Description::
|
|
|
|
Simple delay line with linear interpolation. See also
|
|
link::Classes/DelayN:: which uses no interpolation, and
|
|
link::Classes/DelayC:: which uses cubic 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 CombL.

|
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.
|
|
|
|
argument::mul
|
|
Output will be multiplied by this value.
|
|
|
|
argument::add
|
|
This value will be added to the output.
|

|
|
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);
|
|
DelayL.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 = DelayL.ar(RLPF.ar(z, Rand(100, 3000), 0.03), 1, 1 / (2**i), 1, z * 0.5) };
