OscillatorNode.detune

This article needs a technical review. How you can help.

The detune property of the OscillatorNode interface is an a-rate AudioParam representing detuning of oscillation in cents.

Syntax

var oscillator = audioCtx.createOscillator();
oscillator.detune.value = 100; // value in cents

Note: though the AudioParam returned is read-only, the value it represents is not.

Value

An a-rate AudioParam.

Example

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).

// create web audio api context
var audioCtx = new (window.AudioContext || window.webkitAudioContext)();

// create Oscillator node
var oscillator = audioCtx.createOscillator();

oscillator.type = 'square';
oscillator.frequency.value = 440; // value in hertz
oscillator.detune.value = 100; // value in cents
oscillator.start();
