Advanced Max: FFTs, Part 2

Great tutorial. Looking forward to part 3 already. How could you store different fft frames, in a file or a matrix for later re-use?

@Graeme: yes, you can. For instance these tutorials (data written in a matrix), or in the Max examples, Extras -> Examples Overview -> MSP -> phase-vocoder-sampler (data written in a buffer~).

The windows in the fft-noise-reduction subpatch should have been squared to be correct. See also "MSP Analysis Tutorial 3: Using the FFT" in the Max Reference documentation.

^oh, i finally understand what Arthur above was trying to say: they meant "should have been passed through square-root..." (squared would be the opposite where it might be multiplied by itself, and i tried that also, but when they sum in 'overlap-add', it's not as ideal as when simply summing a straight Hanning window...) and i believe the "MSP Analysis Tutorial 3: Using the FFT" in the Max Reference documentation only did this because it starts with a 'triangle' window but Tim's way is probably more useful as something like a 'hanning' window is nicely summed with the overlap-add technique to remain at a constant of '1', especially where overlap is left at '2':

here's that patch:
