Could someone explain to me why there are two versions of soundtrack in Age of Empires 1? The first version is normal, more "old-sounding" and the second version is much more modern, much more clear-sounding and it is on YouTube and in UPatch HD. Why these two exist instead of just one like normally? Is it a matter of conversion of one sound file extention to another?
