PortAudio - Portable Audio Library

PortAudio is a cross platform audio I/O library proposed by Ross Bencina to the music-dsp mailing list. It provides a very simple API for recording and/or playing sound using a simple callback function. It is intended to promote the exchange of audio synthesis software between developers on different platforms. Example programs are included that synthesize sine waves and pink noise, perform fuzz distortion on a guitar, list available devices, etc.

This website is for implementations of the PortAudio library by Phil Burk of SoftSynth.com. Phil uses PortAudio as the basis for audio I/O in JSyn,.a real-time synthesis API for Java and 'C'.

For complete information, and for implementations on other platforms, please visit the PortAudio Home Page.
