PortAudio is a portable audio I/O library designed for cross-platform
|
||||
support of audio. It uses either a callback mechanism to request audio
|
||||
processing, or blocking read/write calls to buffer data between the
|
||||
native audio subsystem and the client. Audio can be processed in various
|
||||
formats, including 32 bit floating point, and will be converted to the
|
||||
native format internally.
|
||||
|
||||
Documentation:
|
||||
Documentation is available in "/doc/html/index.html"
|
||||
Also see "src/common/portaudio.h" for API spec.
|
||||
Also see http://www.portaudio.com/docs/
|
||||
And see the "test/" directory for many examples of usage
|
||||
(we suggest "test/patest_saw.c" for an example)
|
||||
|
||||

PortAudio is a portable audio I/O library designed for cross-platform
|
||||
support of audio. It uses either a callback mechanism to request audio
|
||||
processing, or blocking read/write calls to buffer data between the
|
||||
native audio subsystem and the client. Audio can be processed in various
|
||||
formats, including 32 bit floating point, and will be converted to the
|
||||
native format internally.
|
||||
|
||||
Documentation:
|
||||
Documentation is available in "/doc/html/index.html"
|
||||
Also see "src/common/portaudio.h" for API spec.
|
||||
Also see http://www.portaudio.com/docs/
|
||||
And see the "test/" directory for many examples of usage
|
||||
(we suggest "test/patest_saw.c" for an example)
|
||||

Sent: Wednesday, September 17, 2003 5:18 AM

||||
Subject: Dev-C++ project files
|
||||
|
||||
I attach two project files intended for portaudio/pa_win/dev-cpp (i.e. in
|
||||
parallel with the msvc directory), if you want them. One is for a static
|
||||
library build and one for a DLL. I've used the static library (in building
|
||||
a single monolithic DLL) but I can't guarantee the DLL version will build a
|
||||
working library (I think it's mostly there, though!).
|
||||
|
||||
I also attach the resulting makefiles, which may be of use to other MinGW
|
||||
users.
|
||||
|
||||
They're rooted in the directory given above and drop their object and
|
||||
library files in the same place. They assume the asiosdk2 files are in the
|
||||
same directory as portaudio/ in a sub-directory called asiosdk2/. Oh! The
|
||||
DLL is built against a static asiosdk2.a library... maybe not the best way
|
||||
to do it... I ought to figure out how to link against a "home made" dll in
|
||||
Dev-C++, I guess ;-)
|
||||
|
||||
Cheers,
|
||||

@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 C++, C#, Python, PureBasic, FreePascal and Lazarus.

|
||||
Read the @ref api_overview for a top-down view of the PortAudio API, its capabilities, functions and data structures. The documentation for PortAudio's main header file portaudio.h details the individual data types and functions that make up the API.

ASIO-README.txt
|
||||
|
||||
This document contains information to help you compile PortAudio with
|
||||
ASIO support. If you find any omissions or errors in this document
|
||||
please notify us on the PortAudio mailing list.
|
||||
|
||||
|
||||
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
|
||||
files from src/common/ and platform specific files from src/os/win/ (for Win32)
|
||||
or src/os/mac/ (for Macintosh).
|
||||
|
||||
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, possibly Mac), you may simply
|
||||
be able to type:
|
||||
|
||||
./configure --with-host_os=mingw --with-winapi=asio [--with-asiodir=/usr/local/asiosdk2]
|
||||
make
|
||||
|
||||
./configure --with-host_os=darwin --with-winapi=asio [--with-asiodir=/usr/local/asiosdk2]
|
||||
make
|
||||
|
||||
and life will be good.
|
||||
|
||||
|
||||
Obtaining the ASIO SDK
|
||||
----------------------
|
||||
|
||||
In order to build PortAudio with ASIO support, you need to download
|
||||
the ASIO SDK (version 2.0) 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.de/329+M52087573ab0.html
|
||||
|
||||
If the above link is broken search Google for:
|
||||
"download steinberg ASIO SDK"
|
||||
|
||||
|
||||
|
||||
Building the ASIO SDK on 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.
|
||||
|
||||
|
||||
|
||||
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.audiomulch.com/~rossb/code/calliasio
|
||||
|
||||

||||
|
||||
Macintosh ASIO SDK Bug Patch
|
||||
----------------------------
|
||||
|
||||
There is a bug in the ASIO SDK that causes the Macintosh version to
|
||||
often fail during initialization. Below is a patch that you can apply.
|
||||
|
||||
In codefragments.cpp replace getFrontProcessDirectory function with
|
||||
the following one (GetFrontProcess replaced by GetCurrentProcess).
|
||||
|
||||
|
||||
bool CodeFragments::getFrontProcessDirectory(void *specs)
|
||||
{
|
||||
FSSpec *fss = (FSSpec *)specs;
|
||||
ProcessInfoRec pif;
|
||||
ProcessSerialNumber psn;
|
||||
|
||||
memset(&psn,0,(long)sizeof(ProcessSerialNumber));
|
||||
// if(GetFrontProcess(&psn) == noErr) // wrong !!!
|
||||
if(GetCurrentProcess(&psn) == noErr) // correct !!!
|
||||
{
|
||||
pif.processName = 0;
|
||||
pif.processAppSpec = fss;
|
||||
pif.processInfoLength = sizeof(ProcessInfoRec);
|
||||
if(GetProcessInformation(&psn, &pif) == noErr)
|
||||
return true;
|
||||
}
|
||||
return false;
|
||||
}

and life will be good. Make sure you update the above with the correct local
|
||||
path to the ASIO SDK.

