Quite a challenge I'd say, in particular if those voices have to come near to the listener. With most the speakers at larger distance you'll need a room that is quite 'dead' by itself, and then synthesize the interaction of a virtual room and the voice. Would there be any way to move the side and back speakers closer ? > Fons - when you say a "corner case" you're saying that 6 speakers aren't > enough?

No, I means that when comparing VBAP to 2nd order AMB panning (in a more convential setup - with the listener closer to the center) the difference between the two would be quite clear, with each system having its distinct pros and cons and probably no clear preference. As order goes up AMB panning will concentrate more energy in the nearest speakers and the two systems converge, the main difference being that AMB will never use just one speaker, and this results in smoother movement. The difference between the two systems becomes smaller, and the advantage moves towards AMB. -- FA Vor uns liegt ein weites Tal, die Sonne scheint - ein Glitzerstrahl. _______________________________________________ Sursound mailing list Sursound@music.vt.edu https://mail.music.vt.edu/mailman/listinfo/sursound
