class:: DelayC
summary:: Simple delay line with cubic interpolation.
related:: Classes/DelayL, Classes/DelayN, Classes/BufDelayC
categories:: UGens>Delays
Description::
Simple delay line with cubic interpolation. See also
link::Classes/DelayN:: which uses no interpolation, and
link::Classes/DelayL:: which uses linear interpolation. Cubic
interpolation is more computationally expensive than linear,
but more accurate.
The term "delay" is often used in electronic music to refer to a delay line with feedback. If you are looking for that, try CombC.
classmethods::
method::ar, kr
argument::in
The input signal.
argument::maxdelaytime
The maximum delay time in seconds. used to initialize the delay buffer size.
argument::delaytime
Delay time in seconds.
discussion::
note::
DelayC needs at least 4 samples buffer. Therefore the minimum code::maxdelaytime:: and code::delaytime:: must be code::SampleDur.ir * 4::.
::
Examples::
code::
(
// Dust randomly triggers Decay to create an exponential
// decay envelope for the WhiteNoise input source
{
z = Decay.ar(Dust.ar(1,0.5), 0.3, WhiteNoise.ar);
DelayC.ar(z, 0.2, 0.2, 1, z); // input is mixed with delay via the add input
}.play
)
(
// recursive application of delay.
{
z = Decay2.ar(Dust.ar(1, 0.5), 0.01, 0.1, Saw.ar(100 + [0, 1]));
5.do { |i| z = DelayC.ar(RLPF.ar(z, Rand(100, 3000), 0.03), 1, 1 / (2**i), 1, z * 0.5) };
z
}.play
)
