<p><span class="seoSummary">The <strong><code>Media.pause()</code></strong> method (part of the <a href="/en-US/docs/Web/API/MediaRecorder_API">MediaRecorder API</a>) is used to pause recording of media streams.</span></p>
<p>When a <code>MediaRecorder</code> object’s <code>pause()</code>method is called, the browser queues a task that runs the below steps:</p>
<ol>
<li>If {{domxref("MediaRecorder.state")}} is "inactive", raise a DOM <code>InvalidState</code> error and terminate these steps. If not, continue to the next step.</li>
<li>Set {{domxref("MediaRecorder.state")}} to "paused".</li>
<li>Stop gathering data into the current {{domxref("Blob")}}, but keep it available so that recording can be resumed later on.</li>
<li>Raise a {{event("pause")}} event.</li>
</ol>

<dd>The <code>MediaRecorder</code> is currently <code>"inactive"</code>; you can't pause recording if it's not active. If you call <code>pause()</code> while already paused, it silently does nothing.</dd>
