Examples

Short delay with feedback to blur the input sound, or longer delay for discrete echoes

Arguments

max-delay [float]

Optional
Unitsms

The maximum delay time. Defaults to 10 ms if not specified.

initial-delay [float]

Optional
Unitsms

Initial delay time

gain [float]

Optional

Gain coefficient
