Systems and methods provide for the creation of vehicle sound fonts, for utilizing the vehicle sound fonts to augment the engine sounds of a vehicle, and for establishing a network for sharing and controlling the playback of vehicle sound fonts and other media. The systems install in automobiles and play simulated engine sounds of other recorded vehicles in a controlled manner synchronized with the engine spark frequency of the playback vehicle. Automobiles with these systems may network together to share media and to coordinate playback in a synchronized manner among all vehicles of the network.
