Thanks everyone, not doing it saves a lot of faffing around! Oh and Paul, no problem with heaters, as we can turn them off. Only the performers, a cameraman, and I. We don’t have to keep punters warm! Cheers Steve > On 12 Sep 2018, at 15:21, Fons Adriaensen wrote: > > On Tue, Sep 11, 2018 a

Thanks David, that makes sense. If i kept the performers within the horizontal spread of 2 capsules, rather than pointing at them, would there be any benefit? Ie 2 capsules axis parallel to the horizontal plane. So in effect the performance will be contained within 60 degrees of the 90. Or maybe

Actually, directly on axis of one of the capsules may be the worst direction for a tetrahedral array. While it's true that otherwise you are slightly off-axis for a given capsule, with whatever coloration that might cause, I believe the non-coincidence problems of the complete array overwhelm this

Hi Folks Is it better to align performers to capsule axis, to get the best frequency, and noise performance from those directions, then rotate the b-format encode afterwards? I am recording at Union Chapel, with tetrahedral mics, and spot microphones. The final output will be stereo and HOA.
