OK guys, I really appriciate your funny answers about what signal processors are for. That wasn't really what I wanted to get. It seems as the whole world (except for someone at TEK whos name I've forgotten, has missunderstood my question (thanks a lot)). The problem is not what kind of device to use. The problem is the software, the maths behind. And the problem is not to make a real time FFT (thats not very hard). The problem is the get the Envelope of a sound's harmonics independent of its frequenzy. No more quick answers please.

Anyway, I have a program written in C that performs FFT's (Singletons Algorithm, Radix-2, DIT) It goes up to 8K (A memory limit). It is fairly optimized, but basically simulates a piece of hardware, so it's not generic. If you want it, let me know. I'll mail you the source. Failing that of course, you could build your own 20MHz real-time box in a week or two, right? - Der -- Reply: dtynan@sultra.UUCP (Der Tynan @ Tynan Computers) {mips,pyramid}!sultra!dtynan Cast a cold eye on life, on death.
