The stop
method of the OscillatorNode
interface specifies the time to stop playing the tone. Its parameter is optional and defaults to 0
.
Syntax
oscillator.stop(when); // stop playing oscillator at when
Parameters
- when Optional
- An optional double representing the audio context time when the oscillator should stop. If a value is not included, it defaults to
0
. If the time is equal to or before the current audio context time, the oscillator will stop playing immediately.
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).
// create web audio api context var audioCtx = new (window.AudioContext || window.webkitAudioContext)(); // create Oscillator node var oscillator = audioCtx.createOscillator(); oscillator.connect(audioCtx.destination); oscillator.start(); oscillator.stop(audioCtx.currentTime + 2); // stop 2 seconds after the current time
