Field Detail

frequency

public SynthInput frequency

Frequency of filter cutoff in Hertz. SIGNAL_TYPE_FULL_RANGE

Q

public SynthInput Q

Q controls resonance of filter. A value greater than 1.0 will cause the filter to resonate, or "self-oscillate", with a peak at the specified frequency. A value from 1.0 to 50.0 is typical with higher values being more resonant.

amplitude

public SynthInput amplitude

Amplitude of Output
