Simple delay line with cubic interpolation. See also DelayN which uses no interpolation, and DelayL which uses linear interpolation. Cubic interpolation is more computationally expensive than linear, but more accurate.
The term "delay" is often used in electronic music to refer to a delay line with feedback. If you are looking for that, try CombC.
