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.
