Which measurement tool shows the phase relationship between left and right channels in a stereo mix?
Answer: Vectorscope (correlation meter)
A vectorscope or correlation meter displays the phase relationship between stereo channels. A reading near +1 indicates good mono compatibility, while negative correlation can cause phase cancellation issues.
What is 'dialogue editing' in film post-production primarily concerned with?
Answer: Cleaning, syncing, and cutting recorded speech for clarity
Dialogue editing involves synchronizing production audio to picture, removing unwanted sounds, smoothing edits, and preparing clean dialogue tracks for the final mix and ADR sessions.
What is the function of a 'room tone' in post-production?
Answer: The ambient silence of a location, used to fill gaps in dialogue editing
Room tone is recorded silence of the production location. It captures the unique ambient noise of a space and is used during editing to fill cuts in dialogue so that silence doesn't feel abrupt or unnatural.
In post-production, what does LUFS measure?
Answer: Loudness Units relative to Full Scale — a perceptual loudness measurement
LUFS (Loudness Units relative to Full Scale) is a standardized measurement of perceived loudness used in broadcast and streaming delivery. Platforms like Netflix (-27 LKFS) and Spotify (-14 LUFS) specify target integrated loudness levels.
What is the role of an 'M&E track' (Music & Effects) in post-production delivery?
Answer: A stem mix without dialogue, used for international dubbing
The M&E (Music & Effects) track is a mix that contains all audio except dialogue. It is used for international distribution so foreign language dubbing can be added over the existing music and effects bed.
In a post-production mixing session, which technique addresses low-frequency buildup in a room recording without removing presence?
Answer: Using a dynamic EQ to cut resonant frequencies only when they exceed a threshold
A dynamic EQ applies frequency-specific gain reduction only when the signal at that frequency exceeds a set threshold. This is preferred over static high-pass filtering when you want to retain warmth but control intermittent resonance.
