PortAudio is a free, cross-platform, open-source, audio I/O library. It lets you write simple audio programs in 'C' or C++ that will compile and run on many platforms including Windows, Macintosh OS X, and Unix (OSS/ALSA). It is intended to promote the exchange of audio software between developers on different platforms. Many applications use PortAudio for Audio I/O.
PortAudio provides a very simple API for recording and/or playing sound using a simple callback function or a blocking read/write interface. Example programs are included that play sine waves, process audio input (guitar fuzz), record and playback audio, list
Its hard to believe that there aren't a million recommendations on such a brilliant library! I love PortAudio! Thanks rossb!
