AFAIK MPEG4 files can contain these audio stream

- AAC
- TwinVQ
- CELP
- MP3 ( not in the original specs, but is in now )

More info here in this thread ( old ) :

I suggest to not name any of them as MPEG4 audio but give them strings of
their own. AAC would for sure be nice to have it supported by transors in an
early stage of the format, as there is right now no proper way of using it
in Ogg or AVI, only MP4, and only using DivX Networks MP4 muxing tools.
