Erm - excluding the use of prefade reverb it's actually one dimensional - moves left to right - prefade reverb allows you to move backward and forward - bringing it to 2 dimensional. > I'm thinking that UHJ format ambisonic encoding might prove more > useful.

Surround sound is two dimensional - it just uses the room reverb/delays instead of added ones. I.E. you hear the sound as being in front of you rather than to the side of you. Three dimensional would require height - which isn't really that useful. The problem is the listening environment - most people don't have surround for this - I do like the idea of widening the sound field - although it's already doable with phasing and stereo speakers. I don't think there's even a good stereo conference room. -- 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
