delayk
delayk — Delays an input signal by some time interval.
Initialization
idel -- delay time (in seconds) for delayk. It is rounded to the nearest integer multiple of a k-cycle (i.e. 1/kr).
imode -- sum of 1 for skipping initialization (e.g. in tied notes) and 2 for holding the first input value during the initial delay, instead of outputting zero. This is mainly of use when delaying envelopes that do not start at zero.
imdel -- maximum delay time for vdel_k, in seconds.
Performance
kr -- the output signal. Note: neither of the opcodes interpolate the output.
ksig -- the input signal.
kdel -- delay time (in seconds) for vdel_k. It is rounded to the nearest integer multiple of a k-cycle (i.e. 1/kr).
Examples
Here is an example of the delayk opcode. It uses the file delayk.csd.
