Hey Curtis! Thanks! Let me see if I understand what you're saying.
2. If I calibrate my system such that "0db" now equals a different loudness (db) with a given signal,
I'm afraid this may complicate the issue. Let's assume for simplicity that I have calibrated my
loudness level, and that there was no change from the system's default loudness at 0db. Let's
just assume that the system was already giving me an accurate 75db test signal at 0db. Lucky me.
I think this will help simplify my question. If I'm misunderstanding some aspect of this, please
correct me.
As an aside: I'm not really interested in matching my volume knob's scale to some external reference
such as THX or other, per se. I just turn the volume up until it sounds good. (almost everything I put in the movie player seems to have it's own standard of loudness anyway, so I just compensate the old fashioned
way by using the knob.)
