MDN wants to learn about developers like you:


The stop() method on AudioScheduledSourceNode schedules a sound to cease playback at the specified time. If no time is specified, then the sound stops playing immediately.

Each time you call stop() on the same node, the specified time replaces any previously-scheduled stop time that hasn't occurred yet. If the node has already stopped, this method has no effect.

If a scheduled stop time occurs before the node's scheduled start time, the node never starts to play.




when Optional
The time, in seconds, at which the sound should stop playing. This value is specified in the same time coordinate system as the AudioContext is using for its currentTime attribute. Omitting this parameter, specifying a value of 0, or passing a negative value causes the sound to stop playback immediately.

Return value



The value specified for when is negative.


ac = new AudioContext();
os = ac.createOscillator();
/* Let's play a sine wave for one second. */
os.stop(ac.currentTime + 1);
