OscillatorNode.onended
The onended
property of the OscillatorNode
interface is used to set the event handler for the ended event, which fires when the tone has stopped playing.
Syntax
js;highlight[7]
Copy Code
var oscillator = audioCtx.createOscillator();
oscillator.onended = function() { ... };
Example
The following example shows basic usage of an AudioContext
to create an oscillator node. For an applied example, check out our Violent Theremin demo (see app.js for relevant code).
js;highlight[13,14,15]
Copy 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 = 3000; // value in hertz oscillator.start(); // start the tone playing oscillator.stop(5); // the tone will stop again in 5 seconds. oscillator.onended = function() { console.log('Your tone has now stopped playing!'); }
Properties
