A non-band-limited pulse oscillator. Outputs a high value of one and a low value of zero.
| freq |
frequency in Hertz |
| iphase |
initial phase offset in cycles ( 0..1 ) |
| width |
pulse width duty cycle from zero to one. |
a plot:
{ LFPulse.ar(Line.kr(100, 800, 0.1)) }.plot(0.1);
50 Hz wave:
{ LFPulse.ar(50) * 0.1 }.play;
modulating frequency:
{ LFPulse.ar(XLine.kr(1, 200, 10), 0, 0.2, 0.1) }.play;
amplitude modulation:
{ LFPulse.kr(XLine.kr(1, 200, 10), 0, 0.2) * SinOsc.ar(440) * 0.1 }.play;
used as both Oscillator and LFO:
{ LFPulse.ar(LFPulse.kr(3, 0, 0.3, 200, 200), 0, 0.2, 0.1) }.play;
scope:
Server.internal.boot; { LFPulse.ar(500, 0, MouseX.kr, 0.5) }.scope;
compare with band limited Pulse UGen:
(
{
[
Pulse.ar(100, 0.3, 0.5),
LFPulse.ar(100, 0, 0.3, 0.5)
] * 0.2
