What is ADR and when is it typically used?

• A. Analog Data Recording; used to capture sound from vintage mics.
• B. Active Dialogue Review; used during shooting.
• C. Automated Dialogue Replacement; used to replace or clean up dialogue in post.
• D. Automated Dynamic Rendering; used to generate visuals.

Answer: (C)

Automated Dialogue Replacement is a post-production technique used to replace or clean up dialogue after filming. When on-set audio is marred by noise, boom shadows, or equipment hum, or when a line needs to be changed, actors re-record their dialogue in a studio. The new performance is timed to match the on-screen lips and actions, typically using a clap or other cue to sync the new recordings with the footage. Once recorded, these ADR takes are polished and blended with effects and music to create a clear, cohesive final dialogue track. This is distinct from the original on-set recording and from Foley work, and it’s a common tool for ensuring dialogue is intelligible and natural-sounding.
