quantizers.lib

Quantizers library. Its official prefix is qu.

This library provides utilities for pitch and signal quantization in Faust. It includes functions for mapping continuous inputs to discrete musical scales.

The Quantizers library is organized into 1 section:

Functions Reference

(qu.)quantize

Configurable frequency quantization tool. Snaps input frequencies to exact scale notes. Works for positive audio frequencies.

Usage

_ : quantize(rf,nl) : _

Where:

  • rf : frequency of the root note of the scale
  • nl : list of frequency ratios for each note relative to root

Test

qu = library("quantizers.lib");
quantize_test = qu.quantize(440, qu.ionian, hslider("input", 450, 100, 1000, 1));

Example

process = quantize(440, (1, 1.125, 1.25, 1.333, 1.5));

(qu.)quantizeSmoothed

Configurable frequency quantization tool. Smoothly transitions between scale notes. Works for positive audio frequencies.

Usage

_ : quantizeSmoothed(rf,nl) : _

Where:

  • rf : frequency of the root note of the scale

Test

qu = library("quantizers.lib");
quantizeSmoothed_test = qu.quantizeSmoothed(440, qu.ionian, hslider("input", 450, 100, 1000, 1));
