-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 "tests/patest_saw.c" for an example.
-
-For information on compiling programs with PortAudio, please see the
-tutorial at:
-
- http://portaudio.com/trac/wiki/TutorialDir/TutorialStart
-
-
-Important Files and Folders:
- include/portaudio.h = header file for PortAudio API. Specifies API.
- src/common/ = platform independant code, host independant
- code for all implementations.
- src/os = os specific (but host api neutral) code
- src/hostapi = implementations for different host apis
-

-
-FILES:
-
-portaudio.h
- public api header file
-
-pa_front.c
- implements the interface defined in portaudio.h. manages multiple host apis.
- validates function parameters before calling through to host apis. tracks
- open streams and closes them at Pa_Terminate().
-
-pa_util.h
- declares utility functions for use my implementations. including utility
- functions which must be implemented separately for each platform.
-
-pa_hostapi.h
- hostapi representation structure used to interface between pa_front.c
- and implementations
-
-pa_stream.c/h
- stream interface and representation structures and helper functions
- used to interface between pa_front.c and implementations
-
-pa_cpuload.c/h
- source and header for cpu load calculation facility
-
-pa_trace.c/h
- source and header for debug trace log facility
-
-pa_converters.c/h
- sample buffer conversion facility
-
-pa_dither.c/h
- dither noise generator
-
-pa_process.c/h
- callback buffer processing facility including interleave and block adaption
-
-pa_allocation.c/h
- allocation context for tracking groups of allocations
-
-pa_skeleton.c
- an skeleton implementation showing how the common code can be used.
-
-pa_win_util.c
- Win32 implementation of platform specific PaUtil functions (memory allocation,
- usec clock, Pa_Sleep().) The file will be used with all Win32 host APIs.
-
-pa_win_hostapis.c
- contains the paHostApiInitializers array and an implementation of
- Pa_GetDefaultHostApi() for win32 builds.
-
-pa_win_wmme.c
- Win32 host api implementation for the windows multimedia extensions audio API.
-
-pa_win_wmme.h
- public header file containing interfaces to mme-specific functions and the
- deviceInfo data structure.
-
-
-CODING GUIDELINES:
-
-naming conventions:
- #defines begin with PA_
- #defines local to a file end with _
- global utility variables begin with paUtil
- global utility types begin with PaUtil (including function types)
- global utility functions begin with PaUtil_
- static variables end with _
- static constants begin with const and end with _
- static funtions have no special prefix/suffix
-
-In general, implementations should declare all of their members static,
-except for their initializer which should be exported. All exported names
-should be preceeded by Pa_ where MN is the module name, for example
-the windows mme initializer should be named PaWinWmme_Initialize().
-
-Every host api should define an initializer which returns an error code
-and a PaHostApiInterface*. The initializer should only return an error other
-than paNoError if it encounters an unexpected and fatal error (memory allocation
-error for example). In general, there may be conditions under which it returns
-a NULL interface pointer and also returns paNoError. For example, if the ASIO
-implementation detects that ASIO is not installed, it should return a
-NULL interface, and paNoError.
-
-Platform-specific shared functions should begin with Pa_ where PN is the
-platform name. eg. PaWin_ for windows, PaUnix_ for unix.
-
-The above two conventions should also be followed whenever it is necessary to
-share functions accross multiple source files.
-
-Two utilities for debug messages are provided. The PA_DEBUG macro defined in
-pa_implementation.h provides a simple way to print debug messages to stderr.
-Due to real-time performance issues, PA_DEBUG may not be suitable for use
-within the portaudio processing callback, or in other threads. In such cases
-the event tracing facility provided in pa_trace.h may be more appropriate.
-
-If PA_LOG_API_CALLS is defined, all calls to the public PortAudio API
-will be logged to stderr along with parameter and return values.
-
-
-TODO: (these need to be turned into TRAC items)
- write some new tests to exercise the multi-host-api functions
-
- write (doxygen) documentation for pa_trace (phil?)
-
- create a global configuration file which documents which PA_ defines can be
- used for configuration
-
- need a coding standard for comment formatting
-
- write style guide document (ross)

-Note: Because PortAudioCpp is now in the main PortAudio SVN repository, having these per-release changelogs probably doesn't make much sense anymore. 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.

- - 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.

