This feature is well established and works across many devices and browser versions. It’s been available across browsers since July 2015.
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.
An a-rate AudioParam.
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();
