Yes, my intended use is for real-time encode and decode on the spot. All the spatial information is stored parametrically, i.e. mono sounds + x,y,z coordinates. Also, forgot to say, the rig is 3D with 34 speakers, 26 above ground and 8 below ground forming a kind of sphere, but it’s not really symmetrical to the center listening position (it’s the sonic lab of SARC). best, Miguel _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound
