FFT4 channels parameter

Let me ask a question.

Now Im trying to create FFT(N) channel module and
Im going to be modify FFT4 Channels module.

but I cant understand some parameter of this module.

Why this module separate 256 of spread nonuniformity?

thanks

hello, this is because humans have a logarithmic tone scale perception, but the FFT outputs 256 frequency bands in linear scale.
we have a hearing range from about 20 - 20.000 Hz, but the middle frequency range is at about 1000 Hz…

@tonfilm
ok.I understand!

Really thanks
