Protoverb is an experimental free reverb plugin based on the idea of a “room simulator”. Most algorithmic reverbs try to avoid resonances or model the reflections of sound from a rooms walls. Protoverb does the opposite. It builds up as many room resonances as possible, modeling the body of air in the room. It therefore does not need to modulate or colour the signal. The result is a very natural sounding reverbration with some interesting features: Long standing frequencies resonate louder, as if the air takes some time to get excited. Multiple instruments don’t mash into a diffuse mud, they stay distinct. If you play a short melody, the room seems to repeat a ghost echo of that melody. Those properties are indeed found in churches and large halls, but they’re rarely found in conventional algorithmic reverbs.

To achieve this kind of stuff, Protoverb works with loads and loads of parallel, serial and networked delays. By all means, there is no mathematical formula that makes such a structure sound “just right”. As with all delay based reverbs, it’s down to trial and error, and maybe a lot of luck with random values. Therefore we designed Protoverb to present you with delay lines of random lengths and a random assembly of networking and feedback strategies. Which, if you’re lucky and you come across a great setting, you can submit to our website, along with a few details
