title: Embed mp3 in actionscript 3 doesn't work
body: <p>I have a problem with actionscript 3, especially when using the embed tag. I have this code:</p>
  
  <p><code>
  [Embed(source = "sound.mp3")]<br/>
  private static var soundClip:Class;<br/></p>
  
  <p>...</p>
  
  <p>var sound:Sound = (new soundClip()) as Sound;<br/>
  trace(sound.length);
  </code></p>
  
  <p>When I test the movie, I get the following output :  4501,923 Which is the sound.mp3 length in milliseconds. However, the original sound is 13.000 milliseconds.</p>
  
  <p>How can that be possible, can anyone help me please?</p>
  
  <p>Thank you.</p>
