I've written classes in C++ and Objective-C for decompressing MPEG
files using mad (http://www.underbit.com/products/mad/). The C++ class
is available under a BSD license and is at
http://github.com/sbooth/SFBAudioEngine/blob/master/Decoders/MPEGDecoder.h
The read interface uses AudioBufferLists and shouldn't be too
difficult to hook up to a mixer.
