Yeah, awesome till you get a stereo->mono mix and then phase inconsistencies make it mute itself (i.e. left phase inverted from right then summed). > The surround image is likely only going to be optimal in one "sweet > spot" in the listening room.

Yeah, although they would hear some effect if the speakers were far enough away. > The question is, will anyone benefit at all?

I just don't know anyone with hardware capable of reproducing it. Don't get me wrong, I think it would be awesome, but it needs to be supported at each endpoint (or as you stated - fall back to a working methodology). > There's also a question of scale.

Heh, if you're paying $750k for a room, you should definitely have this - as well as a full hd telepresence suite. It would definitely allow multiple speakers to be more easily distinguished from each other while talking at the same time. -- Kind Regards, Matt Riddell Director _______________________________________________ http://www.venturevoip.com (Great new VoIP end to end solution) http://www.venturevoip.com/news.php (Daily Asterisk News - html) http://www.venturevoip.com/newrssfeed.php (Daily Asterisk News - rss) _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
