[GEEKY] Mac Sound Converter Utility
Apparently (not sure why yet) on Android, sound effects files using the OGG format work better than those using wav or mp3. It might be an AndEngine thing, I am not sure. Anyway, here's my result of half hour googling and experimenting for a reliable way to convert the files. I tried a bunch of things, and I finally settled on MediaHuman AudioConverter. Use it. It really works and is nice and simple.
