Why don't you go to a live classical concert, Carlos, to hear what that really sounds like?
(And yes, we have debated the video thing ad nauseam, nothing to add.)
Next time that you are at classical music concert, check out where the microphones are positioned. They are in close proximity to the instruments and not out in the audience. The microphones are positioned in such a way to capture the full range of the instruments and/or vocalist. That is the sound that is being reproduced and not the comb-filtered sound at your seats.
Here are some more basics for you: One reason higher frequency sounds decay more rapidly over distance is due to the phenomenon of absorption. Higher frequency sound waves are more easily absorbed by the medium through which they travel, such as air or solid materials.