-Installation Instructions
-*************************
-
-Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005 Free
-Software Foundation, Inc.
-
-This file is free documentation; the Free Software Foundation gives
-unlimited permission to copy, distribute and modify it.
-
-Basic Installation
-==================
-
-These are generic installation instructions.
-
- 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 only 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. If you're
- using `csh' on an old version of System V, you might need to type
- `sh ./configure' instead to prevent `csh' from trying to execute
- `configure' itself.
-
- Running `configure' takes awhile. 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.
-
- 4. Type `make install' to install the programs and any data files and
- documentation.
-
- 5. 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.
-
-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=c89 CFLAGS=-O2 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 must use a version of `make' that
-supports the `VPATH' variable, such as 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 `..'.
-
- If you have to use a `make' that does not support the `VPATH'
-variable, you have 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.
-
-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'.
-
- 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.
-
- 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'.
-
-Optional Features
-=================
-
-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.
-
-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). Here is a another example:
-
- /bin/bash ./configure CONFIG_SHELL=/bin/bash
-
-Here the `CONFIG_SHELL=/bin/bash' operand causes subsequent
-configuration-related scripts to be executed by `/bin/bash'.
-
-`configure' Invocation
-======================
-
-`configure' recognizes the following options to control how it operates.
-
-`--help'
-`-h'
- Print a summary of the options to `configure', and exit.
-
-`--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.
-
-`configure' also accepts some other, not widely useful, options. Run
-`configure --help' for more details.

-/// @mainpage PortAudioCpp
-///
-/// PortAudioCpp - A Native C++ Binding of PortAudio V19
-/// 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.
-///
-/// Links
-///
-/// Official PortAudio site.

-From: "Peter L Jones"
-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,
-

-Hello
-
- This is a small list of steps in order to build portaudio
-(Currently v19-devel) into a VC6 DLL and lib file.
-This DLL contains all 3 current win32 PA APIS (MM/DS/ASIO)
-
-1)Copy the source dirs that comes with the ASIO SDK inside src\hostapi\asio\ASIOSDK
- so you should now have example:
-
- portaudio19svn\src\hostapi\asio\ASIOSDK\common
- portaudio19svn\src\hostapi\asio\ASIOSDK\host
- portaudio19svn\src\hostapi\asio\ASIOSDK\host\sample
- portaudio19svn\src\hostapi\asio\ASIOSDK\host\pc
- portaudio19svn\src\hostapi\asio\ASIOSDK\host\mac (not needed)
-
- You dont need "driver"
-
-2)
- *If you have Visual Studio 6.0*, please make sure you have it updated with the latest (and final)
- microsoft libraries for it, namely:
-
- Service pack 5:
- Latest known URL:
- http://msdn2.microsoft.com/en-us/vstudio/aa718363.aspx
- Yes there EXISTS a service pack 6 , but the processor pack (below) isnt compatible with it.
-
- Processor Pack(only works with above SP5)
- Latest known URL:
- http://msdn2.microsoft.com/en-us/vstudio/Aa718349.aspx
- This isnt absolutely required for portaudio, but if you plan on using SSE intrinsics and similar things.
- Up to you to decide upon Service pack 5 or 6 depending on your need for intrinsics.
-
- Platform SDK (Feb 2003) :
- Latest known URL:
- http://www.microsoft.com/msdownload/platformsdk/sdkupdate/psdk-full.htm
- (This will allow your code base to be x64 friendly, with correct defines
- for LONG_PTR and such)
- NOTE A) Yes you have to use IE activex scripts to install that - wont work in Firefox, you
- may have to temporarily change tyour default browser(aint life unfair)
- NOTE B) Dont forget to hit "Register PSDK Directories with Visual Studio".
- you can make sure its right in VC6 if you open tools/options/directories/include files and you see SDK 2003 as the FIRST entry
- (it must be the same for libs)
-
- DirectX 9.0 SDK Update - (Summer 2003)
- Latest known URL:
- http://www.microsoft.com/downloads/details.aspx?familyid=9216652f-51e0-402e-b7b5-feb68d00f298&displaylang=en
- Again register the links in VC6, and check inside vc6 if headers are in second place right after SDk 2003
-
- *If you have 7.0(VC.NET/2001) or 7.1(VC.2003) *
- then I suggest you open portaudio.dsp (and convert if needed)
-
- *If you have Visual Studio 2005*, I suggest you open the portaudio.sln file
- which contains 4 configurations. Win32/x64 in both Release and Debug variants
-
- hit compile and hope for the best.
-
-3)Now in any project, in which you require portaudio,
- you can just link with portaudio_x86.lib, (or _x64) and of course include the
- relevant headers
- (portaudio.h, and/or pa_asio.h , pa_x86_plain_converters.h) See (*)
-
-4) Your new exe should now use portaudio_xXX.dll.
-
-
-Have fun!
-
-(*): you may want to add/remove some DLL entry points.
-Right now those 6 entries are _not_ from portaudio.h
-
-(from portaudio.def)
-(...)
-PaAsio_GetAvailableLatencyValues @50
-PaAsio_ShowControlPanel @51
-PaUtil_InitializeX86PlainConverters @52
-PaAsio_GetInputChannelName @53
-PaAsio_GetOutputChannelName @54
-PaUtil_SetLogPrintFunction @55

