A chorus generator uses several delays that vary independently from 15 to 35 milliseconds. When the various delayed signals are mixed, the variations in pitch add spaciousness and the illusion of multiple voices. While distortion is often perceived negatively, useful and effective distortion types exist. Distortion from guitar effects processors, for example, can be great fun when used carefully. This describes a type of audio mixer combining two audio signals that outputs only their sum and difference, but not the frequencies found in the original signals.
Vocal processing is one popular use for ring modulation.
Ring modulators are interesting noisemakers and tricky to use. This makes it ideal for processing political speeches, among other uses. Inc. All rights reserved.
