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.
Note: If a scheduled stop time occurs before the node's scheduled start time, the node never starts to play.
Syntax
AudioScheduledSourceNode.stop([when]);
Parameters
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 itscurrentTime
attribute. Omitting this parameter, specifying a value of 0, or passing a negative value causes the sound to stop playback immediately.
Return value
Exceptions
InvalidStateNode
- The node has not been started by calling
start()
. RangeError
- The value specified for
when
is negative.
Example
This example demonstrates starting an oscillator node, scheduled to begin playing at once and to stop playing in one second. The stop time is determined by taking the audio context's current time from AudioContext.currentTime
and adding 1 second.
context = new AudioContext(); osc = context.createOscillator(); osc.connect(context.destination); /* Let's play a sine wave for one second. */ osc.start(); osc.stop(context.currentTime + 1);
