Hello,
After the albums "Blue Banisters" and "Chemtrails Over the Country Club" released in 2021, Lana Del ray returns with a new album "Did you know that there's a tunnel under Ocean Blvd".
https://i.redd.it/pln7a1cfpmsa1.jpgThe comparison concerns the Qobuz, Apple Dolby Atmos, and white and black vinyl versions. For vinyl records, can the colour influence the sound?
Let's start with the comparison of the dynamics, with as shown in the graph below, the digital stereo version with its DR7, followed by the vinyl with its DR10, and in first place the Dolby Atmos version with a DR13. Dolby Atmos is more and more often the version with the least dynamic compression.
https://i.redd.it/8spvhzqgpmsa1.jpgConcerning spatialization, the mix favours the front channels and sends in the surround channels ambience and reverberation as shown in the graph below. The "A&W" track is the most worked on with a more spatially distributed musical placement.
Specialization for the albumSpatialization is now available for each song.
Concerning the comparison of vinyl recordings, the graph below represents the comparison of the surface noise between 2 tracks, with the white curve representing the white vinyl record and the blue curve representing the black vinyl record. It can be seen that the blue curve remains below the white curve, with differences of up to 5dB, so the surface noise will be lower on the black vinyl record, which is audible when listening.

To get your own idea of the different versions, you can find the extracts and all the measurements HERE.
Enjoy listening
