Created attachment 278133
  --> https://bugs.webkit.org/attachment.cgi?id=278133&action=review
an mp3 where I experience the issue

AudioContext.decodeAudioData() returns double correct duration and samples array half filled with silence

My file is 30 seconds long - I'm told it's 60 seconds long on iOS and receive a samples array with the last half all garbage silence values.

I've noticed this in my project above. It works correctly in Firefox and Chrome.
