Ableton/Live/UG/29 Audio Effect Reference/32 Reverb/03 Diffusion Network
29.32.3 Diffusion Network

- The Diffusion Network makes the tail after the early reflections.
- High and low shelf filters make decay depend on frequency. The high shelf models absorption by air, walls, people and carpet; the low shelf thins the decay. Either can be turned off to save CPU.
- Diffusion and Scale set density and coarseness; in very small rooms they strongly color the sound.
