Inherits: AudioEffect < Resource < Reference < Object

Adds a delay audio effect to an audio bus. Plays input signal back after a period of time.

Two tap delay and feedback options.


Plays input signal back after a period of time. The delayed signal may be played back multiple times to create the sound of a repeating, decaying echo. Delay effects range from a subtle echo effect to a pronounced blending of previous sounds with new sounds.
