<div class="summary">
 <p><span class="seoSummary">The <code><strong>ChannelSplitterNode</strong></code> interface, often used in conjunction with its opposite, {{domxref("ChannelMergerNode")}}, separates the different channels of an audio source into a set of <em>mono</em> outputs. This is useful for accessing each channels seperately, e.g. for performing <em>channel mixing</em> where gain must be separately controlled on each channel.</span></p>

<p>If <code>ChannelSplitterNode</code> always has one single input, the amount of outputs is defined by a parameter on its constructor and the call to {{domxref("AudioContext.createChannelSplitter()")}}. In case no value is given, it default to <code>6</code>. If there are less channels in the input than outputs, supernumerary outputs are silent.</p>
