title: Audio context not working properly on android
body: <p>I'm having this issue with android (either for android browser or chrome for android): getByteFrequencyData method returns 0 values. </p>
  
  <p>Some say that the Web Audio Api is not supported in android mobile devices (IOS does support it) but I have juste checked this <a href="http://caniuse.com/#feat=audio-api" rel="nofollow noreferrer">link</a>, where it says that chrome 49 support Audio Api. </p>
  
  <p>Some say that it is an old <a href="https://bugs.chromium.org/p/chromium/issues/detail?id=419446" rel="nofollow noreferrer">issue</a></p>
  
  <p>And some say that the problem comes from the media element, if you can load the media with XHR into a buffer and play it, it will <a href="https://stackoverflow.com/questions/27552704/android-chrome-39-getbytefrequencydata-returns-0-array">work</a> (I tested but it didn't work)</p>
  
  <p>I'm trying to make an audio visualizer working on android cordova by using Audio APi + Canvas
  Any help? </p>
