UMX (Unreal Music Package) is a container format used by the Unreal Engine to store music tracks, typically encapsulating tracker-format audio data such as S3M, XM, IT, or MOD. It allows game music to be packaged and referenced alongside other Unreal engine assets. It is primarily used in games built on the Unreal Engine 1 and 2 for background music playback.
