AutoWah connects a Follower to a Filter. The frequency of the filter, follows the input amplitude curve. Inspiration from Tuna.js.
import { AutoWah, Synth } from "tone";
const autoWah = new AutoWah(50, 6, -30).toDestination();
// initialize the synth and connect to autowah
const synth = new Synth().connect(autoWah);
// Q value influences the effect of the wah - default is 2
autoWah.Q.value = 6;
// more audible on higher notes
synth.triggerAttackRelease("C4", "8n");
The number of octaves above the baseFrequency the filter will sweep to when fully open.
The decibel threshold sensitivity for the incoming signal. Normal range of -40 to 0.
The base frequency from which the sweep will start from.
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.
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.
The number of octaves that the filter will sweep above the baseFrequency.
The duration in seconds of one sample.
The sensitivity to control how responsive to the input signal the filter is.
The version number semver
The wet control is how much of the effected will pass through to the output. 1 = 100% effected signal, 0 = 100% dry signal.
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
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.
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"
});
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());
