[Javascript] Intro to the Web Audio API

An introduction to the Web Audio API. In this lesson, we cover creating an audio context and an oscillator node that actually plays a sound in the browser, and different ways to alter that sound.

var context = new window.AudioContext() || new window.webkitAudioContext(),
    osc = context.createOscillator();

osc.frequency.value = 440;
osc.connect(context.destination);
osc.type = "sine";
// uncomment the following line to make noise!
// osc.start();
