summary:: When input falls below a threshhold, evaluate doneAction.
categories:: UGens>Synth control, UGens>Analysis>Amplitude
Description::
When input falls below a threshhold, evaluate doneAction. If the input
signal starts with silence at the beginning of the synth's duration, then
DetectSilence will wait indefinitely until the first sound before
starting to monitor for silence.
classmethods::
method::ar, kr
argument::in
The input signal.
argument::amp
When input falls below this, evaluate
code::doneAction:: .
argument::time
The minimum duration for which input must fall below
code::amp:: before this triggers.
argument::doneAction
An integer representing the doneAction. See
link::Reference/UGen-doneActions:: for more detail.
returns::
This UGen outputs 1 if silence is detected, otherwise 0.
Examples::
code::
(
SynthDef("detectSilence-help", { arg out;
var z;
z = SinOsc.ar(Rand(400, 700), 0, LFNoise2.kr(8, 0.2).max(0));
DetectSilence.ar(z, doneAction:2);
Out.ar(out, z);
}).send(s);
)
s.sendMsg("/s_new", "detectSilence-help", -1);
s.sendMsg("/s_new", "detectSilence-help", -1);
s.sendMsg("/s_new", "detectSilence-help", -1);
(
Task({
loop({
s.sendMsg("/s_new", "detectSilence-help", -1);
[0.5, 1].choose.wait;
})
}).play;
