class:: Decay
summary:: Exponential decay
related:: Classes/Decay2
categories:: UGens>Filters>Linear, UGens>Envelopes
Description::
This is essentially the same as link::Classes/Integrator:: except that
instead of supplying the coefficient directly, it is calculated from a 60
dB decay time. This is the time required for the integrator to lose 99.9%
of its value or -60dB. This is useful for exponential decaying envelopes
triggered by impulses.
classmethods::
method::ar, kr
argument::in
The input signal.
argument::decayTime
60 dB decay time in seconds.
argument::mul
argument::add
Examples::
code::
plot({ Decay.ar(Impulse.ar(1), 0.01) });
// used as an envelope
play({ Decay.ar(Impulse.ar(XLine.kr(1,50,20), 0.25), 0.2, PinkNoise.ar, 0) });
