Accuracy is required if the production and reproduction environments
are independent. If they are not there's a lot of headroom.

There's a third method - Bruce Wiggins' Heuristic algorithm based methodology
(http://www2.derby.ac.uk/sparg-content/pdfs/bw_aes31_paper.pdf). This is, I believe, available in
his Wigware decoder plugins.There is also some work from China on genetic algorithm based design,
but I don't know what
Ah - I withdraw that about the Wigware decoders as the versions on Bruce's website are probably not
sufficiently flexible for your purposes, though the actual heuristic methodology probably is.

I know many people using ambisonics for eletroacoustic music and

The code that goes with the LAC2012 conference paper does 3D and
higher orders. In fact we used it to make a new 3rd-order Ambdec
config for CCRMA's 22 speaker array. Its written in MATLAB/Gnu
Octave, and it's not a lot of code. So plenty of opportunity for
tinkering with the goal functions.
