I've been testing with some sounds last time and i got pretty nice sound of F1 BMW - it's working on standard LFS sound engine - i mean there is no car sound mixer or any 3rd party programs to emulate that sound. I used LFS Recorder to get nice smooth camera and then i put video from LFS Recorder and audio together in Windows Media Player. It sound bad from cockpit view or when TC is enabled - and more than one car with that sound at the same time is disaster.
