Because Ambisonics is a technique to create a sound field in a small sweet spot, interaction with the room should be avoided, especially at low frequencies. So the omnidirectional pattern is probably the worst. > We have a lot of discussion on decoding coefficient, decoding > directivities (in phase, max Re etc) but not on the best solution for > the transducer directivity. Or room treatment (passive and active); directivity is one way to avoid problems with the room. > I hope you can solve my uncertainty. > > Thanks > Serafino I think it's a matter of finding a trade-off; even with directive speakers, room treatment is important to avoid at least first reflections. And in a large room, where no treatment is possible, directive speakers should minimize problems. -- Marc _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound - unsubscribe here, edit account or options, view archives and so on.
