i see that PD has cosine and sawtooth objects. is there a square wave object? or do you use tables to create them?
Some methods:
1: You can create a rectangular wave by subtracting two sawtooth waves that have different phases, vary the phase difference to change the proportion of high and low in the wave, at a particular phase you have a square wave.
2: You can [clip~] a cosine wave, various amounts of pre-clip amplification change the "hardness" of the square wave. The Zexy library also has [>~].
- You can use tables with [tabread~] or [tabread4~] (there is also a
table osc but I've forgotten its exact name).
Note:
phasor~ is not band-limited, which means aliasing distortion can be audible, if you're using it as an audio oscillators. I think there are band-limited oscillator LADSPA plugins if you use Linux.
