What this does

Praat script.

Process Description: This script utilizes a core concept from Chaos Theory—the Logistic Map—to generate highly complex and evolving audio frequencies. It's a method of algorithmic composition where the sound isn't based on human-defined musical scales, but on the non-linear dynamics of a simple mathematical equation.

Quick start

Run script… → Logistic Map Synthesis.praat.
Set parameters and click OK.
