Applications

  • adding grit to sounds (i.e. similar to bit crushing)
  • restricting modulation signals to a finite set of levels (i.e. stair-case function)

This is not a pitch quantizer because this unit has no knowledge of 1V/oct or scales. A separate (and much more complicated) upcoming unit will take care of these tasks.


Description

This simple unit quantizes the incoming signal to a given number of levels with separate controls for pre-gain and post-gain.

Parameters

pre

Control Type Has Sub-chain? Fader Range Fader Scale
Simple Fader no -10 to 10 linear gain


This gain multiplies the signal before quantization.

levels

Control Type Has Sub-chain? Fader Range Fader Scale
Simple Fader no 0 to 36 linear


This parameter sets the total number of output levels that exist between -0.5 and 0.5 (or equivalently, between 0 and 1). In other words, assuming the pre- and post-gains are 1, the distance between one output step and the next output step is: Failed to parse (MathML with SVG or PNG fallback (recommended for modern browsers and accessibility tools): Invalid response ("Math extension cannot connect to Restbase.") from server "https://en.wikipedia.org/api/rest_v1/":): {\displaystyle \frac{1}{\mbox{levels}}} .

post

Control Type Has Sub-chain? Fader Range Fader Scale
Simple Fader no -10 to 10 linear gain


This gain multiplies the signal after quantization.
