Film Crew Slang

Room Tone- The "sound or noise" of a room, location or set where dialog is recorded during production. When the Assistant Director calls for Room Tone everyone settles down quietly, no speaking or movement until the Sound Crew calls cut after about 30 seconds of recording. Editors use it as as a "bed" to form continuous tone through a particular scene. Room Tone is sometimes confused with ambience, which might be sound effects or reverberation added when mixing dialogue.
