@thespeakerdude Am I correct to assume that Dolby is counting on the listener to use time alignment algorithms in the everyday playback system? The difference in original mixing position and final listening position is probably about 5 feet difference in a typical room. You saying the sound is dominant corresponding to the L,C,R direct sound is interesting because in 5.1 the L,R, surround speakers play a bigger part and in music sometimes a critical part if the mixer is willing to take chances. Based on the best mixed Atmos music I've heard it really sound like a big stereo mix and the brave mixers were wearing the same hat as the early stereo mixers (Beatles) who panned hard L,R info commonly. Active speakers have different time arrival info than passive systems if Dolby does not assume DSP in every system the emperor has no clothes, if you know what I mean. Object oriented sound panning info. works no matter what the acoustic environment.
This is a great example of the silliness that audiophiles live under. They worry about time alignment to within ½ inch but active passive circuits have at least 4 milliseconds of latency in the original recordings if there are digital and passive circuits involved, there is no way to see or hear that much time differences because it is invisible to the post production mixer on movies or live recordings.
