Dolby Atmos is a minimum 7.1.4 channel surround sound format. Tidal Master is a high resolution two channel stereo streaming format competitive with WAV, FLAC and AAC which support high resolution audio of 24bit/96khz or higher, and is supposedly lossless but with smaller file sizes to accommodate streaming bandwidths. 360 Reality Audio is Sony’s proprietary multichannel audio format competing with Dolby Atmos, but is more geared towards headphones in which a virtual mix is created simulating speaker locations, and secondarily can play back multichannel audio over speakers on compatible home theater systems. Apple Music Spatial audio takes a 7.1.4 mix like Dolby Atmos and converts that to a headphone compatible mix in which the speaker locations are simulated similar to 360 Reality Audio.
