PortAudio uses "autoconf" tools to generate Makefiles for Linux and Mac platforms.
The source for these are configure.in and Makefile.in
If you modify either of these files then please run this command before
testing and checking in your changes.
autoreconf -if
Then test a build by doing:
./configure
make clean
make
sudo make install
then check in the related files that are modified.
These might include files like:
configure
config.guess
depcomp
install.sh

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)
For information on compiling programs with PortAudio, please see the
tutorial at:
http://portaudio.com/trac/wiki/TutorialDir/TutorialStart
We have an active mailing list for user and developer discussions.
Please feel free to join. See http://www.portaudio.com for details.
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
Host API Implementations:
src/hostapi/alsa = Advanced Linux Sound Architecture (ALSA)
src/hostapi/asihpi = AudioScience HPI

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.
- Renamed ``Latency'' to ``BufferSize'' in AsioDeviceAdapter.
- Updated class documentation.
PortAudioCpp v19 revision 10 03/07/18:
mblaauw:
- SingleDirectionStreamParameters now has a (static) null() method.
- StreamParameters uses references for the direction-specific stream parameters
instead of pointers (use null() method (above) instead of NULL).
- StreamParameters and SingleDirectionStreamParameters must now be fully specified
and now default values are used (because this was not very useful in general and
only made things more complex).
- Updated documentation.
PortAudioCpp v19 revision 09 03/06/25:
mblaauw:
- Changed some things in SingleDirectionStreamParameters to ease it's usage.
- Placed all SingleDirectionStreamParameters stuff into a separate file.
+ Totally redid the callback stuff, now it's less ackward and supports C++ functions.
PortAudioCpp v19 revision 08 03/06/20:
mblaauw:
- Made deconstructors for Device and HostApi private.
+ Added a AsioDeviceWrapper host api specific device extension class.
- Refactored Exception into a Exception base class and PaException and PaCppException
derived classes.
- Added ASIO specific device info to the devs.cxx example.
- Fixed a bug in System::hostApiCount() and System::defaultHostApi().
+ Moved Device::null to System::nullDevice.
- Fixed some bugs in Device and System.
PortAudioCpp v19 revision 07 03/06/08:
mblaauw:
- Updated some doxy comments.
+ Renamed CbXyz to CallbackXyz.
+ Renamed all ``configurations'' to ``parameters''.
+ Renamed HalfDuplexStreamConfiguration to SingleDirectionStreamConfiguration.
- Renamed SingleDirectionStreamParameters::streamParameters() to
SingleDirectionStreamParameters::paSteamParameters.
- Added a non-constant version of SingleDirectionStreamParameters::paStreamParameters().
- A few improvements to SingleDirectionStreamParameters.
- Allowed AutoSystem to be created without initializing the System singleton
(using a ctor flag).
- Added a BlockingStream class (not implemented for now).
- Fixed many bugs in the implementation of the iterators.
- Fixed a bug in Device::operator==().
+ Added a C++ version of the patest_sine.c test/example.
- Added a ctor for StreamParameters for a default half-duplex stream.
- Added SingleDirectionStreamParameters::setDevice() and setNumChannels().
- Renamed System::numHostApis() to System::hostApiCount().
+ Rewrote the iterators and related classes. They are now fully STL compliant. The System now
has a static array of all HostApis and all Devices. Only the System can create HostApis and
Devices and they are non-copyable now. All HostApis and Devices are now passed by-reference.
- Renamed (System::) getVersion() to version() and getVersionText() to versionText().
- Renamed (Device::) numXyzChannels() to maxXyzChannels().
- Changed some stuff in StreamParameters.
+ Added a C++ version of the patest_devs.c test/example.
PortAudioCpp v19 revision 06 03/06/04:
mblaauw:
+ Added this file to the project (roughly, a `+' denotes a major change, a `-' a minor change).
- Added System::deviceByIndex(), useful when a Device's index is stored for instance.
- Renamed System::hostApiFromTypeId() to System::hostApiByTypeId().
- Updated and added some Doxygen documentation.
- Made Stream::usedIntputLatency(), Stream::usedOutputLatency() and
Stream::usedSampleRate() throw an paInternalError equivalent exception instead of paBadStreamPtr.
- Changed exception handling in Stream::open() functions. They now follow the PA error handling
mechanism better and a couple of bugs regarding ownership of objects were fixed.
- Renamed Device::isDefaultXyzDevice() to Device::isSystemDefaultXyzDevice().
- Added Device::isHostApiDefaultXyzDevice().
- Added StreamConfiguration::unsetFlag().
- Removed CUSTOM from SampleDataFormat.
- System::hostApiByTypeId() now throws an paInternalError if the type id was out-of-range; this
is a temporary work-around (see comments).
- Changed CbInterface to use paCallbackFun() instead of operator()().
- Renamed ``object'' to ``instance'' in CbMemFunAdapter.hxx.
- Added StreamConfiguration::setXyzHostApiSpecificSampleFormat().
- Added StreamConfiguration::isXyzSampleFormatHostApiSpecific().
- Changed error handling in System::terminate(), it can now throw an Exception.
- Added error handling in System::defaultHostApi().
- Added error handling in System::hostApisEnd().
- Changed some (but probably not all) C casts to C++ casts to avoid confusion with a
certain Python person.
- Renamed RaiiSystem to AutoSystem (class and file) as this is a come common convention.
- Renamed System::numDevices() to System::deviceCount() to be more compatible with PortAudio
(although PortAudio uses Pa_CountDevices() instead, see comment).
- Renamed HostApi::numDevices() to HostApi::deviceCount().
- Changed INC_ to INCLUDED_ in the header multiple include guards.
- Changed the order of functions in the StreamConfiguration class' header.
- Written some more info in PortAudioCpp.hxx (Doxygen).
- Added CallbackStream.hxx and CallbackStream.cxx files.
+ Refactored StreamConfiguration to remove the duplication which was there. There is now a
HalfDuplexStreamConfiguration class. Also made some improvements to these classes while
doing the refactoring.
+ Moved all code files to source/portaudiocpp/ and changed includes.
+ Moved all header files to include/portaudiocpp/ to easy a binary build if needed. The project
must be set to have .../include/ as a path to look for includes.
+ Refactored the Stream class into a Stream base class and a CallbackStream derived class.
- Renamed Stream::usingXyz() to Stream::xyz().
- Updated some doxy comments.
- Changed ``using namespace portaudio'' in .cxx files to ``namespace portaudio { ... }''.

