What this does

Praat script.

Process Description: This script is an incredibly powerful and flexible Generative Sound Design System. It uses a layered approach to create evolving ambient textures (soundscapes or drones), where multiple synthetic voices interact and shift over time. The core strength of this system is that it decouples the Synthesis Mode (the sound source) from the Spatial Mode (the sound environment), allowing for a huge range of final results.
