The ADR editor oversees the procedure and takes the corrupted dialogue, and replaces it with newly recorded lines to the actor's mouth on film to make it lip sync correctly.

The ADR editor or dialogue editor also work with the walla group in films which they are required, providing the background chatter noise in scenes with large crowds, such as parties or restaurants.
