ADR

(Redirected From Automated Dialog Replacement)

ADR is an acronym that stands for “automated (or additional) dialog replacement,” and refers to the re-recording of dialogue after the filming of picture. ADR is also known as "looping."

In conventional film production, dialog is recorded while filming. Unfortunately, traffic, stage, or other noises often renders the production sound unusable. In films with computer-generated imagery, some of the "actors" are not actually present during the initial recording sessions and their voices must be added later. ADR is sometimes used to change the original dialogue lines or to remove profanity for a television broadcast or airline version. The original actor may or may not be called upon to record the ADR, so the replacement voice does not always match the original. ADR can also be used to re-dub singing or to localize the program for foreign release.

During an ADR session, the actor is called to a sound studio equipped with video playback and sound playback/recording equipment. The actor wears headphones and is shown the line of the film that must be replaced. The film is then played back several times, and the actor performs the line in sync with picture while an ADR Recordist records the performances. Several takes are made, and based on the quality and sync of the performances, one is selected and edited by an ADR Editor for use in the film.
