Buffer based simple delay line with cubic interpolation.
|
|
|
|
Simple delay line with cubic interpolation which uses a buffer for
|
|
its internal memory. See also buf-delay-n which uses no
|
|
interpolation, and buf-delay-l which uses linear interpolation. Cubic
|
|
interpolation is more computationally expensive than linear, but
|
|
more accurate.
|
|
|
|
See also delay-c.
|
|
|
|
buf - buffer number.
|
|
in - the input signal.
|
|
delaytime - delay time in seconds.
