Fairly basic
I thought the preloader looked better than the soundboard. Nice large choice of sound-bytes, but I didn't really think it was anywhere near as good as it could have been. For a start, you could have put the buttons on 2 pages, so that it wasn't so cramped. Secondly, it is possible via AS to stop each sound when you press a new button (without having to click the stopAllSounds button.
So... kinda nice work, but could definitely have been better.
