But why some old songs are in Dolby Atmos? Artists have a way to add Atmos to their songs without recording them again?
studios "remix" and "remaster" tracks all the time. in the original studio recording, they would have used multiple microphones, and if those different audio streams are available they can be used to produce different final tracks with different intended effect.
sometimes its effective. most of the time it seems a mess.
Don't think they could have made this more confusing if they tried. Having read several posts and articles I still have no idea on the difference between Atmos and Spatial.
Similarly the difference between Automatic and Always On. Surely only Atmos tracks can be played in Atmos so what benefit is Always On over Automatic? Is Automatic just a gimmick to make those of us who paid out for AirPods think we're getting something better than everyone else?
atmos and spatial are both trademarks. one belongs to dolby, the other to apple. both are technology that has to do with surround sound. atmos content requires compatible downstream technology to properly reproduce the surround effects. spatial is apple's compatible downstream tech.
Neither Automatic nor Always On will "force" surround sound effects when it is not available in the content. apple will not automatically upmix something to surround. the difference only matters when a track is available in both atmos and non-atmos. the implication is that apple's spatial-compatible devices are optimized for playing atmos stuff and will choose it when available... whereas other
unrecognized devices may not play atmos content very well, so they let you pick which track you want to play.
It is absolutely criminal that they don’t have any Radiohead songs that support Dolby Atmos yet
the question is whether radiohead has or intends to produce their music in multi-channel? to my knowledge, they have never released a multi channel SaCD or DVDa. they deliver vinyl if people want (theoretical) higher resolution, and they may offer hi-res or lossless digital files too. but never surround stuff, so thats their decision
