After a bit more experimenting with AudioX, I've learned a few more things to clear up some of my confusions. Suffice it to say, the wiki is wrong when it says you only need one global AudioX object. At least for sounds effects anyway.
I would show you guys if you'd like to see, but I'm sure it can only really work as a .exe file, and I guess no one can download anything from MegaUpload, so if anyone has any better ideas on how I can upload it or something, I'll try uploading it there to try and show you. ^_^;;
