title: Is there a way to have raw audio file inside .html file (without external files)?
body: <p>It might be a bit confusing.
  What I would like to achieve is to have my application work with just one .html file.
  Ofc, JS scripts and CSS I can easily put in there, no problem.</p>
  <p>The only thing that holds be back is the one tiny sound file, that I'm currently streaming from the internet. However it won't work, when there's no internet connection.</p>
  <pre><code>const notificationSound = new Audio(&quot;https://notificationsounds.com/storage/sounds/file-sounds-1142-inflicted.mp3&quot;);
  (...)
  if(soundOn){ notificationSound.play();}
  </code></pre>
  <p>I would like to include the raw data of the sound file in the .html file and then play it back.
  Is there a way to make it work?</p>
