It is currently a work in progress. Some command-line tools using these classes are in the AudioFileTools sample project.\\CAAudioFile has been reworked to optionally use the new ExtendedAudioFile API in Tiger. The functionality is essentially the same but a number of method names have been changed. To use the provided Panther-compatible implementation instead of requiring ExtendedAudioFile, define \f1\fs18 \cf2 \CocoaLigature0 CAAF_USE_EXTAUDIOFILE \f0\fs24 \cf0 \CocoaLigature1 to 1.\\The main classes are:\\CAAudioFile - wraps an AudioFile in an AudioConverter. The client specifies a PCM format to be used when reading/writing from the file, and the class performs any necessary decoding/encoding transparently. Be aware that most methods of this class may throw exceptions.\\CAAudioFileStreamer / CAAudioFileReader / CAAudioFileWriter - perfom asynchronous streaming of CAAudioFiles on a separate work thread for file I/O and decoding.These classes don't actually connect to the audio hardware.\\CAAudioFilePlayer / CAAudioFileRecorder - Subclasses of CAAudioFileReader / CAAudioFileWriter which use audio "output" (now I/O) units to actually play and recorder the audio.\\CAChannelMapper - uses the matrix mixer audio unit for converting (downmixing if necessary) between audio channel layouts.\\The other classes are support classes for the above.\}
