PING-PONG FIELD — User Guide
Praat script.
What this does
Praat script.
Process Description: The Ping-Pong Field Stereo script creates a complex, dense echo effect that simulates sound bouncing chaotically in an open, wide space. It achieves this by applying a large number of delayed copies of the signal that gradually increase in delay time, combined with a hard-panning (ping-pong) effect and a custom high-frequency (HF) sparkle filter to brighten the echoes.
Quick start
- In Praat, select a Sound object.
