title: Record Audio Stream from getUserMedia
body: <p>In recent days, I tried to use javascript to record audio stream.
  I found that there is no example code which  works.</p>
  
  <p>Is there any browser supporting?</p>
  
  <p>Here is my code</p>
  
  <pre><code>navigator.getUserMedia = navigator.getUserMedia || navigator.webkitGetUserMedia ||
                           navigator.mozGetUserMedia || navigator.msGetUserMedia; 
  
  navigator.getUserMedia({ audio: true }, gotStream, null);
  function gotStream(stream) {
  
          msgStream = stream;        
          msgStreamRecorder = stream.record(); // no method record :(
  }
  </code></pre>
