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();
