FFT Code I'm hammering out.

Day by day, line by line I increment ever
closer to the flute finger chart animation.
If you must know, I'm attempting to create
an animation where a flute player is shown
playing notes and as she plays the notes
the fingerings for each note she is playing
are sliding by.

to accomplish this I thought I'd harp on
some FFT code in an effort to kill multiple birds
with one projectile. (I've been wanting to pull
frequencies out of sound files for a while) I
just happen to have another idea in mind for the
same frequency pulling functionality.
