You should remember that automatic compression of arbitrary audio signals is
not likely to result in structured audio but AAC/TwinVQ in MPEG-4.

It is unlikely tat SA would be produced since the original data which is
compressed by these implementations rarely includes anything which could be
translated into SA sensibly. SA is the generative part of MPEG-4 audio so it
needs something like modular synthesis, tracker modules, MIDI files and the
related synthesis architecture they are meant to be played on or the output
of a dedicated, SA capable composing environment to produce. PCM audio
should be coded with the wide band coding toolkit, which is a separate part
of MPEG-4.
