I used a Sony ECM-MS957 mid/side microphone on a chorus/organ in a conventional open space church with pillars and high ceilings, and the realism was stunning.
It’s been a long time since I read an article on spaced microphones for recording sound in a large space, orchestra or church, and I think the author claimed that certain distances work well between mics, based on what you were mentioning, Ken, namely the acoustic wavelength. It seems to me that in a church you’d want almost all “adjustments” to favor the very narrow bandwidth of the human voice, centered around 2.5kHz, whereas for serious music the very low frequencies enter the picture.
Close-up micing of the voice overcomes a lot of obstacles… it’s only when the mics are pulled a few feet back from the voice that phasing starts to smear the sound.
P.S. Using the “EDIT” feature I have returned with an additional thought. It is good to keep in mind that a single spoken human voice is a monaural instrument, not stereo. I had an interesting situation with a client who demanded to have a “surround sound” coming from one voice speaking from a lectern, and when I tried to explain that the monaural clarity of the voice at all listening points was the ideal goal, she puffed up her hubris and found me “argumentative.” I don’t know if she ever got her “surround sound” coming from a single voice. Maybe she is thinking of the Voice of God in a Charlton Heston Movie.
Thanks for letting me chime in and share your interesting project.
