FMSynth is composed of two Tone.Synths where one Tone.Synth modulates the frequency of a second Tone.Synth. A lot of spectral content can be explored using the modulationIndex parameter. Read more about frequency modulation synthesis on Sound On Sound: Part 1, Part 2.
const fmSynth = new Tone.FMSynth().toDestination();
fmSynth.triggerAttackRelease("C5", "4n");
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.
The detune in cents
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 carrier's envelope
The frequency control
Harmonicity is the ratio between the two voices. A harmonicity of 1 is no change. Harmonicity = 2 means a change of an octave.
const amSynth = new Tone.AMSynth().toDestination();
// pitch the modulator an octave below oscillator
amSynth.harmonicity.value = 0.5;
amSynth.triggerAttackRelease("C5", "4n");
The instrument only has an output
The modulator's oscillator which is applied to the amplitude of the oscillator
The modulator's envelope
The modulation index which essentially the depth or amount of the modulation. It is the ratio of the frequency of the modulating signal (mf) to the amplitude of the modulating signal (ma) -- as in ma/mf.
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);
Invoked when the release has finished and the output is silent.
The carrier's oscillator
The glide time between notes.
The duration in seconds of one sample.
console.log(Tone.Transport.sampleTime);
The version number semver
The volume of the output in decibels.
const amSynth = new Tone.AMSynth().toDestination();
amSynth.volume.value = -6;
amSynth.triggerAttackRelease("G#3", 0.2);
Connect the output of this node to the rest of the nodes in series.
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
player.chain(filter, distortion, Tone.Destination);
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.
Get the level of the output at the given time. Measures the envelope(s) value at the time.
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;
Set the note at the given time. If no time is given, the note will set immediately.
const synth = new Tone.Synth().toDestination();
synth.triggerAttack("C4");
// change to F#6 in one quarter note from now.
synth.setNote("F#6", "+4n");
Sync the instrument to the Transport. All subsequent calls of triggerAttack and triggerRelease will be scheduled along the transport.
const fmSynth = new Tone.FMSynth().toDestination();
fmSynth.volume.value = -6;
fmSynth.sync();
// schedule 3 notes when the transport first starts
fmSynth.triggerAttackRelease("C4", "8n", 0);
fmSynth.triggerAttackRelease("E4", "8n", "8n");
fmSynth.triggerAttackRelease("G4", "8n", "4n");
// start the transport to hear the notes
Tone.Transport.start();
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"));
Trigger the attack of the note optionally with a given velocity.
const synth = new Tone.Synth().toDestination();
// trigger the note a half second from now at half velocity
synth.triggerAttack("C4", "+0.5", 0.5);
Trigger the attack and then the release after the duration.
const synth = new Tone.Synth().toDestination();
// trigger "C4" for the duration of an 8th note
synth.triggerAttackRelease("C4", "8n");
How long the note should be held for beforetriggering the release. This value must be greater than 0.
Trigger the release portion of the envelope
const synth = new Tone.Synth().toDestination();
synth.triggerAttack("C4");
// trigger the release a second from now
synth.triggerRelease("+1");
Unsync the instrument from the Transport
