fft question

Post by leondustar »

hi, first of all thx for FFT.

1. in theory, for a 2048 FFt window, can I achieve a dry/wet-mix without using an extra FFT for the dry signal? I tried using a delay of 2048 samples for the dry signal but it seems not enough (flanging sound)

2. what does the deform2 param do with the fft bins exactly?
Is the value (lets assume 0..1) just interpolating each bin's original level (0) until the maximum bin level (1)?

Your theory is correct, but only if the sample rate of FFT is the same as the SunVox sample rate (in Preferences -> Audio)

Yes, your description is very close to the deform2 algorithm :)
