PortAudio is a free, cross-platform,open-source, audio I/O library. It lets you write simple audio programs in 'C' or C++ that will compile and run on many platforms including Windows, Macintosh OS X, and Unix (OSS/ALSA). It is intended to promote the exchange of audio software between developers on different platforms. Manyapplications use PortAudio for Audio I/O.
PortAudio provides a very simple API for recording and/or playing sound using a simple callback function or a blocking read/write interface. Example programs are included that play sine waves, process audio input (guitar fuzz), record and playback audio, list available audio devices, etc.
The PortaudioWiki is maintained by the community of PortAudio developers. It has the most up-to-date information and is recommended as a starting point for exploring PortAudio. PortAudio developers and users keep in touch on thePortAudio mailing list. Please feel free to join.
The PortAudio project and API was proposed byRoss Bencina to themusic-dsp mailing list. Ross uses PortAudio in hisAudioMulch synthesis application. Many people have sincecontributed to PortAudio's development.
This website is hosted and maintained by Phil Burk ofSoftSynth.com. Phil is also a co-designer of PortAudio and used it for audio I/O inJSyn, a real-time synthesis API for Java and 'C'.
