I need some help to make special use of the FFT.

I would like to separate my sound in, let’s say, 512 frequency band and be able to transpose each band independently.

I guess I have to use FFT. There’s a lot about filtering and convolution in the examples but nothing about transposition. Is it possible?

Thanks

]]>The sound sample in the patch in question is in the form of FFT Jitter matrix. And unfortunately you can’t record sound as FFT jitter matrix in that patch – I have that in a separate patch. Hence I am sending you also one already recorded FFT matrix, it should load automatically.

PS: In one week time, I will upload about 40 similar patches to the forum together with my dissertation. Stay tuned.

PS2: In the GRM version of Freq Warp I think there is also some (FFT?) filtering going on beside bin shifting.

In the dissertation I will post at the end of the week I explained everything in details. And first 80 pages is just FFT… I just need to make few corrections
