Some interesting ideas.
I hope they have only fallen foul of "the good day to publish bad news on"
(as the politicians say) effect, that is August is a bad month to publish
good news ... if you want comment / feedback on it.

Anyway, the two principle ideas seem to me, to be:

I
To use UHJ for first order distribution.
The consumer has no messy decoding to L/R if that is all they want.
But if the file is always the highest level of UHJ (3 or 4 channel) that
the original material will support then:
-users can do ambisonic playback
-users that start with L/R playback have the tempting thought that there
is 'more in the file' if only they go 'looking'

If this is a proposed standard, then I would say:
-BHJ (2 channel) should not be used
-SHJ (2.5 channel) should not be used (is bandwidth really a problem,
except for radio, these days?)
-THJ (3 channel) should only be used if the original material is three
channel
-PHJ (4 channel) is preferred

It would need some neat little standalone UHJ->-B-format decoders writing ...
(But that _could_ (unideally) progress whilst people beenfitted from just
L/R.)

Anyone able to comment on why the UHJ (2 channel) buttons on Ambisonia
were (?)never made active?
I presume a re-coding problem, but it would be interesting to know.


II
Yes, we are hitting our head on the ceiling with FuMa.
Personally, though, if we are to move on I would go for an infinite order
'file' format.
Otherwise before our bruised heads recover we will be banging the ceiling
again ....
But it needs doing.

(I say  " 'file' format " as it is a format for files, for streaming, .....)
