Wraps the native Web Audio API WaveShaperNode.
import { Oscillator, Signal, WaveShaper } from "tone";
const osc = new Oscillator().toDestination().start();
// multiply the output of the signal by 2 using the waveshaper's function
const timesTwo = new WaveShaper((val) => val * 2, 2048).connect(osc.frequency);
const signal = new Signal(440).connect(timesTwo);The function used to define the values.The mapping function should take two arguments:the first is the value at the current positionand the second is the array position.If the argument is an array, that array will beset as the wave shaping function. The inputsignal is an AudioRange [-1, 1] value and the outputsignal can take on any numerical values.
The number of seconds of 1 processing block (128 samples)
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.
The array to set as the waveshaper curve. For linear curves array length does not make much difference, but for complex curves longer arrays will provide smoother interpolation.
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 number of inputs feeding into the AudioNode. For source nodes, this will be 0.
The number of outputs of the AudioNode.
Specifies what type of oversampling (if any) should be used when applying the shaping curve. Can either be "none", "2x" or "4x".
The duration in seconds of one sample.
The version number semver
Connect the output of this node to the rest of the nodes in series.
import { Destination, Filter, Oscillator, Volume } from "tone";
const osc = new Oscillator().start();
const filter = new Filter();
const volume = new Volume(-8);
// connect a node to the filter, volume and then to the master output
osc.chain(filter, volume, Destination);
connect the output of a ToneAudioNode to an AudioParam, AudioNode, or ToneAudioNode
disconnect the output
connect the output of this node to the rest of the nodes in parallel.
Get the object's attributes.
import { Oscillator } from "tone";
const osc = new Oscillator();
console.log(osc.get());
// returns {"type" : "sine", "frequency" : 440, ...etc}
Returns all of the default options belonging to the class.
Return the current time of the Context clock without any lookAhead.
Return the current time of the Context clock plus the lookAhead.
Set multiple properties at once with an object.
import { Filter } from "tone";
const filter = new Filter();
// set values using an object
filter.set({
frequency: 300,
type: "highpass"
});
Uses a mapping function to set the value of the curve.
import { WaveShaper } from "tone";
const shaper = new WaveShaper();
// map the input signal from [-1, 1] to [0, 10]
shaper.setMap((val, index) => (val + 1) * 5);
The function used to define the values.The mapping function take two arguments:the first is the value at the current positionwhich goes from -1 to 1 over the number of elementsin the curve array. The second argument is the array position.
Connect the output to the context's destination node.
Convert the input to a frequency number
Connect the output to the context's destination node. See toDestination
Convert the incoming time to seconds
Convert the class to a string
import { Oscillator } from "tone";
const osc = new Oscillator();
console.log(osc.toString());
Convert the input time into ticks
