Hi Tim. I'm not an expert, and others on the list could much better answer your question. But as far as I know, irregular arrays like the new IMAX 12.0 are not well suited for ambisonics reproduction. There's at least one tool to create decoders for irregular arrays, depending on the exact positions of the speakers in the room, in relation to a sweet spot. But then you would need a custom decoder for each IMAX room... I'm thinking about The Ambisonic Decoder Toolkit: https://bitbucket.org/ambidecodertoolbox/adt.git. Maybe the author (Aaron Heller) would have more to say about it.
Another option is to use 12 virtual microphones (for example using SurroundZone2); that would be the easiest. Even if it would not be the most accurate method (in terms of ambisonics reproduction), it could be appropriate. -- Marc On Mon, 5 Sep 2016 14:25:20 -0700 "T Archer" <[email protected]> wrote: > Hi Marc, > > Thanks for getting back to me.
