Class Oscillator.FrequencyModulatedOscillator

java.lang.Object

org.openimaj.audio.generation.Oscillator.FrequencyModulatedOscillator

All Implemented Interfaces:

Oscillator

Enclosing interface:

Oscillator

public static class Oscillator.FrequencyModulatedOscillator
extends Object
implements Oscillator

Frequency modulation of wave types. We use a carrier wave that generates a tone at the required frequency and modulate with the wave that is the modulation wave by altering the time (phase) offset of the carrier using the modulation wave.
