Airwindows is one guy: me! I am an audio hacker and computer programmer from way back. I seek only to continue my life up here in Vermont, inventing things and putting them onto the internet, sometimes for free and sometimes for pay. My hope is that people richer than me (i.e. most people) don't rob me. My other hope is for another cup of Aeropress. One out of two ain't bad!



NonlinearSpaceDemo is a universal binary Audio Unit plugin for algorithmic reverb. It extends on what its predecessor Space offered, by adding Nonlin behavior in two ways! You’ve got a Sample Rate control that sets the overall size of the reverb tank. This isn’t meant to be switched while the reverb is live, so if there’s […]


MineSpace is something a bit out of the ordinary: a game ambiance reverb for Let’s Plays. It came about because I did some Minecraft Let’s Plays, and was interested in applying reverb in giant caves and such. However, normal reverbs tended to be far too strong, and stereo reverb didn’t match well with the twisting, turning […]


SpaceDemo is the latest Airwindows algorithmic reverb, set up to work like the first hardware digital reverbs, and giving more spatial depth than typical digital reverbs. It decays in a special way, like acoustic space, and has bass and treble controls that help you fit it into the mix, and liveness can be cranked up until […]


PocketVerbsDemo is a universal binary Audio Unit plugin (64/32/PPC) for specialty reverbs! It offers a variety of verb types, both normal and strange, and permits gating and dynamic reverb levels based on signal intensity. Dual mono for bigger mix width! This isn’t the ‘normal’ Airwindows reverb. That’s been developed over the years, through products like FarSpace, […]


FarSpace3Demo is a precursor to Space, and the last in a series of reverb experiments that started from the very basics (a cluster of simple delays, the freebie Verbs). It has two separate ways to manage verb size, the Room Size and the Liveness controls. Brightness is NOT an overall EQ on the reverb’s output, like […]


AllSpaceDemo is like a precursor to PocketVerbs, only not :) Specifically, this is the reverb designed to run dual-mono and give the ultimate, hugest, lushest depth. It’s also the reverb that put the hurt on processors back in the day, and broke Digital Performer while it was at it. Still don’t know what went wrong there, […]

Fireworks Reverbs

FireworksReverbs is a newer set of reverb impulses for convolution reverbs. Contains a lot of really killer sound design and special effect impulses! This is zipped AIFF files, so it is usable on a PC if you can read AIFFs. If you’d like to install them in Logic as presets (Mac only, uses installer), thank Mini-Dan […]


FarSpace2Demo was the second incarnation of FarSpace/NearSpace. Changes involved simplifying the processing, removing the antialiasing which was there to handle the anti-saturation code that got removed. During this period FarSpace changed its sound around pretty wildly while not being awesome. I’m going to encourage paying attention to reverbs like Space, PocketVerbs, and even FarSpace3, but this […]


FarSpace began the series of reverbs culminating in Space (a long sequence of free upgrades and crossgrades for adopters this early!). It contained NearSpace, a matching reverb hard-coded to have shorter delay times. During this period FarSpace changed its sound around pretty wildly while not being awesome. I’m going to encourage paying attention to reverbs […]

Dual Mono Verbs

Verbs are my first reverb attempts. These freebies are unusual in several ways: first, they’re a lot like a complicated multiple-echo system with very little allpassing. Second, since they’re dual mono they’ll widen ambience since hard panned stereo sends automatically get a hard-panned return. Third, they’re set up so that you pick a different one to […]
