Avec l'aide de Peter Jackson, Giles Martin a pu utiliser un nouveau logiciel permettant maintenant de "démixer" des fréquences enregistrées à l'origine sur 4 pistes.

Giles Martin had previously expressed interest in remixing the Beatles' pre-Sgt. Pepper albums via special "demixing" technology developed at Abbey Road Studios, but wanted to wait until the software improved enough to be used in such a project.
Speaking to Rolling Stone in July 2021, Martin said that the software was "getting a lot better" and that he was "constantly looking at how we could approach it if I ever get to [remix] Revolver or Rubber Soul, early albums, which a lot of people want me to do".
In October 2021, Martin told Super Deluxe Edition: "I don't think it's ready at this moment in time", but noted about Revolver : "There's not as much bouncing down on Revolver as there is on Pepper. There's not that many instruments, it's not that complex."
[On "Taxman"] I can take off the guitar, I can take off the bass, and then I can even separate the snare drum and kick drum as well. And they sound like the snare drum and kick drum. There's no hint of guitar on there (even though they'd been baked together on the master tapes). And I don't know how it's done !
It's like I'm giving them a cake and they're giving me flour, eggs, and milk and some sugar.
– Giles Martin on the "demixing" technology used to remix the album
In late August 2022, Martin confirmed via Twitter that Revolver would receive a remix, with a further tweet hinting at an additional surround sound mix.
The reissue was officially announced on 7 September 2022.
Martin confirmed that the "demixing" technology had improved considerably by that point, and credited the work done by Peter Jackson's audio team in the development of The Beatles: Get Back for making the new remix possible.
To promote the reissue, the new mix for the album's opening track, "Taxman", was released as a preview.
