Would I be correct in saying that the ideal control room environment would be one in which the sound is effectively projected through the mix position and then absorbed so that only the origional signal is heard by the engineer? In this case would any treatment really be required at the front of the room other than angling walls and ceiling to avoid reflections into the mix position? If this is so why do you see so many control rooms with overhead diffusers? Why not just absord everything past the mix position? If I have this concept all up the putt can someone please set me straight . Thanks again.
