That's all very nice to know. I only have two speakers and I know next to
nothing about ambisonics. I'm not a real user of this or any other
ambisonics library and I have no idea about the state and issues of HOA. I
also have no idea what's been modified and what's going on inside CEAMMC.
But anyway, lots of information has been spread here and that's great!

I had the idea one could just get 'hoa' from deken without having to get
all of ceammc or use their fork. Not that I have anything against
ceammc integrating it (and, for what I know now, actually "saving" and
"resurrecting" hoa), it's just that sometimes people want one specific
thing (in this case a dedicated ambisonics library) and would rather not
carry more than they needed. And ceammc as a library carries lots of stuff
on their own and also encompasses/includes other third party libraries
(such as hoa, cream, chaos and more stuff).

In a more critical sense, there's no 'ceammc' for any linux distribution in

So if there weren't so many issues that are now clear, I could see the
point and advantage of "resurrecting" hoa and bringing it to deken for all
platforms (including raspberry pis).

that'd be nice, the more the merrier :) Pd could use more ambisonics
objects. This is why I felt it was necessary to upload CICM-Tools to deken!