Installation Instructions
*************************
Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
2006, 2007, 2008, 2009 Free Software Foundation, Inc.
Copying and distribution of this file, with or without modification,
are permitted in any medium without royalty provided the copyright
notice and this notice are preserved. This file is offered as-is,
without warranty of any kind.
Basic Installation
==================
Briefly, the shell commands `./configure; make; make install' should
configure, build, and install this package. The following
more-detailed instructions are generic; see the `README' file for
instructions specific to this package. Some packages provide this
`INSTALL' file but do not implement all of the features documented
below. The lack of an optional feature in a given package is not
necessarily a bug. More recommendations for GNU packages can be found
in *note Makefile Conventions: (standards)Makefile Conventions.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').
It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring. Caching is
disabled by default to prevent problems with accidental use of stale
cache files.
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.
The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'. You need `configure.ac' if
you want to change it or regenerate `configure' using a newer version
of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system.
Running `configure' might take a while. While running, it prints
some messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package, generally using the just-built uninstalled binaries.
4. Type `make install' to install the programs and any data files and
documentation. When installing into a prefix owned by root, it is
recommended that the package be configured and built as a regular
user, and only the `make install' phase executed with root
privileges.
5. Optionally, type `make installcheck' to repeat any self-tests, but
this time using the binaries in their final installed location.
This target does not install anything. Running this target as a
regular user, particularly if the prior `make install' required
root privileges, verifies that the installation completed
correctly.
6. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
7. Often, you can also type `make uninstall' to remove the installed
files again. In practice, not all packages have tested that
uninstallation works correctly, even though it is required by the
GNU Coding Standards.
8. Some packages, particularly those that use Automake, provide `make
distcheck', which can by used by developers to test that all other
targets like `make install' and `make uninstall' work correctly.
This target is generally not run by end users.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that
the `configure' script does not know about. Run `./configure --help'
for details on some of the pertinent environment variables.
You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here
is an example:
./configure CC=c99 CFLAGS=-g LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you can use GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'. This
is known as a "VPATH" build.
With a non-GNU `make', it is safer to compile the package for one
architecture at a time in the source code directory. After you have
installed the package for one architecture, use `make distclean' before
reconfiguring for another architecture.
On MacOS X 10.5 and later systems, you can create libraries and
executables that work on multiple system types--known as "fat" or
"universal" binaries--by specifying multiple `-arch' options to the
compiler but only a single `-arch' option to the preprocessor. Like
this:
./configure CC="gcc -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
CXX="g++ -arch i386 -arch x86_64 -arch ppc -arch ppc64" \
CPP="gcc -E" CXXCPP="g++ -E"
This is not guaranteed to produce working output in all cases, you
may have to build one architecture at a time and combine the results
using the `lipo' tool if you have problems.
Installation Names
==================
By default, `make install' installs the package's commands under
`/usr/local/bin', include files under `/usr/local/include', etc. You
can specify an installation prefix other than `/usr/local' by giving
`configure' the option `--prefix=PREFIX', where PREFIX must be an
absolute file name.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
pass the option `--exec-prefix=PREFIX' to `configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=DIR' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them. In general, the
default for these options is expressed in terms of `${prefix}', so that
specifying just `--prefix' will affect all of the other directory
specifications that were not explicitly provided.
The most portable way to affect installation locations is to pass the
correct locations to `configure'; however, many packages provide one or
both of the following shortcuts of passing variable assignments to the
`make install' command line to change installation locations without
