The Delay is most commonly used to create echo effects on your audio signals. It is called a delay because it delays the incoming signal in time and repeats this process. A delay is great to achieve a sense of space or distance in your mix.
Set the time between each echo repeat.
Set how much of the delayed signal will be fed back into the delay. Increase or decrease the delay taps.
Use mix to control the balance between the original sound and the signal of the delay.
Use this to apply high cut filtering to the delay taps.
Set the stereo bounce of the delay taps. Use this to shift each delay tap between left and right speakers to create ping pong delays.
The offset knob applies a small time difference or a shift between the delay times of the left and right audio signal.
