OscillatorNode: detune property
Baseline Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since April 2021.
The detune
property of the OscillatorNode
interface is an a-rate AudioParam
representing detuning of oscillation in cents.
Note:
Though the AudioParam
returned is read-only, the value it represents is not.
Value
An a-rate AudioParam
.
Examples
The following example shows basic usage of an AudioContext
to create an oscillator node. For applied examples/information, check out our Violent Theremin demo (see app.js for relevant code).
js
// create web audio api context
const audioCtx = new AudioContext();
// create Oscillator node
const oscillator = audioCtx.createOscillator();
oscillator.type = "square";
oscillator.frequency.setValueAtTime(440, audioCtx.currentTime); // value in hertz
oscillator.detune.setValueAtTime(100, audioCtx.currentTime); // value in cents
oscillator.start();
