guess i'm not being clear, or just don't understand.
mics are designed to "point" in a particular direction, as i understand it, based on the capsel regaurdless of ld/sd. take a stereo mic for example(neumann sm69) if you were to run this horizontal, wouldn't you be picking up sound from the vertical plane? granted noone here is likely to use this, but, if you're not pointing the capsel towards the sound then you're recording what it's pointed at. ground, sky, the nitwit next to you........... i don't know, maybe i'm not right here but, if you want to shoot somebody you useualy point the gun at them, not in the air.
please correct me if i'm off base here.
