A recording of the ambient noise of a shooting location used to fill in gaps in the dialogue?

• A. Background Noise
• B. Room Tone
• C. Ambient Bed
• D. Wild Track

Answer: (B)

Room tone is the neutral, quiet ambient sound of a location recorded during a moment when there’s no dialogue. The idea behind it is to give editors a seamless audio “filler” that matches the room’s natural noise floor, so when dialogue is cut, moved, or gaps appear, the sound doesn’t suddenly jump or drift. By dropping in a brief room-tone recording with the same microphone setup and level as the scene, editors can crossfade and extend pauses smoothly, keeping the scene sounding real and continuous.

This isn’t just any background noise or a musical texture. Background noise is a broad term for all ambient sounds; an ambient bed implies musical or atmospheric underlay; a wild track is a separate, often unsynced recording of sounds used for sound design. Room tone serves the precise purpose of preserving consistent ambience to hide edits in dialogue.
