Fons,
I don't know how to compute the gain factors for 3rd order other than by
numerical methods. I'm aware that Moreau published the gains of (1.000, .862,
.612, and .305) but I don't know if those are correct or if there was a general
solution published. I'm willing to give the computation a try, using my own
crude methods (stylus and clay tablets), but I wouldn't be able to start
realistically until after the AES Convention.
It's certainly an interesting problem! Have you got some 3rd-order 3D Ambisonic
recordings to go with your Icosahedron?
i have a few, usually a combination of first-order soundfield and panned
third-order. contact me off-list if you're interested.
