Attack & Release for Spectral Gate

Bertrand Fraysse's icon

Is there a way to change the attack and release of resynthesized bins in FFT.
For exemple : MSP Tutorial 26, in [p noise_gate]

In this case, if the amplitude of an fft bin is above a threshhold value, it is resynthesized. But is it possible to change the sine waves envelope... like in soundhack's +spectralgate or +spectralcompand plugin.

Yes, [vectral~] could do the trick but... I don't think I use it the way it should be used.
Look at my patch, maybe you know how to use it.
For the moment, it doesn't sound good.

A .rar file I don't know how to use.
Maybe you can send the patche(s) as text in the message, either Max4 or 5.

Ok I found it, [vectral~] was misplaced.

im confused as to why theres only 2 inputs for parameters yet theres 3 parameters, when I create the patch they are not connected and ive tried connecting them a few ways but they all seem incorrect as the release doesn't seem to have an effect and theres always some sort of grainy pops.

You send [pak slide 0 0] to the inlet going to [vectral] so you need 1 inlet for 2 parameters (attack & release).

In fact, the patch of my last post is not working, I did not deeply tried it. FFT is still strange to me, results are heavily varrying...
I tried my first patch again, and it was effectively doing the job. (but too high slide down values still sound strange)

By the way, the slide up is working nicely for a frequency related attack remover and a bit of slide down for a strange metallic reverb.
