I don't know if you've solved your problem already, but I had the same one a little while ago and solved it by using libavcodec from the ffmpeg project to decompress MPEG 1/2 Audio Layer I/II elementary streams.

ffmpeg is under the LGPL, so the code also handles dynamic loading of the library from a dylib.

Also, I didn't really like the complexity of libavformat (the mux / demux library), thus I wrote simple framing routines as well.

Feel free to adapt the code to your needs.

Question to the CoreAudio team:

When will MPEG 1/2 Layer I/II audio decoding support make it into CoreAudio ?

Thanks.
