public final class OscillatorNode
extends AudioScheduledSourceNode

A band-limited periodic waveform, the Web Audio OscillatorNode. Mono.

OfflineAudioContext audio = new OfflineAudioContext(2, 44100, 44100);
OscillatorNode osc = audio.createOscillator();
osc.setType(OscillatorType.SAWTOOTH);
osc.getFrequency().setValue(220);
osc.connect(audio.getDestination());
osc.start();
osc.stop(audio.getCurrentTime() + 1);

Method Summary

Modifier and Type	Method	Description
AudioParam	getDetune()	A detune in cents applied on top of the frequency, 0 by default; an audio rate parameter.
AudioParam	getFrequency()	The frequency in Hz, 440 by default; an audio rate parameter.
OscillatorType	getType()	The waveform.
void	setPeriodicWave(PeriodicWave wave)	Plays a custom waveform; the type becomes CUSTOM.
void	setType(OscillatorType type)	Selects a standard waveform.

Method Details

getFrequency

public AudioParam getFrequency()

The frequency in Hz, 440 by default; an audio rate parameter.

Returns

the parameter

getDetune

public AudioParam getDetune()

A detune in cents applied on top of the frequency, 0 by default; an audio rate parameter.

Returns

the parameter

getType

public OscillatorType getType()

The waveform.

Returns

the type, CUSTOM after setPeriodicWave(PeriodicWave)

setType

public void setType(OscillatorType type)

Selects a standard waveform.

Parameters

• type: any type but CUSTOM

Throws

• IllegalArgumentException: for CUSTOM; use setPeriodicWave(PeriodicWave)

setPeriodicWave

public void setPeriodicWave(PeriodicWave wave)

Plays a custom waveform; the type becomes CUSTOM.

Parameters

• wave: the waveform
