LFPulse

oscillator frequency in Hertz

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, an iphase of 0.25 means that you will hear the first impulse after 0.75 periods! If you prefer to specify the perceived delay instead, you could use an iphase of -0.25 + 1 which is more intuitive. Note that the phase is not automatically wrapped into the range of 0..1 , so putting an iphase of -0.25 currently results in a strange initial signal which only stabilizes to the correct behaviour after one period!

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 use width = freq * SampleDur.ir .
