title: HTML5 Audio, Web Audio API, CORS and Firefox
body: <p>I have been trying to get this to run correctly so days now with no luck.</p>
  
  <p>I have created a custom audio player, that accesses an MP3 on a S3 Amazon server. The audio player has custom controls enabled by Javascript, and a Audio Visualizer made possible by the Web Audio API.</p>
  
  <p>Now the problem I am running into is this: Work fine on Chrome. Safari out right says it can't run the Web Audio API, but the audio will still play.  In Firefox, the entire thing shuts down. Click play... nothing.  I thought it was a CORS issue, so we set the proper headers on the server and still nothing.  BUT... if I deactivate the Web Audio API visualizer, then I can get the player to play just fine.</p>

  <p>Here is my jFiddle. I have separated the Audio Player controls Script from the Visualizer Script with comments so you can see how it will work in Firefox, and how it will NOT work in Firefox.</p>
  
  <p>I read somewhere that this issue that I'm running into MAY be a bug with Firefox.  I just want to make sure so that I can stop beating my skull over this.</p>
  
  <p>Could I put a call to CORS here?:</p>
