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. -- FA
