Also called “feedback,” among other things, regeneration is signal fed back through an effects processor to intensify, or extend an effect. For example, in a delay effect, signal passes through the processor, is delayed and sent out as an echo of the original sound. If some of the delayed signal is tapped off and sent through the delay circuit again, a second repeat will result. By increasing the amount of signal sent back through (or fed back, or regenerated) the number of repeats is increased. Another example: On a flanger, when signal is regenerated through the flanging circuit, the effect becomes more deep, or intense.
