Please copy me on your summary.  I have some FFT code that I FTP'd from
a server in UK.  It was originally written by someone in New Mexico, I
believe.  
[now known to be Richard Krukar who doesn't appear to be in 
New Mexico anymore].  
It precalculates coeffecients for up to the 512 sample size
case.  It's floating point, so I'd imagine it's not a real screamer.

I could use the world's fastest FFT (not yet sure what I'd do with it, 
but spectrum analysis of sampled sound would keep me busy for awhile), 
so I you get a better source, I would appreciate it.

If you don't already have the FFT code to which I've referred, let me
know and I'll send it off to you (let me know preferred formats and
I'll try to accomodate).  Hope I can help and thanks.

Regards
 -Tom
