cannam@124 41 PortAudio is a portable audio I/O library designed for cross-platform
cannam@124 42 support of audio. It uses either a callback mechanism to request audio
cannam@124 43 processing, or blocking read/write calls to buffer data between the
cannam@124 44 native audio subsystem and the client. Audio can be processed in various
cannam@124 45 formats, including 32 bit floating point, and will be converted to the
cannam@124 46 native format internally.
