The "gold standard" for this is the official documentation by SCS Software regarding the implementation. This is the definitive technical resource that replaced the old .ogg overwrite method and is what every "solid" modder uses today. The Core Technical Resources
Finding a formal academic "paper" on creating sound mods for Euro Truck Simulator 2 (ETS2) is tricky because most of the knowledge lives in developer documentation and community wikis rather than scientific journals.
Since ETS2 uses FMOD, understanding the "Events," "Parameters" (like engine_rpm or exhaust_load ), and "Buses" within FMOD Studio is the actual science behind the mod.
Experienced modders like Kriechbaum or Drive Safely often post technical breakdowns on the SCS Forums. These are the closest things to "peer-reviewed" papers in the modding community, detailing how to record high-fidelity engine sounds and loop them without seams.
