The upper diagram is for impulse response parameters. Drag a circle to set a parameter: amplitude envelope, lowpass filter envelope, stereo width envelope, "density" envelope.

Lowpass filter envelope is very important for that classic realistic feeling (slowly closing filter).

Density changes the character of the reverb.

The sound is built from early_reflections and late_reflections. Two knobs ("early" and "late") balance these. "Size" is for early while "length" is for late.

Sidechained compressor/gate. It gets control signal (sidechain input) from audio input but controls only reverb level. When "ratio" knob is to left, it is a gate, when "ratio" is to right it is a compressor.

Paragraphic equalizer with 10 bands. It filters the whole, final, reverb sound. Dry signal passes through untouched.

Modulation. amplitude and frequency of pitch oscillation. Very useful to "move" the sound. The reverb isn't "chorused". It is only "pitch shifted" (like a full wet chorus).

Incredibly transparent results.

A mix. Several parts are layered one by one. Reverb comes in and out.

Three instances of Verbera (room with sidechain dynamics set to gate, hall, modulated large hall).
