class::LFPulse
summary::pulse oscillator
categories::UGens>Generators>Deterministic
related::Classes/LFSaw
description::
A non-band-limited pulse oscillator. Outputs a high value of one and a low value of zero.
classmethods::
method::ar, kr
argument::freq
frequency in Hertz
argument::iphase
initial phase offset in cycles ( 0..1 )
argument::width
pulse width duty cycle from zero to one.
argument::mul
argument::add
instancemethods::
private::signalRange
examples::
a plot:
code::
{ LFPulse.ar(Line.kr(100, 800, 0.1)) }.plot(0.1);
::
50 Hz wave:
code::
{ LFPulse.ar(50) * 0.1 }.play;
::
modulating frequency:
code::
{ LFPulse.ar(XLine.kr(1, 200, 10), 0, 0.2, 0.1) }.play;
::
amplitude modulation:
code::
{ LFPulse.kr(XLine.kr(1, 200, 10), 0, 0.2) * SinOsc.ar(440) * 0.1 }.play;
::
used as both Oscillator and LFO:
code::
{ LFPulse.ar(LFPulse.kr(3, 0, 0.3, 200, 200), 0, 0.2, 0.1) }.play;
::
scope:
code::
{ LFPulse.ar(500, 0, MouseX.kr, 0.5) }.scope;
::
compare with band limited Pulse UGen:
code::
(
{
[
Pulse.ar(100, 0.3, 0.5),
LFPulse.ar(100, 0, 0.3, 0.5)
] * 0.2
}.scope(bufsize: 44100, zoom: 5)
)
