class:: Impulse
summary:: Impulse oscillator.
related:: Classes/Blip
categories:: UGens>Generators>Deterministic
Description::
Outputs non-bandlimited single sample impulses.
classmethods::
method::ar, kr
argument::freq
Frequency in Hertz.
argument::phase
Phase offset in cycles (0..1).
argument::mul
Output will be multiplied by this value.
argument::add
This value will be added to the output.
discussion::
An Impulse with frequency 0 returns a single impulse.
Examples::
code::
{ Impulse.ar(800, 0.0, 0.5, 0) }.play
{ Impulse.ar(XLine.kr(800,100,5), 0.0, 0.5, 0) }.play
::
modulate phase:
code::
{ Impulse.ar(4, [0, MouseX.kr(0, 1)], 0.2) }.play;
::
an Impulse with frequency 0 returns a single impulse:
code::
SynthDef(\imp, { OffsetOut.ar(0, Impulse.ar(0)); FreeSelf.kr(Impulse.kr(0)); }).add;
fork { (1 / (1..60).scramble).do { |dt| Synth.grain(\imp); dt.wait } };
