**Only works with ATS v1.39** Proudly introducing the Detroit Diesel 60 Series Sound & Engine Pack. All sounds were recorded from a Freightliner FLD120 with 60 Series engine fitted with straight exhaust and muffler with approximately 6 onboard perspectives including microphones mounted at the engine, exhaust and in the cabin. The sound setup features custom attenuation curves for the engine and exhausts meaning that the volume of each sound source can be heard differently at various distances, or when the vehicle passes the camera. This pack only contains engines sounds. No other sounds are included. A number of engines are included that I have carefully designed with references available online.
