Simple delay line with cubic interpolation which uses a buffer for its internal memory. See also BufDelayN which uses no interpolation, and BufDelayL which uses linear interpolation. Cubic interpolation is more computationally expensive than linear, but more accurate.
NOTE: The buffers provided to any of the BufDelay units must be one channel. If you want to delay a multichannel signal, you must provide as many separate (one-channel) buffers as there are input channels.
