Welcome to a very special thread on AVS Forum, presented by Sony, which provides you the opportunity to ask any questions you like about immersive audio. In this relatively new approach to audio reproduction, sounds come from above as well as around the listener, a concept epitomized by Dolby Atmos, DTS:X, and Auro 3D. It's taking place right now and runs from 11:00 AM to 12:30 PM Pacific time (2:00 PM to 3:30 PM Eastern time). Tech expert Bob O'Donnell will monitor the thread during that hour and a half for your questions on this hot topic and post his answers on the spot.

To get this party started, we began a pre-event thread inviting AVS members to post questions ahead of time, and many of you responded with some great ones. Bob will begin by answering a few of those up front. Meanwhile, feel free to post your questions in the new thread—the one you're reading now—and Bob will respond to as many as he can.

Because of the functionality of AVS Forum, we decided the best way to conduct the AMA is within a standard thread. This allows people to quote and search for specific posts, but it also means you'll need to reload the page often to see Bob's responses as well any new questions that are posted. Also, because of time constraints, he probably won't be able to answer every question.

In addition to getting answers about immersive audio, those who submit a question will be automatically entered to win a Sony STR-DN1080 AV receiver with support for Dolby Atmos and DTS:X as well as many other advanced features. The winner will be selected by random drawing from among those who submit at least one question; submitting more than one question will not increase your chance of winning. The drawing and announcement of the winner will be made at the end of the live session around 12:30 PM Pacific/3:30 PM Eastern.

After the live session has ended, this thread will remain open for 48 hours, during which Bob will answer as many remaining relevant questions as he can. However, he won't respond to questions posted after the live session is over. After 48 hours, the thread will be closed.

If you're confused about immersive audio, you've come to the right place. What would you like to know about it? Post your question(s) here and follow the thread in real time for the answers.
