Sound help

(Sorry got no clue where to post this >.>, since there is no sound forum. So sorry if its in the wrong place)

I need some help... Is there anyway to make custom... well, what to call it? Well, you know the sound files units use in-game (the whole file, attack, move, pissed etc). So is it possible to make your own files like that? and how if its possible? (I grabbed some sounds from WoW for some WoW models, but here is the problem >.>)

mmm im not sure..you might have to put them in the war3x.mpq or war3.mpq but i dont really know how to add sounds like those
