Looking for treble?

Knorr is a plugin that adds intensity and edge to a monophonic low frequency audio source (like a bass). The algorithm adds overtones to an existing sound in a way that isn’t possible with ordinary distortion or filtering.

The Knorr Algorithm

The underlying algorithm uses a combination of filtering, amplitude- and frequency modulation to process incoming audio. Knorr is developed with bass sounds in mind, but can be used on any monophonic sound source as long as there is audio content available in the low mids (and below).
