title: How to play opus audio in Internet Explorer
body: <p>How can I play opus audio in browsers which are old or not compatible with the audio format.</p>
  
  <p>At the moment I serve the audio link in a html5 <code>&lt;audio&gt;</code> tag which works in Firefox and Chrome but it does not in IE, any version.</p>
  
  <p>I have read about opus.js and opusenc.js which is a JavaScript port of the opusenc tool, which in turn is part of the opus-tools collection, created with Emscripten.</p>
  
  <p>Do you know whether is it possible to play opus audio files using any of these JS in incompatible browsers?</p>
