I read this many years ago so cannot remember a source, but I think on-axis is not the best direction for a tetrahedral array. I think I was told this because I was trying to design an array with the capsules at 0, 90, 180 and 270 because it would be easier to do (before 3d printing arrived).

I am recording at Union Chapel, with tetrahedral mics, and spot microphones. The final output will be stereo and HOA. I usually just position tetra mics as normal (upside down and end-fire), but it occurred to me that it may be better to align the capsules to performers (where possible). All performers will be spread out horizontally on an equilateral triangle, with the main tetra on a corner. The main decode will be stereo, but I want to capture the acoustic of the place, and do a HOA mix.
