Folks- All of us get this request from time to time- from the audience members or from naive music directors. I never know quite how to explain why this is a problem- why it seldom works. I assume that scientific papers have been written to explain the differences in how an audience member listening (and looking) at an orchestra will perceive the music very differently than a microphone placed in the same spot. Neumann dummy heads ( Georg Neumann GmbH - Products/Hist. Microphones/KU 81/Publications) do not, to my ears, change this. Assuming you agree with me, does anyone have a simple explanation why we don't simply place microphones at, say, the fourth row center at Carnegie Hall and call it good?
