41 PortAudio is a portable audio I/O library designed for cross-platform
|
|
Chris@39
|
42 support of audio. It uses either a callback mechanism to request audio
|
|
Chris@39
|
43 processing, or blocking read/write calls to buffer data between the
|
|
Chris@39
|
44 native audio subsystem and the client. Audio can be processed in various
|
|
Chris@39
|
45 formats, including 32 bit floating point, and will be converted to the
|
|
Chris@39
|
46 native format internally.
