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. I run this command on Linux.
autoreconf -if
If you do not have autoreconf then do:
sudo apt-get install autoconf
If you get error like "possibly undefined macro: AC_LIBTOOL_WIN32_DLL"
then you try installing some more packages and then try again.
sudo apt-get install build-essential
sudo apt-get install pkg-config
sudo apt-get install libtool
autoreconf -if
Then test a build by doing:
./configure
make clean
make
then check in the related files that are modified.
These might include files like:
configure
config.guess
depcomp
install.sh

# PortAudio - portable audio I/O library
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 at http://www.portaudio.com/docs/
* Or at `/doc/html/index.html` after running Doxygen.
* Also see `src/common/portaudio.h` for the API spec.
* And see the `examples/` and `test/` directories for many examples of usage. (We suggest `examples/paex_saw.c` for an example.)
For information on compiling programs with PortAudio, please see the
tutorial at:
http://portaudio.com/docs/v19-doxydocs/tutorial_start.html
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 independent code, host independent
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
src/hostapi/asio = ASIO for Windows and Macintosh
src/hostapi/audioio = /dev/audio (Solaris/NetBSD Audio)
src/hostapi/coreaudio = Macintosh Core Audio for OS X
src/hostapi/dsound = Windows Direct Sound
src/hostapi/jack = JACK Audio Connection Kit
src/hostapi/oss = Unix Open Sound System (OSS)
src/hostapi/wasapi = Windows Vista WASAPI
src/hostapi/wdmks = Windows WDM Kernel Streaming
src/hostapi/wmme = Windows MultiMedia Extensions (MME)
### Test Programs:
test/pa_fuzz.c = guitar fuzz box
test/pa_devs.c = print a list of available devices
test/pa_minlat.c = determine minimum latency for your machine
test/paqa_devs.c = self test that opens all devices
test/paqa_errs.c = test error detection and reporting
test/patest_clip.c = hear a sine wave clipped and unclipped
test/patest_dither.c = hear effects of dithering (extremely subtle)
test/patest_pink.c = fun with pink noise
test/patest_record.c = record and playback some audio
test/patest_maxsines.c = how many sine waves can we play? Tests Pa_GetCPULoad().
test/patest_sine.c = output a sine wave in a simple PA app
test/patest_sync.c = test synchronization of audio and video
test/patest_wire.c = pass input to output, wire simulator

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 absence 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 preferred 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 statically 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 awkward 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 { ... }''.
PortAudioCpp v19 revision 05 03/04/09:

Installation Instructions

Basic Installation
==================
Briefly, the shell command `./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 10.6 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.
HP-UX `make' updates targets which have the same time stamps as
their prerequisites, which makes it generally unusable when shipped
generated files such as `configure' are involved. Use GNU `make'
instead.
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 limitation. Until the limitation is lifted, you can use
this workaround:
CONFIG_SHELL=/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.

#[=======================================================================[.rst:
FindASIO
--------
Finds the ASIO SDK by searching for the SDK ZIP in CMAKE_PREFIX_PATH and
CMAKE_CURRENT_BINARY_DIR. Alternatively, you may manually specify the path of
the SDK ZIP with the ASIO_SDK_ZIP_PATH variable, which can be used for caching
in CI scripts.
If the ZIP is found, this module extracts it.
The ZIP extraction is skipped if the unzipped SDK is found.
This module provides an `ASIO::host` IMPORT library target for building host
applications which use ASIO drivers. If you want to build an ASIO driver, this
module may serve as a useful start but you will need to modify it.

/// <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 explanation 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.

Finds the ASIO SDK by searching for the SDK ZIP in CMAKE_PREFIX_PATH and
CMAKE_CURRENT_BINARY_DIR. Alternatively, you may manually specify the path of
the SDK ZIP with the ASIO_SDK_ZIP_PATH variable, which can be used for caching
in CI scripts.
If the ZIP is found, this module extracts it.
The ZIP extraction is skipped if the unzipped SDK is found.
This module provides an `ASIO::host` IMPORT library target for building host
applications which use ASIO drivers. If you want to build an ASIO driver, this
module may serve as a useful start but you will need to modify it.
