Let me first by stating that I'm a Best Buy Employee, specifically in the Home Theater Department.
I'm also one of those people who does there homework when buying new equipment...or so I thought. However, after I discovered Audioholics, I then realize, that the homework I did, beyond pricing, was really just superficial; fluff pieces about the latest whatever. I now know different.
Ok, now that that is out of the way, onto my first post.
High Definition Sound.
Recently, I just sat down with a friend of mine, to talk about Hi-Res audio, specifically how a Sony soundbar product I sell (HTST9) really sounded great playing a HD sound file. My friend took the stance that there is no such thing as HD sound, and that, what I really heard and was responding to was, dynamic range, and not the "HD file". This discussion went on for a couple of hours, and it basically boiled down to this. using a CD as the baseline (44KHz; 16bit); that would encompasses most of what an average human ear can hear, which means that there is not much more past that standard for an ear to hear. So if music is recorded in a higher KHz or with more bit rate, it really wouldn't matter because the ear either can't hear it or distinguish it as better.
Is this true, there really is no such thing as High Definition music files. And the more important question, how do I educate my customers honestly about a product that can play HD music?
