@section{description}
Simple delay line with linear interpolation. See also
link::Classes/DelayN:: which uses no interpolation, and
link::Classes/DelayC:: which uses cubic 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 CombL.
