I don't really keep track of that im affraid.. usually keep to else, cyclone and maybe brickwall is from audiolab? If i wasn't lazy i think all those tanh~ objects are in there for writing tables for the transfer functions.. im not so sure how precise or heavy they are to run so i usually stay clear of them.. it's very possible to change those for a mathematical equivalent/approximation. And the brickwall~ is just for anti aliasing when downsampling so you might use other filters for that.

I actually continued working on this for some time, specifically for guitar. I didn't really reach all the way i was hoping to, i found that it's hard to induce "shimmer" digitally... alas, i might upload the results during the week.

Ps. A big facepalm moment when i realized that my 'pseudo-integration' method is really just a naive lopass filter with a bunch of gain :,) so that saves a lot of cpu for V2 atleast..

Cheers