|
||||
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.
|
||||
|
||||

||||

||||
|
||||
|
||||
Building the ASIO SDK on (Pre-OS X) Macintosh
|
||||
---------------------------------------------
|
||||
|
||||
To build the ASIO SDK on Macintosh you need to compile and link with the
|
||||
following files from the ASIO SDK:
|
||||
|
||||
host/asiodrivers.cpp
|
||||
host/mac/asioshlib.cpp
|
||||
host/mac/codefragements.cpp
|
||||
|
||||
You may also need to adjust your include paths to support inclusion of
|
||||
header files from the above directories.
|
||||
|
||||
|
||||
|
||||
(Pre-OS X) Macintosh ASIO SDK Bug Patch
|
||||
---------------------------------------
|
||||
|
||||
There is a bug in the ASIO SDK that causes the Macintosh version to
|
||||
often fail during initialization. Below is a patch that you can apply.
|
||||
|
||||
In codefragments.cpp replace getFrontProcessDirectory function with
|
||||
the following one (GetFrontProcess replaced by GetCurrentProcess).
|
||||
|
||||
|
||||
bool CodeFragments::getFrontProcessDirectory(void *specs)
|
||||
{
|
||||
FSSpec *fss = (FSSpec *)specs;
|
||||
ProcessInfoRec pif;
|
||||
ProcessSerialNumber psn;
|
||||
|
||||
memset(&psn,0,(long)sizeof(ProcessSerialNumber));
|
||||
// if(GetFrontProcess(&psn) == noErr) // wrong !!!
|
||||
if(GetCurrentProcess(&psn) == noErr) // correct !!!
|
||||
{
|
||||
pif.processName = 0;
|
||||
pif.processAppSpec = fss;
|
||||
pif.processInfoLength = sizeof(ProcessInfoRec);
|
||||
if(GetProcessInformation(&psn, &pif) == noErr)
|
||||
return true;
|
||||
}
|
||||
return false;
|
||||
}

Notes on status of CoreAudio Implementation of PortAudio
|
||||
|
||||
Document Last Updated December 9, 2005
|
||||
|
||||
There are currently two implementations of PortAudio for Mac Core Audio.
|
||||
|
||||
The original is in pa_mac_core_old.c, and the newer, default implementation
|
||||
is in pa_mac_core.c.
|
||||
Only pa_mac_core.c is currently developed and supported as it uses apple's
|
||||
current core audio technology. To select use the old implementation, replace
|
||||
pa_mac_core.c with pa_mac_core_old.c (eg. "cp pa_mac_core_auhal.c
|
||||
pa_mac_core.c"), then run configure and make as usual.
|
||||
|
||||
-------------------------------------------
|
||||
|
||||
Notes on Newer/Default AUHAL implementation:
|
||||
|
||||
by Bjorn Roche
|
||||
|
||||
Last Updated December 9, 2005
|
||||
|
||||
Principle of Operation:
|
||||
|
||||
This implementation uses AUHAL for audio I/O. To some extent, it also
|
||||
operates at the "HAL" Layer, though this behavior can be limited by
|
||||
platform specific flags (see pa_mac_core.h for details). The default
|
||||
settings should be reasonable: they don't change the SR of the device and
|
||||
don't cause interruptions if other devices are using the device.
|
||||
|
||||
Major Software Elements Used: Apple's HAL AUs provide output SR
|
||||
conversion transparently, however, only on output, so this
|
||||
implementation uses AudioConverters to convert the sample rate on input.
|
||||
A PortAudio ring buffer is used to buffer input when sample rate
|
||||
conversion is required or when separate audio units are used for duplex
|
||||
IO. Finally, a PortAudio buffer processor is used to convert formats and
|
||||
provide additional buffers if needed. Internally, interleaved floating
|
||||
point data streams are used exclusively - the audio unit converts from
|
||||
the audio hardware's native format to interleaved float PCM and
|
||||
PortAudio's Buffer processor is used for conversion to user formats.
|
||||
|
||||
Simplex Input: Simplex input uses a single callback. If sample rate
|
||||
conversion is required, a ring buffer and AudioConverter are used as
|
||||
well.
|
||||
|
||||
Simplex output: Simplex output uses a single callback. No ring buffer or
|
||||
audio converter is used because AUHAL does its own output SR conversion.
|
||||
|
||||
Duplex, one device (no SR conversion): When one device is used, a single
|
||||
callback is used. This achieves very low latency.
|
||||
|
||||
Duplex, separate devices or SR conversion: When SR conversion is
|
||||
required, data must be buffered before it is converted and data is not
|
||||
always available at the same times on input and output, so SR conversion
|
||||
requires the same treatment as separate devices. The input callback
|
||||
reads data and puts it in the ring buffer. The output callback reads the
|
||||
data off the ring buffer, into an audio converter and finally to the
|
||||
buffer processor.
|
||||
|
||||
Platform Specific Options:
|
||||
|
||||
By using the flags in pa_mac_core.h, the user may specify several options.
|
||||
For example, the user can specify the sample-rate conversion quality, and
|
||||
the extent to which PA will attempt to "play nice" and to what extent it
|
||||
will interrupt other apps to improve performance. For example, if 44100 Hz
|
||||
sample rate is requested but the device is set at 48000 Hz, PA can either
|
||||
change the device for optimal playback ("Pro" mode), which may interrupt
|
||||
other programs playing back audio, or simple use a sample-rate 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)

