The present invention provides an apparatus and method by which sound files may be modified within a gaming device to: (i) coincide with one or more other sound files; (ii) coincide with one or more game events; or (iii) to produce a melody or song. The gaming device includes various processors and memory storage devices that control a sound card. The sound card stores sound files having truly synthesized sounds or true sound recordings. The output sample rate of one or more sound files is pitch-shifted to produce a sound having a higher or lower pitch and that lasts for a shorter or longer length of time, respectively.
