It's a comparison of height channel amplitude time histories of DSU and DTS Neural X from this article http://www.heise.de/ct/artikel/DTS-X...-3085326.html;
the caption is "Upmixer compared: DTS: X Neural (below) adds the opening scene of "Transformers: Age of Extinction" much more than Dolby effects to DSU as the waveform of the left rear height channel shows."
DTS Neural X was the clear winner, at least for Xformers AOE, where it's even way better than native Atmos:
"Almost a classic for Test all-round sound Upmixern is the opening sequence of "Transformers: Age of Extinction": On the Atmos track prevails here on the height channels silence - although spaceships fly into the picture, the camera standing under a waterfall, Dinosaurierer screech, a spaceship small satellite settles and at the end even from behind the right front flying a plane left.
Dolby Upmixer adds this scene actually only a few altitude effects - for example, when the waterfall can be seen. All in all, the result remains unsatisfactory but: When overflight of spaceships continue to do very little, the plane one hears only a little about the height speakers. Therefore, we were curious to see what DTS Neural: X delivers.
In fact, the DTS Upmixer lays neatly away from the first setting: spaceships and aircraft roar now clearly audible from the ceiling speakers. The sounds are not just louder than the DSU, but also clearer. But above all, like the scene with the waterfall: The roar is not only clearly audible, it also migrates to match the camera movement from the left to the right side. DTS Neural: X and DSU can be distinguished easily in a blind test."
This is really exciting if it's as typically effective for other movies; if I had to choose I'd gladly take a good upmixer over the ability to decode native content.
