What this does

Praat script.

Process Description: The Bursts and Sparse Taps Convolution script creates a dual-texture echo effect: it combines a few sparse, distinct echoes with several instances of dense, chaotic clusters. This is achieved by building the convolution kernel from two distinct components—manually placed taps and randomly placed Gaussian bursts.

Quick start

In Praat, select a Sound object.
Run script… → convolve_PING-PONG.praat.
Set parameters and click OK.
