title: "Noisy Tabs" in Google Chrome- Detecting if sound is playing
body: <p>Google Chrome recently introduced the feature that allows users to tell what tab is making that <a href="http://chrome.blogspot.com/2014/01/everyone-can-now-track-down-noisy-tabs.html">"Noisy sound"</a>. What i'm interested in finding out is if this new feature allows <code>chrome extensions</code> to detect if a tab is making a sound.</p>
  
  <p>There is no documentation of any similar feature on the <a href="https://developer.chrome.com/extensions/tabs">chrome.tabs</a> developer page. Is there a way that you would be able to detect if a sound is playing (Without taking a "guess" based off of the content of the page i.e if the page contains <code>mp3</code> or video content)</p>
