Re: [Sursound] Directional confusion between different B-format players

Well it could be something subtle ... then again it could be one of those classic coding errors ... ;-) Get Aaron Heller's "Eight Positions" off Ambisonia and massage that through your two bits of software ? If you can't get it, I have my own 26-positions (but you shouldn't need that for a L-<->-R swap problem ... though it will work just as well). I can send a copy. If you can eliminate a coding error ... then it gets interesting ...

My first thought is that the microphone used has its capsules more widely spaced than other tetrahedral mics, which could be leading to some directivity confusion at lower frequencies than usual, which in turn this material might be sensitive to. Certainly I've never noticed such an effect with VVmic, whether using a TetraMic or my previous native B-format arrangement.