having to reconfigure or recompile.
The first method involves providing an override variable for each
affected directory. For example, `make install
prefix=/alternate/directory' will choose an alternate location for all
directory configuration variables that were expressed in terms of
`${prefix}'. Any directories that were specified during `configure',
but not in terms of `${prefix}', must each be overridden at install
time for the entire installation to be relocated. The approach of
makefile variable overrides for each directory variable is required by
the GNU Coding Standards, and ideally causes no recompilation.
However, some platforms have known limitations with the semantics of
shared libraries that end up requiring recompilation when using this
method, particularly noticeable in packages that use GNU Libtool.
The second method involves providing the `DESTDIR' variable. For
example, `make install DESTDIR=/alternate/directory' will prepend
`/alternate/directory' before all installation names. The approach of
`DESTDIR' overrides is not required by the GNU Coding Standards, and
does not work on platforms that have drive letters. On the other hand,
it does better at avoiding recompilation issues, and works well even
when some directory options were not specified in terms of `${prefix}'
at `configure' time.
Optional Features
=================
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Some packages offer the ability to configure how verbose the
execution of `make' will be. For these packages, running `./configure
--enable-silent-rules' sets the default to minimal output, which can be
overridden with `make V=1'; while running `./configure
--disable-silent-rules' sets the default to verbose, which can be
overridden with `make V=0'.
Particular systems
==================
On HP-UX, the default C compiler is not ANSI C compatible. If GNU
CC is not installed, it is recommended to use the following options in
order to use an ANSI C compiler:
./configure CC="cc -Ae -D_XOPEN_SOURCE=500"
and if that doesn't work, install pre-built binaries of GCC for HP-UX.
On OSF/1 a.k.a. Tru64, some versions of the default C compiler cannot
parse its `<wchar.h>' header file. The option `-nodtk' can be used as
a workaround. If GNU CC is not installed, it is therefore recommended
to try
./configure CC="cc"
and if that doesn't work, try
./configure CC="cc -nodtk"
On Solaris, don't put `/usr/ucb' early in your `PATH'. This
directory contains several dysfunctional programs; working variants of
these programs are available in `/usr/bin'. So, if you need `/usr/ucb'
in your `PATH', put it _after_ `/usr/bin'.
On Haiku, software installed for all users goes in `/boot/common',
not `/usr/local'. It is recommended to use the following options:
./configure --prefix=/boot/common
Specifying the System Type
==========================
There may be some features `configure' cannot figure out
automatically, but needs to determine by the type of machine the package
will run on. Usually, assuming the package is built to be run on the
_same_ architectures, `configure' can figure that out, but if it prints
a message saying it cannot guess the machine type, give it the
`--build=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS
KERNEL-OS
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the option `--target=TYPE' to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share,
you can create a site shell script called `config.site' that gives
default values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Defining Variables
==================
Variables not defined in a site shell script can be set in the
environment passed to `configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
causes the specified `gcc' to be used as the C compiler (unless it is
overridden in the site shell script).
Unfortunately, this technique does not work for `CONFIG_SHELL' due to
an Autoconf bug. Until the bug is fixed you can use this workaround:
CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
`configure' Invocation
======================
`configure' recognizes the following options to control how it
operates.
`--help'
`-h'
Print a summary of all of the options to `configure', and exit.
`--help=short'
`--help=recursive'
Print a summary of the options unique to this package's
`configure', and exit. The `short' variant lists options used
only in the top level, while the `recursive' variant lists options
also present in any nested packages.
`--version'
`-V'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally `config.cache'. FILE defaults to `/dev/null' to
disable caching.
`--config-cache'
`-C'
Alias for `--cache-file=config.cache'.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`--prefix=DIR'
Use DIR as the installation prefix. *note Installation Names::
for more details, including other options available for fine-tuning
the installation locations.
`--no-create'
`-n'
Run the configure checks, but stop before creating any output
files.
`configure' also accepts some other, not widely useful, options. Run
`configure --help' for more details.

