Are you saying it takes only 22cycles per sample (at 44khz) to decode a
vorbis track? (or .1% if you mean a 1ghz g4).  Some pcm software mixers
are only this fast (well it's a bit slow for a mixer but not unusual).
I find this hard to believe when the current reference decoder takes
about 20-30 times more cpu than that on my 1.2 ghz machine.
