Stefan: These guys won't have anything for the public for another YEAR+ . . . so any thought of a substantial announcement at CES 2011 was based on "misinformation." This is a standards group that is still figuring out who is going to PAY to PLAY. Which brings us back to the key question -- WHO is going to PAY to get Dr. Farina (or a suitable substitute) involved? Mark Stahlman Brooklyn NY In a message dated 1/10/2011 12:55:10 P.M.

Hi... Some further link related to 3D Audio Alliance: http://www.ultimateavmag.com/content/srs-advanced-rendering-lab However, there doesn't have to be a lot of activity at CES 2011.

So much to the best "open" intents. ("Open-source" and "open" doesn't have to be the same in this area, small hint...) Best, Stefan P.S.: In fact, they didn't demonstrate any 3D source. (Even if they could have done, see configuration.)
