absolutely essential.

essential for production, but not for listening.

not related to ambisonics. but dead useful.

not essential either. but very much recommended, as it contains
configurations to encode ambi into uhj stereo and back. for ambi use,
you want to include fons' separate "reverbs" package, which contains
some very nice b-format IR reverbs.

unrelated. it only does room and speaker correction.
it's probably my fault it got included in the list, since i once
described how to set up a diy ambi rig that includes drc. but that's
optional.

not strictly related, although helpful if you want to create your own IR
reverbs for jconvolver (or any other convolver), or if you want to
measure your room and/or speakers to perform DRC.

very helpful.

or any other lightweight alternative to ardour, if it's just about
signal routing.

if the question is "what do i include in my distro", then by all means
add all the software you mentioned. if the question is "what is the
minimum software stack i need to play around with ambisonics, then keep
it simple. in any case, you may want to include mplayer, as it's one of
the few players that does multichannel correctly (at least up to 8
channels) and will let you enjoy those soundfield recordings out on the
web without having to import them into an ardour session.
