Automatic Dialog Replacement

The process of re-recording dialog in the studio in synchronization with the picture.
Dubbing studio

Dubbing, mixing, or re-recording is a post-production process used in filmmaking and video production in which additional or supplementary recordings are "mixed" with original production sound to create the finished soundtrack.

The process usually takes place on a dub stage. After sound editors edit and prepare all the necessary tracks – dialogue, automated dialogue replacement (ADR), effects, Foley, music – the dubbing mixers proceed to balance all of the elements and record the finished soundtrack. Dubbing is sometimes confused with ADR, also known as "additional dialogue replacement", "automated dialogue recording" and "looping", in which the original actors re-record and synchronize audio segments.

Outside the film industry, the term "dubbing" commonly refers to the replacement of the actor's voices with those of different performers speaking another language, which is called "revoicing" in the film industry.

Automated Dialog Replacement (ADR) is the process of re-recording dialogue by the original actor after the filming process to improve audio quality or reflect dialogue changes (also known as "looping" or a "looping session"). In India the process is simply known as "dubbing", while in the UK, it is also called "post-synchronisation" or "post-sync". The insertion of voice actor performances for animation, such as computer generated imagery or animated cartoons, is often referred to as ADR although it generally does not replace existing dialogue.

The ADR process may be used to:

  • remove extraneous sounds such as production equipment noise, traffic, wind, or other undesirable sounds from the environment;
  • change the original lines recorded on set to clarify context;
  • improve diction or correct an accent;
  • improve comedic timing or dramatic timing;
  • correct technical issues with synchronization;
  • use a studio-quality singing performance or provide a voice-double for actors who are poor vocalists;
  • add or remove content for legal purposes (such as removing an unauthorized trademarked name);
  • add or remove a product placement;
  • correct a misspoken line not caught during filming.
  • replace foul language for TV broadcasts of the movie.

In conventional film production, a production sound mixer records dialogue during filming. During post-production, a supervising sound editor, or ADR supervisor, reviews all of the dialogue in the film and decides which lines must be re-recorded. ADR is recorded during an ADR session, which takes place in a specialized sound studio. The actor, usually the original actor from the set, views the scene with the original sound, then attempts to recreate the performance. Over the course of multiple takes, the actor performs the lines while watching the scene; the most suitable take becomes the final version. The ADR process does not always take place in a post-production studio. The process may be recorded on location, with mobile equipment. ADR can also be recorded without showing the actor the image they must match, but by having them listen to the performance, since some actors believe that watching themselves act can degrade subsequent performances.
