Known browsers to work well in:

  • Firefox 4-27 (Windows 7, Windows Vista, Mac OS X)
  • Google Chrome 18+
  • Safari 5.1.5+

Browsers that suck at performance or fail to run the code correctly:

  • Firefox 4+ (*nix versions of Firefox have audio lockup bugs) - Retest this
  • Firefox 28+ (Web Audio API creates 500 ms or greater latency, forced by Firefox)
  • Opera (Crashes + Slow + Graphics Glitches) - Retest this
  • Safari 5.1.X (Below 5.1.5) (Slow or crashes)
  • IE 1-8 (Cannot run)
  • IE 9-10 (Slow, No native audio support (Requires flash bridge in the audio lib))
  • IE 11 (No native audio support (Requires flash bridge in the audio lib))
  • Firefox 1-3.6 (Slow)
  • ALL VERSIONS OF MOBILE SAFARI AND OPERA (Stop pestering me, iOS just CAN'T run this well.)
