Dolby DD+ 5.1 & Psuedo Upmixing to Dolby Atmos 7.1.4. 5.1, Stereo & Tidal Atmos Binaural Compared
Just messing about taking the 5.1 DD+ raw pcm multichannel tracks, exploding them to their own panned channels and routing to corresponding 5.1 Bed objects (obeds) then routed to Dolby Atmos Renderer. Then diverges the object using size to spill into the heights and 7.1.4 space a bit, tweak eq as Dolby adds the perception of more low energy in the binaural mode. I monitor the 7.1.4 to Binaural output using near,mid and far Binaural render modes and also switch to the 2.0 fold down.
For comparison, the playback also runs Ashanti - Happy tracks in Stereo, a loopback headphone recorded Tidal Binaural (ie Dolby Atmos Binaural) and also the raw 5.1 being merged back into a 5.1 bus again to flick it to a 5.1 to Stereo foldown. By routing the stereo, 5.1 and Atmos to their own bus you see me flicking the DR monitor between each for A/B comparing on the fly. The Tidal Binaural Atmos is a DD+JOC played through Dolby Atmos for Headphones and loopback recorded. Ideally, I would have the AC4-IMS Tidal Binaural loopback recorded too, but at the moment it's only possible to loopback record from the phone either using Bluetooth A2DP SNK or via the headphone 3.5mm so wouldn't really be a good comparison with the purely digital files for stereo and 5.1 imo so left it.
