Purpose

Echo repeats the incoming signal after a set delay and feeds the output back on itself for trailing repeats. It covers everything from a single slapback to long, decaying echo tails.

TouchDesigner Use

Insert it inline on a source or an effect send. Wire audio into in and out onward. Set Delay for the repeat time, Feedback for how many repeats you hear, and Drywet to balance the echoes against the dry signal.

Inputs And Outputs

• Input 0: in accepts mono or stereo PCM. It is required.
• Output 0: out emits the same shape as the input.

Main Controls

• Delay: time between repeats in milliseconds.
• Feedback: how much of the output is fed back in. Higher values give more repeats and longer tails.
• Drywet: balance between the dry input and the delayed signal.

Notes

• Feedback stays below full, so repeats decay rather than build up indefinitely.
• Short delays with high feedback give a metallic, resonant character; long delays give distinct repeats.
