It automatically senses what order it's being fed and configures itself accordingly. You might contact Daniel Rudrich at IEM to ask about details. https://plugins.iem.at/docs/plugindescriptions/#binauraldecoder Len Moskowitz (mosko...@core-sound.com) Core Sound LLC www.core-sound.com Home of OctoMic and TetraMic -- next part -- An HTML attachment was scrubbed...

Re: [Sursound] Accompanying video display
As a film sound designer and fan of spatial sound, I think it’s very important for cinema sound to be mixed and reviewed in the same type of environment as a movie theatre, in other words with a projection screen and the front speakers behind the "acoustically transparent" screen. Working with a hard screen like a big TV means placing the front speakers outside the screen, which leads to difficulties in correctly panning across the front speakers. For cost reasons many edit and design rooms are equipped with flat panel displays of various types. That easily delivers the best picture quality for the money. If that is what you do I’d place the LCR monitors below or above the screen with the L and R speakers’ high frequency drivers placed within the screen area. Best of luck!

[Sursound] Accompanying video display
Hello friends- I’m helping to design a new studio on the campus where I work. We are installing a 7.1.4 setup which is very exciting. I’m looking for assistance on what type and size video to install. The room is 14’ tall, 11.5’ wide, and 19.5’ deep. What type of video would you suggest (screen vs projector) and how large? We plan to use this space for vpostproduction work for video and gaming as well as a teaching studio for immersive audio so having a large, legible screen is very important.

Re: [Sursound] Decoding first order ambisonics on higher order decoders?
Which decoder configuration for FOA and TOA in to binaural is the best? Any references?
