## 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.

$\displaystyle QUANTIZE(x;\mbox{pre},\mbox{levels},\mbox{post}) = \frac{\mbox{FLOOR}(\mbox{levels} * \mbox{pre} * x) * \mbox{post}}{\mbox{levels}}$

## 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).

### 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.
