OscillatorNode: detune property
The detune property of the OscillatorNode interface is an a-rate AudioParam representing detuning of oscillation in cents.
[!NOTE] Though the
AudioParamreturned 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).
// 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();
