Thanks for your answer, it's much apreciated.
My goal is to resynthesize arbitary noises. If you do that with
wavetables you end up with a pitch of 20 Hz, hence the FFT.
My product idea was rubbish though and your post confirms that.
For your interest, I recently invented "noisetable

-Compress the peaks (without the surrounding regions) and noise into

(but how? - can you simply add those that fall into the same bins?)

I am curious about the spectrum compression part, would this work and
if not why not?
Ok, heres a final idea, can't test any of this so it's pure science fiction:
-Take a much larger FFT spectrogramme offline, with really fine overlap
granularity.
-Take the cesptrum, identify regions/groups of transients by new peaks
in the cepstrum.
-Pick peaks in the spectrum, by
