Totally agreeThe sound of the bad guy smashing into a light fixture comes from the height speakers, which is pretty cool. But those speakers then go silent for the rest of the scene and the majority of the movie. A better Atmos mix would keep those speakers active with atmospheric and ambient noises, reflected sounds, and other effects to create a consistent bubble of sound around the listener.
Ahhhh, yes, most likely you are right. Thanks for clearing that up for me.There were other upmixers prior to DSU and Neural:X that could expand a 5.1 or 7.1 soundtrack to additional speakers. DTS Neo:X and Audyssey DSX could derive Front Wide channels between the front mains and surrounds. Neo:X and Dolby Pro Logic IIz could also create two Front Height channels above the front mains. That's probably what you're thinking of.
Dang.. :-(Keep in mind that these upmixers do not know what's going on in the video content of the movie/game or know what specific sound effects are supposed to be. They derive extra speaker locations using phase correlation. The majority of audio that gets pushed to the height speakers are ambient sounds and reflections. If a specific sound effect was mixed in the ground channels, it's most likely to stay there. However, as I mentioned earlier, Neural:X is more aggressive with pushing some sound effects to the heights than DSU is.
They should be trying to invent "Smart Upmixers" that even though wouldn't work for all scenarios/scenes it could at least have trigger sounds (for instance a helicopter and airplanes, birds, etc.. makes extremely unique sounds) and when it hears that it knows it needs to push that to the ceiling. As helicopters/planes are never on the ground, and even when they are, they would fill the sky with their sound too. Something like that.
Apply that to other possible sounds too. Issue is, is somethings like a light bulb smashing is not always in a unique sound/position so, the adaptive AI couldn't ever fix that I guess. But at least its a start. And eventually get to Smart Upmixers with adaptive AI that indeed try to literally "watch" your movie and figure out what needs to go where.
