title: Restrict audio playback to specified range
body: <p>Say I have an audio file that is 90 seconds long.</p>
  
  <p>I wish to load this audio file for user playback, but have the playback restricted between 10s-40s.</p>
  
  <p>What I am trying to achieve:</p>
  
  <ul>
  <li>Audio starts at 10s</li>
  <li>When audio ends, it resets to the 10s mark</li>
  <li>Audio ends at 40s</li>
  <li>Audio outside the range is inaccessible</li>
  </ul>
