You're right - it's a very, very badly written article.
Not only does it conflate the Dolby Surround Upmixer (which Dolby Atmos AVRs also have, as an add-on extra), it even makes it worse by using the term "pure" Dolby Atmos - as if "pure" isn't a real word, as if there are two Atmoses, "pure" and "up-mixed". There aren't, as we've said and you now understand. There's Atmos, and then there's everything else.
Thanks for bringing it to our attention
Here's a full list of corrections. From the terrible web page
you don’t have to wait to experience the the (SIC) immersive, cinematic sound of Dolby Atmos thanks to “upmixing.”
Wrong, if you're upmixing you will NOT be experiencing the immersive, cinematic sound of Dolby Atmos! You'll be experiencing the (very good) immersive sound of the up-mixer called the Dolby Surround Upmixer.
THE DIFFERENCE BETWEEN SURROUND SOUND AND UPMIXED DOLBY ATMOS
There's no such thing. If it's upmixed, it's not Dolby Atmos, by definition.
Just like colourised Laurel and Hardy films were not actually colour. They are black and white, with lots of processing having been done to them, and you are seeing the synthesized results. The only difference is that the DSU processing is done in real time.
THE DIFFERENCE BETWEEN UPMIXING AND “PURE” DOLBY ATMOS
The quotes are wrong. This should read: "THE DIFFERENCE BETWEEN UPMIXING, AND DOLBY ATMOS".
“Pure" Dolby Atmos is only possible when source material is encoded (mixed and published) in Dolby Atmos technology. If you are looking at a Blu-Ray, it should be clearly labeled with the Dolby Atmos logo on the disc packaging.
With a “pure” Dolby Atmos mix, you are hearing sound exactly as the (human) sound editor intended it.
Quotes wrong again. Remove "Pure" from both sentences.
In order to upmix to Dolby Atmos, an algorithm in the receiver determines which sounds go to the Dolby Atmos channels based on frequency and phase correlation. Essentially, upmixing is a synthesized, yet very effective Dolby Atmos experience that draws from the original 5.1/7.1 mix.
False again. Should read: "In order to upmix using the Dolby Surround Upmixer to something which is a bit like but not Dolby Atmos, an algorithm in the receiver determines which sounds go to the HEIGHT channels based on frequency and phase correlation. Essentially, upmixing is a synthesized, yet very effective experience which is like
Dolby Atmos but it is not Dolby Atmos
, that draws from the original 5.1/7.1 mix.
