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);
