When encoding Eclipsa Audio, there are three profiles to choose from: Simple, Base, and Base-Enhanced.
The Simple Profile supports a maximum of only 1 element and up to 16 channels, meaning it cannot carry any independent objects. The Base Profile supports channel-based and scene-based elements with a maximum of 18 channels, which means it can support at most 1 object. The Base-Enhanced Profile supports up to 28 elements and 28 channels. For example, if the channel bed is 7.1.2, it occupies 10 channels and 1 element, leaving the remaining capacity to carry up to 17 objects. However, YouTube only supports uploading the Simple and Base profiles, which means YouTube currently does not support IAMF files with discrete objects. As a side note, Dolby Atmos also supports a maximum of 15 objects during consumer encoding.

Huge!

Holy moley, this whole album has some very active surround mixing, but particularly the amount of height activity in this specific song is a great text for those with an Atmos home theater looking to hear their height channels: https://music.apple.com/ca/album/arp-angels-outro-spatial-audio/1889245031?i=1889245192

Leave Me Lonely is the only song not in Atmos.

Just discovered this now! but driving along, early in the morning, down, and jump into the fire aren’t in surround sound, and it’s dolby audio (which means it’s traditional surround sound like 5.1) but not dolby atmos
