Seems a bit misleading to call something ambisonic if all it will
do is 2d, so partial b-format to (square?) 4 channel.
Why not be more specific in the name so the limitation is clear.
This is just for qualification task. Later filter willl be extended.
It will not be applied as is in tree.
Ahh, OK.
A complicated subject.
Sanchit, in case you don't know, some of the people who were around at
the birth of ambisonics, plus ambdec author can be found on the list -
