Optional options: Partial<LFOOptions>Readonly amplitudeThe amplitude of the LFO, which controls the output range between the min and max output. For example if the min is -10 and the max is 10, setting the amplitude to 0.5 would make the LFO modulate between -5 and 5.
Readonly contextThe context belonging to the node.
If the input value is converted using the units
Set this debug flag to log all events that happen in this class.
Readonly frequencyThe frequency value of the LFO
Readonly inputThere is no input node
Readonly nameThe name of the class
Readonly outputThe output of the LFO
Static versionThe version number semver
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 maximum output of the LFO.
The minimum output of the LFO.
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 oscillator's partials array.
The phase of the LFO.
The duration in seconds of one sample.
Returns the playback state of the source, either "started" or "stopped".
The type of the oscillator.
Connect the output of this node to the rest of the nodes in series.

Get the object's attributes.

Set multiple properties at once with an object.

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
LFO stands for low frequency oscillator. LFO produces an output signal which can be attached to an AudioParam or Tone.Signal in order to modulate that parameter with an oscillator. The LFO can also be synced to the transport to start/stop and change when the tempo changes.
