How to re-create a "ringmod sidechain" with look-ahead and attack?

Hello,

I would like to recreate "Kilohearts Compactor" for my patches.

Everything is pretty straight forward but i'm stuck with the look-ahead attack part.

I tried to delay the dry signal while adjusting delay for the attack (fade-in) portion of the side-chain,

but i can't find a good solution to fade-in the envelope; for exemple "Slide" attack don't respond to super short transient, like clicks.

How would you do that?

Thanks.

use two parallel analysis sections with for example different windows for the RMS or peak measurement, then you can choose between them and/or mix the results.

RMS of a click don't work too. I try to remake the pre-fade section. it work even on one sample compactor.

if you first feed the music signal through something like a [slide~ 0 4410] you can use that signal to further analyze and find even the shortest transient (and its maximum amplitude value) by splitting the signal based on delta values (up or down)

it will be still cheaper than upsampling x8 to see the power of a single spike or click in time...

okok i don't understand where it helps

Here is an exemple of what i'm trying to do.

Orange : SC source / Yellow: signal to duck / Green : result

See the pre fade-in ?

My brain is melting, help me. haha
