title: HTML5 / JS Audio: Real-time audio mixing possible?
body: <p>Does someone have an overview of the browser audio APIs situation today (Oct 2012)?</p>
  
  <p>Is it possible today to create synchronized realtime mixing of several (2 to 6) MP3 audio files? </p>
  
  <p>If not, are there any work going on (alpha, beta) that will make this possible?</p>