-
-PortAudio is an open-source cross-platform ‘C’ library for audio input
-and output. It is designed to simplify the porting of audio applications
-between various platforms, and also to simplify the development of audio
-software in general by hiding the complexities of device interfacing.
-
-See the PortAudio website for further information http://www.portaudio.com
-
-This documentation pertains to PortAudio V19, API version 2.0 which is
-currently under development. API version 2.0 differs in a number of ways from
-previous versions, please consult the enhancement proposals for further details:
-http://www.portaudio.com/docs/proposals/index.html
-
-This documentation is under construction. Things you might be interested in
-include:
-
-- The PortAudio API 2.0, as documented in portaudio.h
-
-- Tutorials for the V19 API, currently housed on the PortAudio Wiki:
-http://www.portaudio.com/trac/wiki/TutorialDir/TutorialStart
-
-- Implementation status is documented here:
-http://www.portaudio.com/docs/proposals/status.html
-
-- @ref srcguide
-
-- The @ref License
-
-
-If you're interested in contributing to PortAudio, you may be interested in:
-
-- The doxygen generated TODO List . Feel free to pick an item off TODO list
-and fix/implement it. You may want to enquire about status on the PortAudio mailing list first.

- @brief Allocation Group prototypes. An Allocation Group makes it easy to
- allocate multiple blocks of memory and free them all simultanously.
-
- An allocation group is useful for keeping track of multiple blocks
- of memory which are allocated at the same time (such as during initialization)
- and need to be deallocated at the same time. The allocation group maintains
- a list of allocated blocks, and can deallocate them all simultaneously which

-
- If the C9x function lrintf() is available, define PA_USE_C99_LRINTF to use it
-
- @todo Consider whether functions which dither but don't clip should exist,
- V18 automatically enabled clipping whenever dithering was selected. Perhaps
- we should do the same.
-
- @todo implement the converters marked IMPLEMENT ME: Float32_To_UInt8_Dither,

-/*Noise shaped dither (March 2000)
--------------------
-
-This is a simple implementation of highpass triangular-PDF dither with
-2nd-order noise shaping, for use when truncating floating point audio
-data to fixed point.
-
-The noise shaping lowers the noise floor by 11dB below 5kHz (@ 44100Hz
-sample rate) compared to triangular-PDF dither. The code below assumes
-input data is in the range +1 to -1 and doesn't check for overloads!
-
-To save time when generating dither for multiple channels you can do
-things like this: r3=(r1 & 0x7F)<<8; instead of calling rand() again.
-
-
-
- int r1, r2; //rectangular-PDF random numbers
- float s1, s2; //error feedback buffers

-16-to-8-bit first-order dither
-
-Type : First order error feedforward dithering code
-References : Posted by Jon Watte
-
-Notes :
-This is about as simple a dithering algorithm as you can implement, but it's
-likely to sound better than just truncating to N bits.
-
-Note that you might not want to carry forward the full difference for infinity.
-It's probably likely that the worst performance hit comes from the saturation
-conditionals, which can be avoided with appropriate instructions on many DSPs
-and integer SIMD type instructions, or CMOV.
-
-Last, if sound quality is paramount (such as when going from > 16 bits to 16
-bits) you probably want to use a higher-order dither function found elsewhere
-on this site.
-
-
-Code :
-// This code will down-convert and dither a 16-bit signed short
-// mono signal into an 8-bit unsigned char signal, using a first
-// order forward-feeding error term dither.
-
-#define uchar unsigned char
-
-void dither_one_channel_16_to_8( short * input, uchar * output, int count, int * memory )
-{
- int m = *memory;
- while( count-- > 0 ) {
- int i = *input++;
- i += m;
- int j = i + 32768 - 128;
- uchar o;
- if( j < 0 ) {
- o = 0;
- }
- else if( j > 65535 ) {
- o = 255;
- }
- else {
- o = (uchar)((j>>8)&0xff);
- }
- m = ((j-32768+128)-i);
- *output++ = o;
- }
- *memory = m;

