9 Simple delay line with no interpolation which uses a buffer for its
10 internal memory. See also link::Classes/BufDelayL:: which uses linear
11 interpolation, and link::Classes/BufDelayC:: which uses cubic
12 interpolation. Cubic interpolation is more computationally expensive
13 than linear, but more accurate.
23 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.::
29 Delay time in seconds.
36 Warning:: For reasons of efficiency, the effective buffer size is limited to the previous power of two. So, if 44100 samples are allocated, the maximum delay would be 32768 samples.
