Revision 751457 of StereoPannerNode

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

<div>
<p>The <code>StereoPannerNode</code> interface of the <a href="/en-US/docs/Web/API/Web_Audio_API">Web Audio API</a> represents a simple stereo panner node that can be used to pan an audio stream left or right. It is an {{domxref("AudioNode")}} audio-processing module that positions an incoming audio stream in a stereo image using a low-cost equal-power <a href="https://webaudio.github.io/web-audio-api/#panning-algorithm">panning algorithm</a>.</p>
</div>

<p>The {{domxref("StereoPannerNode.pan", "pan")}} property takes a unitless value between <code>-1</code> (full left pan) and <code>1</code> (full right pan). This interface was introduced as a much simpler way to apply a simple panning effect than having to use a full {{domxref("PannerNode")}}.</p>