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.

||||

||||
Notes on status of CoreAudio Implementation of PortAudio

|
||||
Document Last Updated December 9, 2005
|
||||
|
||||
There are currently two implementations of PortAudio for Mac Core Audio.
|
||||
|
||||
The original is in pa_mac_core_old.c, and the newer, default implementation
|
||||
is in pa_mac_core.c.
|
||||
Only pa_mac_core.c is currently developed and supported as it uses apple's
|
||||
current core audio technology. To select use the old implementation, replace
|
||||
pa_mac_core.c with pa_mac_core_old.c (eg. "cp pa_mac_core_auhal.c
|
||||
pa_mac_core.c"), then run configure and make as usual.

Notes on Newer/Default AUHAL implementation:
|
||||
|
||||
by Bjorn Roche
|
||||
|
||||
Last Updated December 9, 2005
|
||||
|
||||
Principle of Operation:
|
||||
|
||||
This implementation uses AUHAL for audio I/O. To some extent, it also
|
||||
operates at the "HAL" Layer, though this behavior can be limited by
|
||||
platform specific flags (see pa_mac_core.h for details). The default
|
||||
settings should be reasonable: they don't change the SR of the device and
|
||||
don't cause interruptions if other devices are using the device.
|
||||
|
||||
Major Software Elements Used: Apple's HAL AUs provide output SR
|
||||
conversion transparently, however, only on output, so this
|
||||
implementation uses AudioConverters to convert the sample rate on input.
|
||||
A PortAudio ring buffer is used to buffer input when sample rate
|
||||
conversion is required or when separate audio units are used for duplex
|
||||
IO. Finally, a PortAudio buffer processor is used to convert formats and
|
||||
provide additional buffers if needed. Internally, interleaved floating
|
||||
point data streams are used exclusively - the audio unit converts from
|
||||
the audio hardware's native format to interleaved float PCM and
|
||||
PortAudio's Buffer processor is used for conversion to user formats.
|
||||
|
||||
Simplex Input: Simplex input uses a single callback. If sample rate
|
||||
conversion is required, a ring buffer and AudioConverter are used as
|
||||
well.
|
||||
|
||||
Simplex output: Simplex output uses a single callback. No ring buffer or
|
||||
audio converter is used because AUHAL does its own output SR conversion.
|
||||
|
||||
Duplex, one device (no SR conversion): When one device is used, a single
|
||||
callback is used. This achieves very low latency.
|
||||
|
||||
Duplex, separate devices or SR conversion: When SR conversion is
|
||||
required, data must be buffered before it is converted and data is not
|
||||
always available at the same times on input and output, so SR conversion
|
||||
requires the same treatment as separate devices. The input callback
|
||||
reads data and puts it in the ring buffer. The output callback reads the
|
||||
data off the ring buffer, into an audio converter and finally to the
|
||||
buffer processor.
|
||||
|
||||
Platform Specific Options:
|
||||
|
||||
By using the flags in pa_mac_core.h, the user may specify several options.
|
||||
For example, the user can specify the sample-rate conversion quality, and
|
||||
the extent to which PA will attempt to "play nice" and to what extent it
|
||||
will interrupt other apps to improve performance. For example, if 44100 Hz
|
||||
sample rate is requested but the device is set at 48000 Hz, PA can either
|
||||
change the device for optimal playback ("Pro" mode), which may interrupt
|
||||
other programs playing back audio, or simple use a sample-rate 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.
|
||||

Notes about WDM-KS host API
|
||||
---------------------------
|
||||
|
||||
Status history
|
||||
--------------
|
||||
10th November 2005:
|
||||
Made following changes:
|
||||
* OpenStream: Try all PaSampleFormats internally if the the chosen
|
||||
format is not supported natively. This fixed several problems
|
||||
with soundcards that 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 undefine PA_NO_WDMKS from your build file,
|
||||
and include the pa_win_wdmks\pa_win_wdmks.c into your build.
|
||||
The file should compile in both C and C++.
|
||||
You will need a DirectX SDK installed on your system for the
|
||||
ks.h and ksmedia.h header files.
|
||||
You will need to link to the system "setupapi" library.
|
||||
Note that if you use MinGW, you will get more warnings from
|
||||
the DX header files when using GCC(C), and still a few warnings
