Pro DJ here... Agree with the rest of your comment except for... "Where vision shines is distinguishing where the signal comes from."

Suggest closing your eyes and having someone else snap their fingers around you, you'll know immediately where that sound came from. This is accomplished by your mind differentiating the slight time difference between when your left and right ear register the noise as well as the volume difference.

This innate ability can be developed by DJ's to take two songs playing at different speeds and speed or slow them down to match. This is called "beat matching" and before software made this more accessible (aka more automated) it was the key skill necessary for DJ'ing as it allows seamless transitions between songs.

I still find your comment insightful and interesting, I just had to nitpick that one part.

Cheers
