Whether this is desirable may be a matter of personal opinion. Palmer made his own comparison between DSU and Neural:X, which suggested that Neural:X was more aggressive and louder in panning sound effects to the height speakers. Still, I’d been curious to see what the competition did differently.Ī couple years ago, our site’s Michael S.
I didn’t have much complaint with this, as DSU generally does a good job. As such, in order to fill the height speakers in my room when playing a non-Atmos soundtrack, I had no choice but to use the Dolby Surround Upmixer (DSU). Its support for DTS upmixing was limited to Neo:6, which topped out at 7.1 channels of sound. In addition to being unable to decode actual DTS:X soundtracks (which defaulted to the DTS-HD Master Audio 7.1 core instead), the receiver also lacked the corresponding DTS Neural:X surround upmixer. My prior A/V receiver, the 2014 Denon AVR-X5200W, was a Dolby Atmos model released prior to the introduction of DTS:X. As part of my testing of the flagship Denon AVR-X8500H A/V receiver, I finally have access to all three of the competing immersive sound upmixer formats and was able to run a comparison to see exactly how they each work on a normal movie soundtrack.
