I saw a recent production using Hollywood actors and a TV-oriented crew trying to do radio and getting entirely confused about how to handle the POV of somebody behind a door. It stopped them cold. I could see right through it, but they were stumped. If a character is up a tree or across a foggy moor, have the actors step back a few feet from the mic. Panning-wise, I tend to keep voices close to the center of the stereo spectrum and skip most translations of film movement.
Humans hear binaurally.
Panning is totally unnatural. I never mix with headphones in mind. Similarly, heavy handed exploitation of the 5.1 surround format will only call attention to itself and divert your listeners from the story. Re-creating Radio workshops . All rights reserved.
