A slot machine, gaming method, and program product are provided to dynamically display visual and audio content to be played in synchronization with a music track. A digital signal processor performs frequency analysis of background music as it is played, and identifies musical beats to create beat events. The beat event is used to trigger additional presentation elements such as visual effects, sounds, and lighting on the beat of the background music. Spectral content information from the frequency analysis is used to create dynamic background graphics.
