35 PortAudio is a portable audio I/O library designed for cross-platform
36 support of audio. It uses a callback mechanism to request audio processing.
37 Audio can be generated in various formats, including 32 bit floating point,
38 and will be converted to the native format internally.
41 See "pa_common/portaudio.h" for API spec.
42 See docs folder for a tutorial.
43 Also see http://www.portaudio.com/docs/
44 And see "pa_tests/patest_saw.c" for an example.
46 For information on compiling programs with PortAudio, please see the
49 http://www.portaudio.com/docs/pa_tutorial.html