- ValidateOpenStreamParameters() checks that parameters to Pa_OpenStream()
- conform to the expected values as described below. 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 200000.)
- - sampleRate is NOT validated against device capabilities
-

- - paNeverDropInput is only used for full-duplex callback streams with

-/** @file
- @ingroup common_src
-
- @brief Buffer Processor implementation.
-
- The code in this file is not optimised yet - although it's not clear that
- it needs to be. there may appear to be redundancies
- that could be factored into common functions, but the redundanceis are left
- intentionally as each appearance may have different optimisation possibilities.
-
- The optimisations which are planned involve only converting data in-place
- where possible, rather than copying to the temp buffer(s).
-
- Note that in the extreme case of being able to convert in-place, and there
- being no conversion necessary there should be some code which short-circuits
- the operation.
-
- @todo Consider cache tilings for intereave<->deinterleave.
-
- @todo implement timeInfo->currentTime int PaUtil_BeginBufferProcessing()
-
- @todo specify and implement some kind of logical policy for handling the
- underflow and overflow stream flags when the underflow/overflow overlaps
- multiple user buffers/callbacks.
-
- @todo provide support for priming the buffers with data from the callback.
- The client interface is now implemented through PaUtil_SetNoInput()
- which sets bp->hostInputChannels[0][0].data to zero. However this is
- currently only implemented in NonAdaptingProcess(). It shouldn't be
- needed for AdaptingInputOnlyProcess() (no priming should ever be
- requested for AdaptingInputOnlyProcess()).
- Not sure if additional work should be required to make it work with
- AdaptingOutputOnlyProcess, but it definitely is required for
- AdaptingProcess.
-
- @todo implement PaUtil_SetNoOutput for AdaptingProcess
-
- @todo don't allocate temp buffers for blocking streams unless they are
- needed. At the moment they are needed, but perhaps for host APIs
- where the implementation passes a buffer to the host they could be
- used.

-
- @brief Buffer Processor prototypes. A Buffer Processor performs buffer length
- adaption, coordinates sample format conversion, and interleaves/deinterleaves
- channels.
-
- 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.

-/* We need to determine how many frames per host buffer (period) to use. Our

- * - the period sizes that playback and/or capture support. The

- * We want to make period_size*(num_periods-1) to be as close as possible

- *
- * 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 framesPerBuffer attributes of the individual capture and playback components of the stream are set to corresponding

-/** @file
- @ingroup hostapi_src
- @brief Host API implementation supporting AudioScience cards
- via the Linux HPI interface.
-
- 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/spchpi.pdf
-
- 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.
-
- Please send bug reports etc. to Ludwig Schwardt

- It seems that the host API implementation has to keep track of the PortAudio stream state.

- these two concepts, a lot of flexibility is gained. There is a rough match between the two,
- of course, but forcing a precise match is difficult. For example, HPI_STATE_DRAINED can occur
- during the Active state of PortAudio (due to underruns) and also during CallBackFinished in
- the case of an output stream. Similarly, HPI_STATE_STOPPED mostly coincides with the Stopped
- PortAudio state, by may also occur in the CallbackFinished state when recording is finished.

-This document contains information to help you compile PortAudio with
-ASIO support. If you find any omissions or errors in this document
-please notify Ross Bencina .
-
-
-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 pa_common/ and platform specific files from pa_win/ (for Win32)
-or pa_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.net/en/ps/support/3rdparty/asio_sdk/
-
-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
-
-
-
-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 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;

- IASIOThiscallResolver.cpp see the comments in iasiothiscallresolver.h for
- the 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.
-
- Andrew Baldwin: contributed fixes for compatibility problems with more
- recent versions of the gcc assembler.

