Ha, found it... http://www.dspguide.com/ch12.htm
It is a while since I read this, but it hurt trying understand it a few times, then I got it, then I promptly forgot about it because I was using public domain code...

Someone asked me the other day, why the Sound class function computeSpectrum() returns specifically 512 floating point values. I know it returns 256 values for the left and right channels and that each value is a 32-bit floating point value of 4 bytes, but despite alot of Googling, I could find no explanation as to why it's 512 values (rather than 30 or 200,000). Maybe it's a audio specification, maybe it's a number the Adobe Flash team decided arbitrarily was sufficient to represend the sound frequencied. Does any one posses this knowledge?
