Hello

I've been playing around with FFT a little bit, but I can't figure out a way to totally invert the spectra. I mean, I want the whole harmonic relationship to be inverted without changing every harmonic's intensity, but I want the low pitches changed to be high and viceversa.

I googled this: http://stackoverflow.com/questions/3520557/how-to-spectrum-inverse-a-sampled-audio-signal , but I wouldn't know how to do it in PD.

Any ideas?

Thanks.

wow man, you're amazing! it works perfectly!

I've already tried blockmirror~ but is not what I want 'cause it takes a block and reads the bins backwards. Maybe a graphic will explain better what I intend.

Anyway I really didn't thought something you wrote (toxonic), "but since fft converts the signal from the time domain into the frequency domain". I'll pay attention to that and try to figure out something.
