title: Embed aac (m4a) file into HTML
body: <p>I'm searching for the best up-to-date way to embed a m4a file into HTML. I want the standard controls to hide and replace them with my own controls. The control of the volume through JavaScript for fade in and fade out and the detection if the QuickTime plugin is installed is also important.</p>
  
  <p>Is there any JavaScript library that can do this? I was looking at apple.com, and they are using an html tag called 'audio-preview-url', but I couldn't figure out, how they embed the quicktime plugin for playing that preview url.</p>
  
  <p>Another </p>
  
  <p>thx,
