ADR (Automated Dialogue Replacement)

Automated Dialogue Replacement (ADR), also called looping, is the process of re-recording an actor's dialogue in a controlled studio environment after filming, to replace production audio that was unusable or to change a line. The new dialogue is matched to the on-screen lip movements. Clean dialogue separation supports ADR workflows by isolating the original spoken track for reference, preserving the clean music & effects bed to layer the re-recorded dialogue on top of, and reducing how much needs to be re-recorded in the first place.
