UMXblu is a utility that converts .UMX audio files into more easily readable formats. The .UMX file format is used by such popular games as Unreal Tournament and Deus Ex, for background music. Depending on the nature of the .UMX file, UMXblu will create a .it, .s3m, or a .xm file. These audio formats can be read by many applications, such as Player Pro or SoundApp, both available from MacUpdate. From there, you can even convert them into MP3, AIFF, or other formats.
