Features: extremely detailed engine sound recorded every 100 rpms in 4+1 channel format with 4 synchronized microphones placed around the engine & the exhaust each interior switch, stick and warning tone recorded from the real truck and implemented into the game (e.g. blinkers, blinker stick, retarder stick, light switch, electric windows, etc.) many brand-new features have been implemented that aren’t part of the base mechanics due to a lot of programming and testing dynamic idle sound dynamic air-compressor sound that turns on and off like on the real Scania warning tones when turning off the engine without parking brake or with lights on multiple sound samples for one sound event (e.g. light switch with 3 different sounds, multiple engine start/stop sounds, different sounds for light-beam on/off, …) air sounds when engaging/disengaging the parking brake multiple sounds that are only triggered under certain driving conditions (e.g. engine brake engaging when shifting up for faster gear changes) many details such as key sounds when starting/stopping the engine, button sounds for raising/lowering the lift-axle, gear selector sound when shifting into reverse and much more Scania Opticruise gearbox shift and retarder sounds custom sound attenuation config for the truck cabin to have a very realistic sound insulation in the interior every sound placed in the correct 3D-position (interior + exterior) Test on v1.46
