Does anyone know any nice compressor/dynamics abstractions that can run in vanilla pd?
I tried a search both here and and .info but nowt...
roman built a really nice one that is part of the net-pd collection, but i just checked and it seems to need zexy at least.
there might be a way to change it to make it work in vanilla though.
attached is my wrapped version of that patch
We need [808_state] ! 808_state $1/controls ... couldn't create Thx. ++

if i am not totally mistaken, the only critical (dsp wise) object used from zexy is [sgn~], which could be replaced with some [>=] trickery. all other zexy objects are only used for gui representation.
it's part of dynlib for netpd: http://www.netpd.org/dynlib
also frank posted a compressor a while ago on this list: http://lists.puredata.info/pipermail/pd-list/2008-10/065499.html

Excellent. Thanks to all.
I'm looking into learning how to implement compression by dissecting the patches so thanks a million for those.
Does anybody know if there's any theory about soft knees, program related releases, etc., so as to maybe emulate opto style compression or other types of esoteric compression?

Putting a low pass filter of a few Hz into the side chain can provide an attack. To soften the knee you need a smooth transfer function that multiplies the gain curve (so its a sort of second order thing). Places a curve between the linear 1:1 gain and reduced gain 1:n lines.
Opto is a feed forward style, and IIRC the photoresistor (ORP12 CdS2) has a slight persistence so it responds sluggishly to changes. I'm not sure if that's actually due to the slow cooling of a filament lamp some designs use one, but others use a LED which seems to be instant on/off)
Anyway, you could model feed-forward in Pd using a small delay buffer and a lowpass filter.
