FarSpace3 is the latest Airwindows algorithmic reverb, drawing on what was learned from AllSpace, and taking it in some new directions. FarSpace3 is $49.99 and includes AllSpace, which is a more CPU-hungry, flexible, dual-mono reverb.
FarSpace3 works like this:
Room Size is not RT60. It's hooked to the actual internal delay buffers, and set up so that it can be adjusted 'live'... even though doing that smashes the buffers. It's designed to do this as gently as possible, like AllSpace was.
Liveness is RT60, with a full range of reverb dwell times available.
Brightness helps control treble in the reverb sound.
Predelay is what you'd expect- pre-delay for the reverb. It is wired to the Room Size control, so that it retains the same relation to the 'room size' at all times, as that is changed. Predelay operates using buffers, so altering it on the fly can cause noises, like with AllSpace.
Lastly, the Dry/Wet control is there and defaults to 100% wet for use on reverb auxes. FarSpace3 is the 'normal' reverb- it's exceptional in terms of sound, but behaves normally, returning stereo sounds from any inputs (it does take stereo input, if you have one for it).
AllSpace is the more unusual reverb of the two, in several ways. Each part of AllSpace has its own special qualities. From the top of the plugin:
Room Size is not RT60. It's hooked to the actual internal delay buffers, and set up so that it can be adjusted 'live'... even though doing that smashes the buffers. It's designed to do this as gently as possible, though a sound will probably be created regardless- that may or may not be annoying in the context of the mix, but it gives the possibility of changing every conceivable aspect of the reverb in 'scenes' through automation. Extreme, extreme settings are possible with this.
Liveness is RT60, but with a twist- it's set up to self-limit and also to replace existing content with new sound coming in, which means that you can adjust it from very short to infinite. Be careful with it because it's set up to give infinite or near-infinite reverb at any tone setting, and is capable of regenerating too much and distorting the output- but the sweet spot for working with very long sustains is huge thanks to the self-limiting.
Smoke is an Airwindows exclusive- it's a technique from the old 'Chrome Oxide' plugin applied to the internal buffers of an algorithmic reverb. You morph from more of the traditional, crystalline algorithmic reverb sound, to a more naturalized texture at high Smoke levels. It's a subtle difference, but it's different from simple EQ as it's breaking up the reverb tails rather than just filtering them. FarSpace uses this technology, too.
Treble is what you'd think, except that it is not a shelf, or tone control on the reverb output- it's an averaging process built into the reverb buffers themselves, so it's more like 'room materials and furnishings'. All these settings default to 0.5, which is a neutral, workable starting point.
Bass is also built into the reverb buffers- it's very useful for giving you a less 'concrete digital room' sound, and at extreme low settings can go to a classic bright ambience. Like Treble and Smoke, automating this doesn't cause any artifacts- and because it is not an output tone control, it can be used within a mix to suppress the fullness of the reverb sound on the fly (duck it briefly to mute the verb and then put it back to what it was)
Predelay is what you'd expect- pre-delay for the reverb. It is wired to the Room Size control, so that it retains the same relation to the 'room size' at all times, as that is changed. Predelay operates using buffers, so altering it on the fly can cause noises, though it's set up to blank areas of buffer that it's reclaiming (to avoid even worse noises).
Lastly, the Dry/Wet control is there and defaults to 100% wet for use on reverb auxes, but will also let you place the plugin on individual tracks. That's unusually relevant, because AllSpace has a unusual trait for a reverb- it is an N to N reverb. That's multiple-mono, an old studio trick that will make your mix space crazy wide. It also allows for another classic trick- take a spare aux, put Gain on it set to flip channels, and direct that to your AllSpace aux, and you have a L/R swap reverb send- used for balancing single hard-panned rhythm guitars. And, if you have a sound swooping across the stereo field, with an AllSpace send it will leave a 'trail of fire' as it goes... and if you have an instance on a mono channel, that's half the CPU of a stereo instance, automatically.
Yes, it automatically works in surround, too- that's natural to an N to N configured plugin.
Try the demo of this to see if it'll work for you! You're not allowed to use the demo for actual work. It politely mutes itself briefly every couple minutes, and that's the only thing it does to spite you. It won't expire or do anything to you, and when you get the actual plugin, throw away the demo and put the real version in its place and most software should replace saved instances of the demo with the real thing seamlessly, retaining any settings. Please support my cooperative, unhostile demos with sales of the real software.
