Protoverb: prototype reverb
A natural sounding reverb based on the concept of a room simulator. Protoverb is an experimental researchware plug-in, developed to aid our research. Download and use it for free.
What is Protoverb?
Protoverb is an experimental room simulator reverb. Most algorithmic reverbs try to avoid resonances or model the reflections of sound from a room’s walls. Protoverb does the opposite. It builds up as many room resonances as possible, modelling the body of air in the room. No need to modulate or colour the signal. The result is a very natural sounding reverberation with interesting characteristics:
- Notes held for a longer time tend to build up resonance, as if the air takes a while to get excited
- Multiple instruments remain distinct, without disappearing in a wash
- When you play a short melody, the room seems to repeat a ghost echo of that melody
These properties are found in churches and large halls, but are rarely in conventional algorithmic reverbs.
To achieve this, Protoverb works with many parallel, serial and networked delays. With such a structure, no mathematical formula can make it sound right, it is down to trial and error (and luck) using random values. Protoverb generates random delay line lengths, networks and feedback strategies. If you are lucky you will find a great setting, which you can send to us.
The text box at the bottom of Protoverb’s interface contains a text string made up of two random parts. The first half dictates the network structure, strategies for spatial layout and distribution of delay taps, strategies for finding useful delay lengths and so on. The second half is a seed for a pseudo-random number generator—used to set various parameters such as the average delay length, which prime number to choose (if any) etcetera.
You can either edit the text, or randomise each part independently using the buttons below the text box.

The current version of Avid's toolkit for building AAX plug-ins is not compatible with the Apple SDK needed to build plug-ins for Apple's new ARM/M1 processors. We are therefore not able to provide updated AAX versions on macOS, neither for Intel CPUs, nor for Apple M1. If you're a Pro Tools user on macOS, please continue using the previous version of Protoverb for the time being. Once the AAX toolkit supports Apple's M1 processor architecture, we will provide new AAX versions for macOS, with support for Big Sur and both Intel and Apple M1 CPUs.
