Display total timing in Html5 audio

http://ift.tt/1zOBAhH

I am used audio "preload="none" from above website. I want to display the "total time" like other "auto play and loop". If i use the other options like "loop" the time will be displayed. But I want to display this option in "preload="none". Is it possible?? Any one help me?

This is my Html Code:

<audio src="/mp3/juicy.mp3" preload="none" />

Script:

<script>
  audiojs.events.ready(function() {
    var as = audiojs.createAll();
  });
</script>
