I'm also wondering if the final release will bring changes to the audio, depending on what basis the demo was built. Yeah, the replay cameras from the trackside, not those you can race from. The overall sense of space is diminished over the Large Theatre setting in particular from the PS3 games. Interestingly, there was no dynamic range setting for the audio in the demo. Same, with 3D audio over headphones. I also only had the option of stereo or 7.1, and I think the 7.1 mix worked OK with my 5.1 downmixer. I tested both anyway and my opinion of the sound stands regardless. I'd still suggest everyone check their settings match their hardware.
