Nonlinear Space

TL;DW: Airwindows flexible reverb plugin.


There are many reverb plugins. This one is mine. And only this plugin has the power to turn Chris from Airwindows into a tumbling tiger. Fortunately my dexterity with these claws is almost unimpaired. I can still program, and I’ll have to, because they’ve broken all my guitar strings. And I’m not even going to get into what happened to the drumheads. Please join the Patreon and help me innovate new instruments to be played by large cats. I may be the first, but the rest of you will join me once you set the nonlinearity control to -11.

Nonlinear Space is special because it’s got filter controls and acoustic space simulation in the loops: the usual allpasses and comb filters are just a little different here, designed to produce a deeper sound that’ll blend into the mix better. It’s the peak (so far) of all my efforts with reverb, it has its own sound, and it’s free Mac/Windows/Linux AU/VST!

It’s also got a nonlinearity control, which besides the easter egg polymorph duties can do two things: one, it can make louder sounds sustain longer. This is a bit tricky to set up and you’ll want to feed it with consistent loudness, but you can get that ‘sort of 80s gated’ sound if you set it just right, especially if you’re driving it from just a snare track or something sparse like that. Two, it can make louder sounds sustain less, which is the opposite. Using it that way lets you set it up as a reverb bed which doesn’t die away, but you can replace the stuff in it by overlaying more sounds. It’s the opposite of the first nonlinearity but it might come in handy for ambient purposes.

The sample rate thing really just tells it what buffer lengths to use: shorter buffers make tighter spaces. It should give a roughly consistent sound if you use the buffer corresponding to your sample rate, but then you can also be at 44.1K and set it to 96K just to have a huge stadium soundscape. Half the fun here is using it inappropriately, so I wouldn’t dream of telling you how to use Nonlinear Space: I hope it’s easy to get normal sounds with, and for everything else, just have fun.

Until I think up even wilder algorithmic reverb ideas, enjoy Nonlinear Space. (and even then… because I think it will come in handy.)

This work is supported by my Patreon, and if it stays over $900 once April has begun, I really will give you Aura (the plugin, not the Hard Vacuum control) in April. And yeah… what really happened was, the video failed. I don’t know why, but I still had the demo and the mic recording, so happy April 1st :)
