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
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.
