What this does

Praat script.

Process Description: This script describes an advanced, layered sound generator focused on creating complex, non-repeating ambient soundscapes, or drones. It uses several sophisticated synthesis techniques, but its most unique feature is the Layered Markov $\mathbfTexture}$ engine. The system works by generating up to eight independent audio streams (layers) using the chosen synthesis mode and combining them before applying spatial effects.

Quick start
