Greetings to all Sursound list.
First of all, thanks for all this years supporting Ambisonics. We´re
a collective of audiovisual artists preparing for our next project.
We have been researching ambisonics for the last few moths, seeding
the possibility of it´s implementation. There are still some concerns
regarding workflow. Our initial idea is to keep signals / conversions
into the analogue domain.
erm?
For example, analogue panners. I´ve stepped
with very few B-format ideas on the internet, so I was wondering if
there´s a case considering simple A-format panners, before AB
converters. This eurorack module seems right for the task, right?:

"A-format" panning as you call it has nothing to do with ambisonics per
se, and the term frankly doesn't make much sense.
the module you mention is a simple amplitude panner.
so for your purposes, you might want to look into amplitude panning.
but this has none of the characteristics of ambisonics.
But height
information?. Are B-format panners somehow better? We know of the
multiple ambisonics ITB plugins available, but again, we love ancient
analogue qualities. Any info will be very appreciated, we´re really
exited about this & will love to share the results somewhere in the
near future. Best regards. Gino.
for height, you will need vbap, and it's totally insane to even consider
doing this in analog (just think of the operation to find the three
nearest speakers for a given direction).
unless it's actually pain you love, in which case you've struck a gold mine.
now you _could_ implement an ambisonic with-height b-format panner in
analog. likewise, i could have faxed you my reply in 2's complement, and
you could have OCR'ed it back into your computer. it's needlessly
complicated, a waste of resources, and unless the equipment is
constantly being re-calibrated to perfect accuracy, the result will be
so full of errors that it's pretty much pointless.
