Notes on how our plugins are built. What is inside the reverb engine, the decisions behind it, and what shipping a first release actually involves.
A reverb has at least six parameters that genuinely change the sound. We put five of them behind a single control, and then spent a release working out how to give them back without breaking anything.
The core of EvoraVerb is a feedback delay network. Eight delay lines, each feeding all the others through a matrix. Here is what is actually inside it and why each choice is there.
Long tails are where artificial reverbs give themselves away, and the culprit is almost always the modulation. Not its presence, its regularity.
Most of the work in a long reverb is not in making it sound good. It is in stopping a feedback loop that runs for twelve seconds from quietly destroying itself.
