fft dynamic eq?

seanzshow's icon

Hi, I am pretty new to using fft so not sure if this will work...

What I want to do is build an eq that will measure the frequency spectrum of one sound and inversely apply the envelope to the spectrum of another sound.

Similiar to multi-band compression, but actually using an eq that is side-chained from another sound source.

Like I said, im still getting to grips with the fft object so not sure if this is the best way to approach the problem.

Any help would be great.

Cheers

Sounds like convolution, yes? There are some examples in the examples folder.

it is possible with the simple FFT filter of the examples.

the most straight forward way would be this:

to apply the timbre from A to B you must analyze
BOTH to get the difference, then apply the difference
setting * -1. to A.
