This effect allows you to delay sound for some amount of time to obtain sound effects like simple echo.
When delay amount is about 100 ms or more, it gives effect of reflections of sound (like echo),
and when delay is some milliseconds, it gives effect of phase-shift (you can get pseudo-stereo effect – just delay sound in one channel by some milliseconds).
This modification of delay allows you to define and edit change of filter’s parameters with profiles.
Delay is widely used for processing recorded voice or to get pseudo stereo effects (for the rhythm-guitar for example).
This audio effect supports profiles for all its parameters: Delay time amount, Feedback, Original signal mix,
Filtered signal mix, Delayed signal panorama, Lowpass and Highpass cut-off frequencies of filters of delayed signal.
