What this does

Praat script.

Process Description: This script applies a chaotic spectral gain effect by multiplying the magnitude of each frequency bin in a Spectrum object by a unique, randomized factor. This technique immediately alters the sound's timbre, introducing metallic, noise-like, or shimmering artifacts, particularly focused on frequencies below a user-defined cutoff.

Quick start

In Praat, select a Sound object.
Run script… → Subtle Random Texture.praat.
Set parameters and click OK.
