GreaterThanZero

GreaterThanZero outputs 1 when the input is strictly greater than zero


return Tone.Offline(() => {
	const gt0 = new Tone.GreaterThanZero().toDestination();
	const sig = new Tone.Signal(0.5).connect(gt0);
	sig.setValueAtTime(-1, 0.05);
}, 0.1, 1);

Constructor

new GreaterThanZero (
options?:Partial<GreaterThanZeroOptions >
) => GreaterThanZero

Properties

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.

debug #

boolean

Set this debug flag to log all events that happen in this class.

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.

numberOfInputs #

readonly number

The number of inputs feeding into the AudioNode. For source nodes, this will be 0.


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);

sampleTime #

readonly Seconds

The duration in seconds of one sample.


console.log(Tone.Transport.sampleTime);

static version #

string

The version number semver

Methods

player.chain(filter, distortion, Tone.Destination);
chain (
...nodes:InputNode []
) => this

connect #

connect the output of a ToneAudioNode to an AudioParam, AudioNode, or ToneAudioNode

connect (
destination:InputNode ,
outputNum= 0:number ,
inputNum= 0:number
) => this

disconnect #

disconnect the output

disconnect (
destination?:InputNode ,
outputNum= 0:number ,
inputNum= 0:number
) => this

dispose #

Dispose and disconnect

dispose ( ) => this

fan #

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);
fan (
...nodes:InputNode []
) => this

get #

Get the object's attributes.


const osc = new Tone.Oscillator();
console.log(osc.get());

static getDefaults #

Returns all of the default options belonging to the class.

getDefaults ( ) => ToneWithContextOptions

immediate #

Return the current time of the Context clock without any lookAhead.


setInterval(() => {
	console.log(Tone.immediate());
}, 100);
immediate ( ) => Seconds

now #

Return the current time of the Context clock plus the lookAhead.


setInterval(() => {
	console.log(Tone.now());
}, 100);
now ( ) => Seconds

set #

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);

const gain = new Tone.Gain();
console.log(gain.toFrequency("4n"));
toFrequency (
freq:Frequency
) => Hertz

toMaster # DEPRECATED

Connect the output to the context's destination node. See toDestination

toMaster ( ) => this

toSeconds #
