An apparatus and method by which sound files may be modified within a gaming device to coincide with one or more game events. In one embodiment, a sound file is played in a first manner when the previous spin of slot machine reels does not produce a win for the player. The sound file is played in a second manner, however, if the previous reel spin does produce a win. In another embodiment, a sound file is played in a first manner when the current reel spin does not produce a win. The sound file is modified in mid-play, however, if the current reel spin does produce a win. In a further embodiment, the sound file is modified differently in mid-play if the current reel spin does not produce a win.
