Convolution Reverb node: controls, inputs and a free patch

Convolution Reverb

A reverb whose room you design: shape (room, hall, chamber, tunnel), size, material, distance, decay time and stereo spread. The node builds that room's impulse response in the background and shows it. Load file uses a recorded impulse response instead (up to 10 s). It adds no latency.

What it does

Convolution Reverb is an audio effect: it changes the sound that flows through it. It takes audio in and gives audio out.

Try it

Make a long tunnel with a hard material for a metallic, echoing space.

Controls

Every control with a range can be driven by a modulator, a note, an audio level or a sketch.

Control	Range or options	Default
mix	0 to 1	1
size	0 to 1	0.449999988
material	0 to 1	0.5
distance	0 to 1	0.5
decay	0.1 to 10	1.79999995
spread	0 to 1	1

Example patch

This patch wires Convolution Reverb to what it needs and shows the result. Download it, then use File, Open in Infinite, or read it here: it is plain text.
