class:: Peak
summary:: Track peak signal amplitude.
related:: Classes/PeakFollower
categories:: UGens>Analysis>Amplitude
Description::
Outputs the peak amplitude of the signal received at the input. When
a trigger occurs at the code::reset:: input, the maximum
output value is reset to the current value.
Internally, the absolute value of the signal is used, to prevent
underreporting the peak value if there is a negative DC offset. To obtain
the minimum and maximum values of the signal as is, use the
link::Classes/RunningMin:: and link::Classes/RunningMax:: UGens.
classmethods::
method::ar, kr
argument::in
The input signal.
argument::trig
Trigger. Resets the output value to the current input value. A trigger happens when the signal changes from non-positive to positive.
Examples::
code::
(
{
SinOsc.ar(
Peak.ar(Dust.ar(20), Impulse.ar(0.4)) * 500 + 200,
0, 0.2
)
}.play;
)
// follow a sine lfo, reset rate controlled by mouse x
(
{
SinOsc.ar(
Peak.kr(SinOsc.kr(0.2), Impulse.kr(MouseX.kr(0.01, 2, 1))) * 500 + 200,
0, 0.2
)
}.play;
)
