About

Knorr

Enhance monophonic low-frequency audio with unique overtones. This plugin uses advanced modulation to add intensity and edge to bass sounds, going beyond standard distortion or filtering. It's designed for AUv3 compatible hosts like GarageBand.

Highlights
  • Adds overtones to low-frequency audio
  • Uses filtering, amplitude, and frequency modulation
  • XY Pad for bandwidth and energy control
  • Adjustable Range and Level controls
  • Bite setting for modulation intensity
  • Frequency Response graph

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. Although Knorr is developed with bass sounds in mind, it can be used on any monophonic sound source as long as there is audio content available in the low mids (and below). **User interface** XY Pad - Controls the bandwidth and amount of energy sent to the algorithm. Click and drag to move the marker. Range (X-axis) - Sets a low pass filter frequency of the signal to be sent to the algorithm. Spans from 100 Hz to 1 kHz. Level (Y-axis) - Sets the level of the low passed audio content. Bite (SOFT, MEDIUM, HARD) - Alters the amount of intensity of the modulations. Output - Sets the output level. Bypass - Turns the effect on or off. Frequency Response graph - Shows the frequency response of the internal modulation signal. Note that Knorr is a AUv3 only and and needs to be launched via a AUv3 compatible host like GarageBand, Cubasis, Auria or similar. It will not work as a stand alone application.
