class:: LeastChange
summary:: Output least changed
related:: Classes/MostChange, Classes/LastValue
categories:: UGens>Maths
Description::
Output the input that changed least.
classmethods::
method::ar, kr
argument::a
Input signal A.
argument::b
Input signal B.
examples::
code::
(
d = { arg amp=1.0;
var in1, in2;
in1 = LFNoise0.ar(800, amp);
in2 = SinOsc.ar(800);
LeastChange.ar(in1, in2) * 0.1;
}.play;
)
d.set(\amp, 0.1);
d.set(\amp, 0);
d.set(\amp, 3);
d.free;
::
the control that changed least is used as output:
code::
(
d = { arg freq=440;
var internalFreq;
internalFreq = LFNoise0.ar(0.3, 300, 800);
SinOsc.ar(
LeastChange.kr(freq, internalFreq) // two sources of change: one external, one internal
) * 0.1
}.play
);
d.set(\freq, 800);
d.set(\freq, 900);
d.free;
