A non-band-limited pulse oscillator UGen. Outputs a high value of one and a low value of zero.
===Examples===
// modulating frequency
play { LFPulse.ar(XLine.kr(1, 200, 10), 0, 0.2) * 0.1 }
// modulating amplitude
play { LFPulse.kr(XLine.kr(1, 200, 10), 0, 0.2) * SinOsc.ar(440) * 0.1 }
// used as both oscillator and LFO
play { LFPulse.ar(LFPulse.kr(3, 0, 0.3).mulAdd(200, 200), 0, 0.2) * 0.1 }

oscillator frequency in Hertz
- iphase
initial phase offset in cycles (
0..1
). If you think of a buffer of one cycle of the waveform, this is the starting offset into this buffer. Hence, aniphase
of0.25
means that you will hear the first impulse after0.75
periods! If you prefer to specify the perceived delay instead, you could use aniphase
of-0.25 + 1
which is more intuitive. Note that the phase is not automatically wrapped into the range of0..1
, so putting aniphase
of-0.25
currently results in a strange initial signal which only stabilizes to the correct behaviour after one period! ''(init-time only)''- width
pulse width duty cycle from zero to one. If you want to specify the width rather in seconds, you can use the formula
width = freq * dur
, e.g. for a single sample impulse usewidth = freq * SampleDur.ir
.
