Hi Am I to understand that everything is OK if I use the third order plugins to work on my first order tetramic recording. And then I can expect everything to be as it should if I decode just the first order info via a first order ambdec ?
I do not at this time expect to add any second or third order signals in to my projects. As a follow up question, would it be to my advantage to have the input signals "converted" to third order and stay there even for the decoding Even if I only have a speaker rig of a circle of six horizontal and 2 speakers on the floor and 2 in the ceiling. Depending on the answer how about if I reconfigure the playback to a horizontal hexagonal ring of 6 and top and bottom rings of 4, the intra speaker distance in the 4 rings being the same as the distance between the speakers in the hexagon? Does third order decode add any advantage ?

When using a 3rd order max rE decoder with 1st order input, the gain on the first order signals is too high. The error is around 2.3 dB for a 2D decoder, and 3.5 dB for 3D. In both cases the resulting decode is closer to systematic (rV = 1) than to max rE. For an in-phase decoder the errors are higher, around 5 dB for 3D.
