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:

We have an active mailing list for user and developer discussions. Please feel free to join. See http://www.portaudio.com for details.
