That might be the easiest thing to try first.
possibly. there is one thing on the homepage that strikes me as odd, however:
"Ambi.decode~ decodes an ambisonic encoded sound field to a user-defined speaker array of up to 16
channels (more can be added by using more than one ambi.decode~ object). Messages control the
speaker layout, global gain, mono/spatialized balance, and decoding order weights."
i don't understand how one could just use two independent decoders and still arrive at an optimum
decoding result. it's not clear how the decoder works, and i'm not sure it's really
state-of-the-art... others may be able to comment.
You'd certainly want to look at doing some manual optimisation with multiple decoders, which might
be as simple (and time consuming!) as just tweaking things by ear or might involve a full scale
optimisation using something like Bruce Wiggins' heuristic approach.
check out the BLaH paper "is my decoder ambisonic?" for some of the pitfalls and a list of
known-good decoders.
But do be aware that the excellent work that has been done for these papers by Eric, Richard and
Aaron is (currently (that I'm aware of)) only for first order decoders and domestic sized rigs.
Ideally I would like to have 8 (maybe more) speakers that I could
configure in various different ways.
for larger audiences than, say, 5-10 people, i would recommend a third-order horizontal-only ring
of eight if you are looking for proper localisation. a cube in my experience is problematic for
more than one listener, unless all you want is envelopment.
Agreed.
