title: Can't get Web Audio API to work with iOS 11 Safari
body: <p>So iOS 11 Safari was supposed to add support for the Web Audio API, but it still doesn't seem to work with this javascript code:</p>
  
  <pre><code>//called on page load
  get_user_media = get_user_media || navigator.webkitGetUserMedia;  
  get_user_media = get_user_media || navigator.mozGetUserMedia;
  get_user_media.call(navigator, { "audio": true }, use_stream, function () { });
  function use_stream(stream){
      var audio_context = new AudioContext();
      var microphone = audio_context.createMediaStreamSource(stream);
      window.source = microphone; // Workaround for https://bugzilla.mozilla.org/show_bug.cgi?id=934512
      var script_processor = audio_context.createScriptProcessor(1024, 1, 1);
      script_processor.connect(audio_context.destination);
      microphone.connect(script_processor);
      //do more stuff which involves processing the data from user's microphone...
  }
  </code></pre>
  
  <p>I copy pasted most of this code, so I only have a cursory understanding of it. I know that it's supposed to (and does, on other browsers) capture the user's microphone for further processing. I know that the code breaks on the <code>var audio_context = new AudioContext();</code> line (as in, no code after that is run), but don't have any error messages cause I don't have a mac which is required to debug iOS Safari (apple die already >_&lt;) Anyone know what's going on and/or how to fix it?</p>
  
  <p>e: forgot to mention that I looked it up and apparently I need the keyword "webkit" before using Web Audio API in Safari, but making it <code>var audio_context = new webkitAudioContext();</code> doesn't work either</p>
