While many game companies went from [[FM synthesis]] or [[General MIDI]] in the early 1990s to enhanced CD audio and pre-rendered audio, many of the Epic Games used the less common system of [[Module file|module music]], composed with a [[Music tracker|tracker]], which used stored [[Pulse-code modulation|PCM]] [[Sampling (signal processing)|sound samples]] of musical instruments sequenced together to produce music. Epic had been using this technology for other games such as ''[[Jazz Jackrabbit (video game)|Jazz Jackrabbit]]'' and ''[[One Must Fall: 2097]]'', which allowed relatively rich music to be stored in files usually smaller than one megabyte.<ref>[https://books.google.com/books?id=m5exIODbtqkC&dq=%22epic+games%22+tracker+music+mod+unreal&pg=PA341 Game Development and Production] by Erik Bethke, page 341</ref> This technology allowed easy implementation of dynamic music for mood changes in ''Unreal''. The ''Unreal'' soundtrack was written by MOD music authors [[Alexander Brandon]] and [[Michiel van den Bos]] with a few selected tracks by [[Dan Gardopée]] and [[Andrew Sega]] ([[Straylight Productions]]). ''Unreal''{{'}}s music engine also supports CD audio tracks. The game also made use of the [[A3D|Aureal 3D]] technology.<ref>{{cite book |title=1394 Monthly Newsletter |url=https://books.google.com/books?id=N40wrMDs1GUC&pg=PA4 |last=Polishuk |first=Paul |date=December 1998 |page=4}}</ref>
