Simple delay line with no interpolation which uses a buffer for its internal memory. See also BufDelayL which uses linear interpolation, and BufDelayC which uses cubic interpolation. Cubic interpolation is more computationally expensive than linear, but more accurate.
| buf |
Buffer number. 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. |
| in |
The input signal. |
| delaytime |
Delay time in seconds. |
| mul | |
| add |
