Amusing musings :-) If you want the rear sounds not to be swapped that means you want front/back symmetry. A pair of cardioids or hypercardioids pointing left and right (i.e. 90 and -90 degrees azimuth) will do that. I'm doing this routinely to provide stereo sound (for video recordings) of surround concerts, using two virtual hypercardioids derived from a Tetramic. Reducing the 180 degrees angle a bit provides some 'front dominance'. Regarding 'multiplexing', anything that can be done that way without actually moving the mics can be done as well in parallel... In this case, you can obtain a 'back' Blumlein pair with the correct orientation without moving the mics - just invert and swap the L and R signals. Then adding those to the original L and R you get two fig-8 mics pointing in opposite directions, so you just get two antiphase signals and a front and back zero. Ciao, -- FA A world of exhaustive, reliable metadata would be an utopia. It's also a pipe-dream, founded on self-delusion, nerd hubris and hysterically inflated market opportunities.
