Hierarchy

Constructor

new OmniOscillator (
frequency?:Frequency ,

The initial frequency of the oscillator.

type?:OmniOscillatorType

The type of the oscillator.

) => OmniOscillator
new OmniOscillator (
options?:Partial<OmniOscillatorOptions >
) => OmniOscillator

Properties

baseType #

OscillatorType | "pwm" | "pulse"

The base type of the oscillator. See Oscillator.baseType


const omniOsc = new Tone.OmniOscillator(440, "fmsquare4");
console.log(omniOsc.sourceType, omniOsc.baseType, omniOsc.partialCount);

blockTime #

readonly Seconds

The number of seconds of 1 processing block (128 samples)


console.log(Tone.Destination.blockTime);

channelCount #

number

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 #

ChannelCountMode

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.

  • "max" - computedNumberOfChannels is the maximum of the number of channels of all connections to an input. In this mode channelCount is ignored.
  • "clamped-max" - computedNumberOfChannels is determined as for "max" and then clamped to a maximum value of the given channelCount.
  • "explicit" - computedNumberOfChannels is the exact value as specified by the channelCount.

channelInterpretation #

ChannelInterpretation

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".

context #

BaseContext

The context belonging to the node.

count #

IsFatOscillator<OscType , number >

The number of detuned oscillators when sourceType === "fat". See FatOscillator.count

debug #

boolean

disposed #

readonly boolean

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.

harmonicity #

readonly IsAmOrFmOscillator<OscType , Signal<"positive" > >

Harmonicity is the frequency ratio between the carrier and the modulator oscillators. See AMOscillator or FMOscillator

input #

undefined

Sources have no inputs

modulationFrequency #

readonly IsPWMOscillator<OscType , Signal<"frequency" > >

The modulationFrequency Signal of the oscillator when sourceType === "pwm" see PWMOscillator

Range: 0.1 to 5

modulationIndex #

readonly IsFMOscillator<OscType , Signal<"positive" > >

The modulation index when the sourceType === "fm" See FMOscillator.

modulationType #

IsAmOrFmOscillator<OscType , ToneOscillatorType >

The type of the modulator oscillator. Only if the oscillator is set to "am" or "fm" types. See AMOscillator or FMOscillator

mute #

boolean

Mute the output.


const osc = new Tone.Oscillator().toDestination().start();
// mute the output
osc.mute = true;

numberOfInputs #

const node = new Tone.Gain();
console.log(node.numberOfInputs);

numberOfOutputs #

readonly number

The number of outputs of the AudioNode.


const node = new Tone.Gain();
console.log(node.numberOfOutputs);

onstop #

onStopCallback

The callback to invoke when the source is stopped.

output #

OutputNode

The output note

partials #

number []

The value is an empty array when the type is not "custom". This is not available on "pwm" and "pulse" oscillator types. See Oscillator.partials

sampleTime #

console.log(Tone.Transport.sampleTime);

sourceType #

OmniOscSourceType

The source type of the oscillator.


const omniOsc = new Tone.OmniOscillator(440, "fmsquare");
console.log(omniOsc.sourceType); // 'fm'

spread #

IsFatOscillator<OscType , Cents >

The detune spread between the oscillators when sourceType === "fat". See FatOscillator.count

state #

readonly BasicPlaybackState

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();

type #

OmniOscillatorType

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;

static version #

string

The version number semver

volume #

Param<"decibels" >

The volume of the output in decibels.


const source = new Tone.PWMOscillator().toDestination();
source.volume.value = -6;

width #

readonly IsPulseOscillator<OscType , Signal<"audioRange" > >

The width of the oscillator when sourceType === "pulse". See PWMOscillator.width
