Moorer Reverb

What it is

A reverb built on James A. Moorer's design: a tapped FIR reproduces the early reflections, feeding a bank of parallel comb filters and an allpass diffuser that build the dense late tail. Reverb time sets how long the tail decays, Mix blends dry and wet, Output trims the wet level, and Early/Late balances the early-reflection FIR against the late reverberation. An Early reflections selector chooses between a 7-tap FIR and a denser 19-tap FIR early-reflection pattern.

How it works

Reverb time sets the comb feedback (via Moorer's approximation); the six combs run in parallel and are averaged, then passed through an allpass stage and a final delay, while the early-reflection taps and comb delays scale with the sample rate. Everything advances one sample-frame per tick, as required by WaveWarp's sample-per-sample engine.
