The Mixpre recorders had a similar issue with MS encoding when they first came out - it took a few revisions before that got sorted out. So it wouldn't surprise me that something similar is happening here. Cordially, Rudy ChalupaPleiades Audio + Electronics

The level difference is 16 dB. This is a first order ambisonic recording (with a Core Sound Tetramic). Someone from Sound Devices assumed that this level difference may be due to the conversion. Now I know normalizations are used for the conversion from A to B-format (SN3D, maxN), but I can't work out the mathematics behind it. Anyway, looking at it does in no way seem to explain a level difference of 16 dB. Now I was wondering: is there any level difference to be expected between A-format and B-format Ambix or FuMa? How much? I do not like to make wrong statements to someone who should be helping me fixing a bug. So, could someone enlighten me on this subject?
