title: Play MP3 file stored as blob
body: <p>Put simply, I'd like to play a blob MP3 file in Firefox.</p>
  
  <p>I have access to both the blob itself: <code>blob</code> (sliced with mime type <code>audio/mpeg3</code>), and its URL: <code>blobURL = window.URL.createObjectURL(blob)</code>.</p>
  
  <p>I have tried with:</p>
  
  <ol>
  <li><p>an HTML5 audio player:</p>
  
  <pre><code>&lt;audio controls="controls"&gt;
      &lt;source src="[blobURL]" type="audio/mp3"&gt;
  &lt;/audio&gt;
  </code></pre>
  
  <p>but I get a warning in Firebug telling me that Firefox cannot read files of type <code>audio/mpeg3</code>.</p></li>
  <li><p>multiple audio player libraries (<a href="http://www.schillmania.com/projects/soundmanager2/">SoundManager</a>, <a href="http://www.jplayer.org/">JPlayer</a>, etc.), but none seem to allow blob URLs as input.</p></li>
  </ol>
  
  <p>Am I doing it wrong? Or does anyone know a workaround or a library that can play MP3 files from blobs?</p>
