright notice and this permission notice shall be - * included in all copies or substantial portions of the Software. - * - * 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 <stdio.h> -#include <stdlib.h> -#include <limits.h> -#include <math.h> -#include <windows.h> -#include <mmsystem.h> -#ifndef UNDER_CE -#include <process.h> -#endif -#include <assert.h> -/* PLB20010422 - "memory.h" doesn't work on CodeWarrior for PC.
