Trucker AUX plays any audio from your PC (Spotify, YouTube, a Discord call…) through virtual speakers inside your truck's cab. The speakers sit where real ones would, and the sound follows your head: look out of the side window and the door tweeter is now behind your ear.
Virtual audio cable driver required.
Features
Real head position: HRTF spatial audio synced with the in-game head. With the bundled camera plugin it also follows the game's look into turns and toward the blinker.
Any audio source: anything that can play into a virtual audio cable. Works with ETS2 Local Radio.
Ready presets for a long list of ATS and ETS2 trucks, switched automatically when you change trucks. Cabs of one model are told apart by the fifth-wheel position, and your own trucks are remembered by plate.
Visual editor: drag speakers on top and side views. Speaker types with crossovers: full range, small full range, tweeter, midrange, mid-bass, subwoofer.
Cab controls: keyboard or controller bindings to try preset variants while driving, plus Volume Up / Down and Mute.
Like a car radio (togglable): mutes while the engine or the electrics are off. A separate preset for the pause menu, with a smooth fade.
Extra layers: a second audio source from another seat at once, e.g. Discord through the "Hitchhiker" preset, like a passenger talking. Multiple virtual cables required.
Loudness matching between presets with different speaker counts.
