I find arguing about sound to be strange, because unlike realistic visuals, realistic sound doesn't seem practical. When I play an F1 game, I don't want to have to wear earplugs.
We've read about the techniques and technology used to record the sound in DC. But, just as important is the equipment reproducing the sound in your living room. I wouldn't be surprised if the range of audio equipment being used by different posters here was similar to black and white SD to top-of-the-line 4K displays.
I personnally have a surround sound system with subwoofer, but I'll often play with $20 earphones so I can have it loud at night. Obviously, there's a substantial difference, but I don't blame the game designers when my cheap earphones sound a bit tinny.