/// <h1>PortAudioCpp - A Native C++ Binding of PortAudio V19</h1>
/// <h2>PortAudio</h2>
/// <p>
/// 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.
/// </p>
/// <h2>PortAudioCpp</h2>
/// <p>
/// 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'.
/// </p>
/// <p>
/// PortAudioCpp's main features are:
/// <ul>
/// <li>Structured object model.</li>
/// <li>C++ exception handling instead of C-style error return codes.</li>
/// <li>Handling of callbacks using free functions (C and C++), static functions, member functions or instances of classes
/// derived from a given interface.</li>
/// <li>STL compliant iterators to host APIs and devices.</li>
/// <li>Some additional convenience functions to more easily set up and use PortAudio.</li>
/// </ul>
/// </p>
/// <p>
/// 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.
/// </p>
/// <p>
/// Supported platforms:
/// <ul>
/// <li>Microsoft Visual C++ 6.0, 7.0 (.NET 2002) and 7.1 (.NET 2003).</li>
/// <li>GNU G++ 2.95 and G++ 3.3.</li>
/// </ul>
/// Other platforms should be easily supported as PortAudioCpp is platform-independent and (reasonably) C++ standard compliant.
/// </p>
/// <p>
/// This documentation mainly provides information specific to PortAudioCpp. For a more complete explaination of all of the
/// concepts used, please consult the PortAudio documentation.
/// </p>
/// <p>
/// 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 <a href="http://www.portaudio.com/license.html">the PortAudio license</a> for more details.

preprocessor options, MSVC f.i. has no way of knowing when an option (or var) changes as there is no dependency chain.
The generated "options_cmake.h" should be included like so:
#ifdef PORTAUDIO_CMAKE_GENERATED

so that non-CMake build environments are left intact.

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

/** @mainpage
@section overview Overview
PortAudio is a cross-platform, open-source C language library for real-time audio input and output. The library provides functions that allow your software to acquire and output real-time audio streams from your computer's hardware audio interfaces. It is designed to simplify writing cross-platform audio applications, and also to simplify the development of audio software in general by hiding the complexities of dealing directly with each native audio API. PortAudio is used to implement sound recording, editing and mixing applications, software synthesizers, effects processors, music players, internet telephony applications, software defined radios and more. Supported platforms include MS Windows, Mac OS X and Linux. Third-party language bindings make it possible to call PortAudio from other programming languages including C++, C#, Python, PureBasic, FreePascal and Lazarus.
