I agree with Jörn, doing this in analogue, today, for anything else than enacting a zen koan to enlighten apprentices, seems decidedly weird... but that's part of the point about art, right? If you really, really want to do analogue Ambisonic stuff, I suggest you look at the two (hand written!)

Thanks a lot for those papers. Beautiful. Same month year of my birth. Yes, I´ll do ambisonics and I´ll stay analogue as much as I can. There is a motive, but it is an artistic one. So, seems non sense to try to explain it here. You will just throw stones in my head just for that idea. Thanks

Thanks for your reply Jörn. You´ll have to excuse my basic english sentences, as it´s not my primary language. A-format panning as you call it has nothing to do with ambisonics per se, and the term frankly doesn't make much sense. the module you mention is a simple amplitude panner. so

A first-order B-format panner needs to implement the equations W = S * sqrt(1/2) X = S * cos(az) * cos(el) Y = S * sin(az) * cos(el) Z = S * sin(el) where S is the signal being panned and az and el define the direction. The Calrec Soundfield MkIV controller box has analog circuitry for

If you have any kind of calibration involved, rotating before running the A to B process makes that calibration meaningless. In fact, I'd say that one of the main reasons B-format exists is precisely that it makes processing like rotations a reasonable and general thing to do. David

Mathematically, _if_ you have a perfect A-format signal set (from some theoretical tetrahedral mic) then it can be panned. For the _simple_ case of a yaw of X degrees, then A' = ( A(1+cosX) + B(-sinX) + C(sinX) + D(1-cosX) ) /2 B' = ... etc. _I_think_ (this was very quick on the back of
