It's not possiblme so far to extract pitch and timbre
information of seperate instruments out of a polyphonic
audio source. It's doable for a single monophonic voice
(there is some software that can do this pretty well). Beat
detection isn't all that easy either. Current beat
detection algorythms seem to do well on dance music and
related styles, but often fail on anything else.

Hi List.
Red Wizard Needs Help Badly. I'm looking for a sound Xtra
where I can
effectively extract a LOT of information from a song either
as it plays
or possibly even pre-process (provided I can get timing
information that
is usable). I'm looking for pitch, tone, beat, etc. not
just a 'start
and stop' control, but to know what notes, with what
voices, are active
at any given moment - from something like an MP3 or WAV
file.
Is this in any way doable or am I starting from scratch?
Thanks.
-A
