Apple has recently added support for Dolby Atmos (which they call Spatial Audio) to its streaming service and it can simulate the surround sound experience on headphones.
I have a collection of music remixed to Dolby 5.1 and I was wondering how I could convert it to alac files that I can import into the Music app on macOS and listen to with this simulated surround sound effect.
I have tried converting it to alac files with 6 channels, but I can't even import these files into the Music app. I'm happy to buy software that is capable of doing this conversion (from Dolby or otherwise) if that is necessary. I just have no idea how this can be done and I'm not finding much information online.
