Looking for a methodology to measure the acoustic response
of new video production studio. I'm not interested in software
modeling whatsoever. There is a 80' drape which covers most
of three walls except when using the green screen. I've notices
significant slap echo when shooting in this mode.
My thinking at this point is to place one speaker in three test
locations across the practical width of the room about 1/3 of
the way out from the backdrop wall. When we measure a
speakers frequency response the measurement microphone is
usually placed 3' from the speaker face. Placement of the
recording microphone in the room seems critical to
interpreting the frequency sweep data... the source of my
question. How do you accurately record a room's true sonic
signature?
There is no practical way of doing what you are asking.
Furthermore, if you DID have a "true sonic signature",
how do you think that would benefit you?
