# ER-301/Grid Quantizer

(diff) ← Older revision | Latest revision (diff) | Newer revision → (diff)

## 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)

{Pitfall|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.

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

## Parameters

### pre

This gain multiplies the signal before quantization.
