Some colleauges of mine do need a tool for coding and

high-order Ambisonic for their research. They are aiming for seventh
order, played back over sixteen loudspeakers. They are now planning to
implement this, using either JACK or LADSPA.
As I have some experience with linux audio, I got involved. So I am
seeking some advice and answers here. The first thing I would like to
know is: Does anything like this already exist?
No, and for some very good reasons.
Regardless of the JACK / LADSPA question, seventh order Ambisonics using
16 speakers is just ridiculous. Either it's horizontal only, and in that
case using 7th order is just a waste of resources and effort (3th order
will do all you want), or it's 3-D, and it that case 7th order requires
*much* more than 16 speakers.
AFAIK, nobody ever even worked out the equations for 4th order or above.
