Optional options: Partial<OmniOscillatorOptions>Readonly contextThe context belonging to the node.
Set this debug flag to log all events that happen in this class.
Readonly detuneReadonly frequencySources have no inputs
Readonly nameThe callback to invoke when the source is stopped.
The output node
The volume of the output in decibels.
const source = new Tone.PWMOscillator().toDestination();
source.volume.value = -6;
Static versionThe version number semver
The base type of the oscillator.
const omniOsc = new Tone.OmniOscillator(440, "fmsquare4");
console.log(omniOsc.sourceType, omniOsc.baseType, omniOsc.partialCount);
The number of seconds of 1 processing block (128 samples)
console.log(Tone.Destination.blockTime);
channelCount is the number of channels used when up-mixing and down-mixing connections to any inputs to the node. The default value is 2 except for specific nodes where its value is specially determined.
channelCountMode determines how channels will be counted when up-mixing and down-mixing connections to any inputs to the node. The default value is "max". This attribute has no effect for nodes with no inputs.
channelInterpretation determines how individual channels will be treated when up-mixing and down-mixing connections to any inputs to the node. The default value is "speakers".
Indicates if the instance was disposed. 'Disposing' an instance means that all of the Web Audio nodes that were created for the instance are disconnected and freed for garbage collection.
The modulationFrequency Signal of the oscillator when sourceType === "pwm" see PWMOscillator
0.1
5
The type of the modulator oscillator. Only if the oscillator is set to "am" or "fm" types.
Mute the output.
const osc = new Tone.Oscillator().toDestination().start();
// mute the output
osc.mute = true;
The number of inputs feeding into the AudioNode. For source nodes, this will be 0.
const node = new Tone.Gain();
console.log(node.numberOfInputs);
The number of outputs of the AudioNode.
const node = new Tone.Gain();
console.log(node.numberOfOutputs);
The value is an empty array when the type is not "custom". This is not available on "pwm" and "pulse" oscillator types.
The duration in seconds of one sample.
The source type of the oscillator.
const omniOsc = new Tone.OmniOscillator(440, "fmsquare");
console.log(omniOsc.sourceType); // 'fm'
Returns the playback state of the source, either "started" or "stopped".
const player = new Tone.Player("https://tonejs.github.io/audio/berklee/ahntone_c3.mp3", () => {
player.start();
console.log(player.state);
}).toDestination();
The type of the oscillator. Can be any of the basic types: sine, square, triangle, sawtooth. Or prefix the basic types with "fm", "am", or "fat" to use the FMOscillator, AMOscillator or FatOscillator types. The oscillator could also be set to "pwm" or "pulse". All of the parameters of the oscillator's class are accessible when the oscillator is set to that type, but throws an error when it's not.
const omniOsc = new Tone.OmniOscillator().toDestination().start();
omniOsc.type = "pwm";
// modulationFrequency is parameter which is available
// only when the type is "pwm".
omniOsc.modulationFrequency.value = 0.5;
Connect the output of this node to the rest of the nodes in series.
Rest ...nodes: InputNode[]const player = new Tone.Player("https://tonejs.github.io/audio/drum-samples/handdrum-loop.mp3");
player.autostart = true;
const filter = new Tone.AutoFilter(4).start();
const distortion = new Tone.Distortion(0.5);
// connect the player to the filter, distortion and then to the master output

Get the object's attributes.
const osc = new Tone.Oscillator();
console.log(osc.get());
Sync the source to the Transport so that all subsequent
calls to start and stop are synced to the TransportTime
instead of the AudioContext time.
const osc = new Tone.Oscillator().toDestination();
// sync the source so that it plays between 0 and 0.3 on the Transport's timeline
osc.sync().start(0).stop(0.3);
// start the transport.
Tone.Transport.start();
// set it to loop once a second
Tone.Transport.loop = true;
Tone.Transport.loopEnd = 1;
Convert the incoming time to seconds. This is calculated against the current TransportClass bpm
const gain = new Tone.Gain();
setInterval(() => console.log(gain.toSeconds("4n")), 100);
// ramp the tempo to 60 bpm over 30 seconds
Tone.getTransport().bpm.rampTo(60, 30);
Static get
OmniOscillator aggregates all of the oscillator types into one.
