The SMU file format is a proprietary multimedia container developed by Electronic Arts for storing audio and musical data within their video game titles. It is primarily utilized for background music and ambient sound effects in legacy titles such as SimCity 3000, where it facilitates sequential playback of digital audio. As a legacy format, it is now largely obsolete and rarely encountered outside of retro gaming communities or emulation projects, posing minimal risk to modern computing environments.
