<p>{{APIRef("Web Audio API")}}</p>

<div>
<p>The <code>MediaElementAudioSourceNode</code> interface represents an audio source consisting of an HTML5 {{ htmlelement("audio") }} or {{ htmlelement("video") }} element. It is an {{domxref("AudioNode")}} that acts as an audio source.</p>
</div>

<p>A <code>MediaElementSourceNode</code> has no inputs and exactly one output, and is created using the {{domxref("AudioContext.createMediaElementSource")}} method. The amount of channels in the output equals the number of channels of the audio referenced by the {{domxref("HTMLMediaElement")}} used in the creation of the node, or is 1 if the {{domxref("HTMLMediaElement")}} has no audio.</p>
