 <p>The Web Audio API does not replace the {{HTMLElement("audio")}} media element, but rather complements it, just like {{HTMLElement("canvas")}} coexists alongside the {{HTMLElement("img")}} element. Your use case will determine what tools you use to implement audio. If you want to control playback of an audio track, the <code>&lt;audio&gt;</code> media element provides a better, quicker solution than the Web Audio API. If you want to carry out more complex audio processing, as well as playback, the Web Audio API provides much more power and control.</p>
