What this does

Praat script.

Process Description: The Temporal Erosion Effect creates a massive, sustained, and non-recurrent wash of reverb with a characteristic logarithmic decay. The term "Erosion" refers to the way the sound slowly dissolves into a diffused, highly randomized texture, primarily achieved through advanced Convolution Reverb techniques.
