The Web Audio API is used to control audio, which allows you to choose audio sources. You can also add effects; create audio visualizations, panning, etc.
Example
You can try to run the following code snippet to generate sound −
// use one context per document. Here we are creating one context for one document. You can create for other documents also var context = new (window.AudioContext || window.webkitAudioContext)(); // oscillator var os = context.createOscillator(); os.type = 'sine'; // sine is the default. So you can also use square, saw tooth, triangle os.frequency.value = 500; // setting the frequency Hz os.connect(context.destination); // connecting to the destination // starting the oscillator os.start(); os.stop(context.currentTime + 5); // stop 5 seconds after the current time
