public class PulseOscillatorBL
extends SynthOscillator

PulseOscillatorBL unit that is bandlimited to prevent aliasing artifacts. This will sound better then PulseOscillator, particularly at higher frequencies. It will also take more CPU power to calculate

Field Detail

width

public SynthInput width

Level for comparator used to generate pulse wave. 0 gives a 50% duty cycle pulse wave. Positive values cause the positive portion of the pulse to be wider than the negative. Negative values cause the negative portion of the pulse to be wider than the positive. The range is -1.0 to +1.0, defaults to 0.0.
