Abstract: A gaming machine for conducting a wagering game includes selective application of surround sound. The selective application of surround sound allows certain key gaming events to be emphasized over other gaming events. The surround sound may be varied to produce certain effects, such as a tactile effect and a gradual building up of suspense and anticipation that increases player excitement and enjoyment. A surround sound decoder may be added in some embodiments to convert monophonic and stereo wagering games into surround sound. The surround sound may be implemented as true surround sound or as virtual surround sound.
