Vorbis decoder has already been ported to ARM. This is not public code, however.
But some recent stuff will allow us to write a portable integer-only encoder
and decoder reasonably soon.

One important issue: don't expect vorbis to be faster or more
cost-effective on
dsp than on a general purpose microprocessor.
