Enclosing interface:

EffectFactory

public static class EffectFactory.RingModDef
extends Object

This class contains definitions for constructing a Ring Modulator object

The ring modulator multiplies an input signal by a carrier signal in the time domain, resulting in tremolo or inharmonic effects.

Edit properties of a RingModDef object then use EffectFactory.createRingMod() or EffectFactory.updateRingMod(EffectFilter, RingModDef) )} to transfer properties from RingModDef to the effect object.

Field Details

RING_MODULATOR_FREQUENCY

public float RING_MODULATOR_FREQUENCY

Sets the frequency of the carrier signal. If the carrier signal is slowly varying (less than 20 Hz), the result is a tremolo (slow amplitude variation) effect. If the carrier signal is in the audio range, audible upper and lower sidebands begin to appear, causing an inharmonic effect. The carrier signal itself is not heard in the output.

• MAX: 8000.0f
• MIN: 0.0f

RING_MODULATOR_HIGHPASS_CUTOFF

public float RING_MODULATOR_HIGHPASS_CUTOFF

Sets the frequency of the carrier signal. If the carrier signal is slowly varying (less than 20 Hz), the result is a tremolo (slow amplitude variation) effect. If the carrier signal is in the audio range, audible upper and lower sidebands begin to appear, causing an inharmonic effect. The carrier signal itself is not heard in the output.

• MAX: 8000.0f
• MIN: 0.0f

RING_MODULATOR_WAVEFORM

public int RING_MODULATOR_WAVEFORM

Controls which waveform is used as the carrier signal. Traditional ring modulator and tremolo effects generally use a sinusoidal carrier. Sawtooth and square waveforms are may cause unpleasant aliasing.

• 0: Sin
• 1: Triangle
• 2: Square
