i am new at this and I just figured they are .WAV files
i went on the inetrnet did a google of free wav files
there are a zillion sites out there, and i downloaded and saved them to the sound file under tDirector.
then they are available to you .
also you can put songs in too, tell the prgram to play a song during the game, mix them up and have fun.
i put some mp3 songs into the sound events and thats pretty cool too.
Ialso throw in some wav files at random, just for entertainment.....
mess around and have fun with it...md ( like I said I am new to it and if I figured how to do it anyone can)
