Is it possible to play a sound effect over the background music without cutting off the background music? Because new mp3 files cut off the previous.

You might be able to play a WAV without it cutting it off an MP3, but you can't play two MP3s at the same time.

It's probably possible to have multi-track audio though (bear in mind this needs to work via a web browser too) - something to think about for Quest 5.1 maybe.

I thought about trying the WAV idea.I'll give that a shot first.

Hey hey hey!!! WAV WORKS! =D
