I’m having a curious issue with an MS decoding. I did a standard mic setup with cardioid and figure-8, then copied the the f-8 audio file onto an additional track and reversed the polarity on it, panned the sides tracks hard L&R and the mid track centered. But when the mixing bus sums these signals, the right channel level ends up about 2dB hotter than the left. (The reverse polarity side track is panned to the right.) Here’s the interesting part: if I “mirror reverse” eq the side tracks, boosting on one side and cutting on the other, exactly, the mix bus channel levels start to even out–with more extreme cut/boost levels producing more evening out. This suggests to me that the mid track summing with the left, non-polarity reversed side channel is producing some phase cancellation at the mix bus stage. Is there something I’m missing in the M/S decoding process?
