The GNU ccAudio2 package offers a highly portable C++ class framework
for developing applications which manipulate audio streams and various
disk based audio file formats. At the moment ccaudio is primarily a
class framework for handling .au, .wav (RIFF), and various .raw audio
encoding formats under Posix and win32 systems, though it may expand to
become a general purpose audio and soundcard support library. Support
for controlling CD audio devices has recently been added as well as
support for codecs and other generic audio processing services.
