A single master output which is connected to the AudioDestinationNode (aka your speakers). It provides useful conveniences such as the ability to set the volume and mute the entire application. It also gives you the ability to apply master effects to your application. The Destination (output) belonging to the global Tone.js Context. See Destination
const oscillator = new Tone.Oscillator().start();
// the audio will go from the oscillator to the speakers
oscillator.connect(Tone.getDestination());
// a convenience for connecting to the master output is also provided:
oscillator.toDestination();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".
The context belonging to the node.
Set this debug flag to log all events that happen in this class.
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 number of channels the system can output
console.log(Tone.Destination.maxChannelCount);
Mute the output.
const oscillator = new Tone.Oscillator().start().toDestination();
setTimeout(() => {
// mute the output
Tone.Destination.mute = true;
}, 1000);
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 duration in seconds of one sample.
console.log(Tone.Transport.sampleTime);
The version number semver
The volume of the master output in decibels. -Infinity is silent, and 0 is no change.
const osc = new Tone.Oscillator().toDestination();
osc.start();
// ramp the volume down to silent over 10 seconds
Tone.getDestination().volume.rampTo(-Infinity, 10);
Add a master effects chain. NOTE: this will disconnect any nodes which were previously chained in the master effects chain.
// route all audio through a filter and compressor
const lowpass = new Tone.Filter(800, "lowpass");
const compressor = new Tone.Compressor(-18);
Tone.Destination.chain(lowpass, compressor);
All arguments will be connected in a row and the Master will be routed through it.
connect the output of a ToneAudioNode to an AudioParam, AudioNode, or ToneAudioNode
The output to connect from
The input to connect to
disconnect the output
connect the output of this node to the rest of the nodes in parallel.
const player = new Tone.Player("https://tonejs.github.io/audio/drum-samples/conga-rhythm.mp3");
player.autostart = true;
const pitchShift = new Tone.PitchShift(4).toDestination();
const filter = new Tone.Filter("G5").toDestination();
// connect a node to the pitch shift and filter in parallel
player.fan(pitchShift, filter);
Get the object's attributes.
const osc = new Tone.Oscillator();
console.log(osc.get());
Returns all of the default options belonging to the class.
Return the current time of the Context clock without any lookAhead.
setInterval(() => {
console.log(Tone.immediate());
}, 100);
Return the current time of the Context clock plus the lookAhead.
setInterval(() => {
console.log(Tone.now());
}, 100);
Set multiple properties at once with an object.
const filter = new Tone.Filter().toDestination();
// set values using an object
filter.set({
frequency: "C6",
type: "highpass"
});
const player = new Tone.Player("https://tonejs.github.io/audio/berklee/Analogsynth_octaves_highmid.mp3").connect(filter);
player.autostart = true;
Connect the output to the context's destination node.
const osc = new Tone.Oscillator("C2").start();
osc.toDestination();
Convert the input to a frequency number
const gain = new Tone.Gain();
console.log(gain.toFrequency("4n"));
Connect the output to the context's destination node. See toDestination
Convert the incoming time to seconds. This is calculated against the current Tone.Transport 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);
Convert the class to a string
const osc = new Tone.Oscillator();
console.log(osc.toString());
Convert the input time into ticks
const gain = new Tone.Gain();
console.log(gain.toTicks("4n"));