-// ****************************************************************************
-// File: IASIOThiscallResolver.h
-// Description: The IASIOThiscallResolver class implements the IASIO
-// interface and acts as a proxy to the real IASIO interface by
-// calling through its vptr table using the thiscall calling
-// convention. To put it another way, we interpose
-// IASIOThiscallResolver between ASIO SDK code and the driver.
-// This is necessary because most non-Microsoft compilers don't
-// implement the thiscall calling convention used by IASIO.
-//
-// iasiothiscallresolver.cpp contains the background of this
-// problem plus a technical description of the vptr
-// manipulations.
-//
-// In order to use this mechanism one simply has to add
-// iasiothiscallresolver.cpp to the list of files to compile
-// and #include
-//
-// 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

- 21-06-02 Added SelectHostBufferSize() which selects host buffer size based on user latency parameters : Ross Bencina
- ** NOTE maintanance history is now stored in CVS **
-*/
-
-/** @file
- @ingroup hostapi_src
-
- Note that specific support for paInputUnderflow, paOutputOverflow and
- paNeverDropInput is not necessary or possible with this driver due to the
- synchronous full duplex double-buffered architecture of ASIO.
-
- @todo check that CoInitialize()/CoUninitialize() are always correctly
- paired, even in error cases.
-
- @todo implement host api specific extension to set i/o buffer sizes in frames
-
- @todo implement ReadStream, WriteStream, GetStreamReadAvailable, GetStreamWriteAvailable
-
- @todo implement IsFormatSupported
-
- @todo work out how to implement stream stoppage from callback and
- implement IsStreamActive properly. Stream stoppage could be implemented
- using a high-priority thread blocked on an Event which is signalled
- by the callback. Or, we could just call ASIO stop from the callback
- and see what happens.
-
- @todo rigorously check asio return codes and convert to pa error codes
-
- @todo Different channels of a multichannel stream can have different sample
- formats, but we assume that all are the same as the first channel for now.
- Fixing this will require the block processor to maintain per-channel
- conversion functions - could get nasty.
-
- @todo investigate whether the asio processNow flag needs to be honoured
-
- @todo handle asioMessages() callbacks in a useful way, or at least document
- what cases we don't handle.
-
- @todo miscellaneous other FIXMEs
-
- @todo provide an asio-specific method for setting the systems specific
- value (aka main window handle) - check that this matches the value
- passed to PaAsio_ShowControlPanel, or remove it entirely from
- PaAsio_ShowControlPanel. - this would allow PaAsio_ShowControlPanel
- to be called for the currently open stream (at present all streams
- must be closed).

-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.

-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.

-/** @file
- @ingroup hostaip_src
-
- @todo implement paInputOverflow callback status flag
-
- @todo implement paNeverDropInput.
-
- @todo implement host api specific extension to set i/o buffer sizes in frames
-
- @todo implement initialisation of PaDeviceInfo default*Latency fields (currently set to 0.)
-
- @todo implement ReadStream, WriteStream, GetStreamReadAvailable, GetStreamWriteAvailable
-
- @todo audit handling of DirectSound result codes - in many cases we could convert a HRESULT into
- a native portaudio error code. Standard DirectSound result codes are documented at msdn.
-
- @todo implement IsFormatSupported
-
- @todo call PaUtil_SetLastHostErrorInfo with a specific error string (currently just "DSound error").
-
- @todo make sure all buffers have been played before stopping the stream
- when the stream callback returns paComplete
-
- @todo retrieve default devices using the DRVM_MAPPER_PREFERRED_GET functions used in the wmme api
- these wave device ids can be aligned with the directsound devices either by retrieving
- the system interface device name using DRV_QUERYDEVICEINTERFACE or by using the wave device
- id retrieved in KsPropertySetEnumerateCallback.
-
- old TODOs from phil, need to work out if these have been done:
- O- fix "patest_stop.c"

- FindDevicePnpInterfaces fills in the pnpInterface fields in deviceNamesAndGUIDs
- with UNICODE file paths to the devices. The DS documentation mentions
- at least two techniques by which these Interface paths can be found using IKsPropertySet on
- the DirectSound class object. One is using the DSPROPERTY_DIRECTSOUNDDEVICE_DESCRIPTION
- property, and the other is using DSPROPERTY_DIRECTSOUNDDEVICE_ENUMERATE.
- I tried both methods and only the second worked. I found two postings on the
- net from people who had the same problem with the first method, so I think the method used here is
- more common/likely to work. The probem is that IKsPropertySet_Get returns S_OK
- but the fields of the device description are not filled in.
-
- The mechanism we use works by registering an enumeration callback which is called for
- every DSound device. Our callback searches for a device in our deviceNamesAndGUIDs list
- with the matching GUID and copies the pointer to the Interface path.
- Note that we could have used this enumeration callback to perform the original
- device enumeration, however we choose not to so we can disable this step easily.
-
- Apparently the IKsPropertySet mechanism was added in DirectSound 9c 2004
