Multi Channel Atmos

[simoncn]

The FLAC specification supports the following channel assignments:
1 channel: mono
2 channels: left, right
3 channels: left, right, center
4 channels: front left, front right, back left, back right
5 channels: front left, front right, front center, back/surround left, back/surround right
6 channels: front left, front right, front center, LFE, back/surround left, back/surround right
7 channels: front left, front right, front center, LFE, back center, side left, side right
8 channels: front left, front right, front center, LFE, back left, back right, side left, side right

MinimServer shows these in the #AudioChannels special tag as follows:
1 channel: 1
2 channels: 2
3 channels: 3
4 channels: 4
5 channels: 5
6 channels: 5.1
7 channels: 7
8 channels: 7.1

There is an inconsistency for 7 channels, which should probably be shown as 6.1 because it includes LFE.

Other "nonstandard" channel assignments can be used in audio files and there is an industry standard file tag WAVEFORMATEXTENSIBLE_CHANNEL_MASK to specify these assignments. MinimServer does not currently support this tag but support could be added if needed.

Do your Dolby Atmos files conform to any of the FLAC standard assignments listed above? If not, do they use the WAVEFORMATEXTENSIBLE_CHANNEL_MASK tag to specify the channel assignment?
