Dub (dubbing)

Dub (or dubbing) is the process of adding or replacing sound after the film has been shot. For example, recording sound in the post-production stage of production.

Most typically, the term refers to the substitution of the voices of the actors shown on the screen by those of different performers. They may be speaking a different language since many films are dubbed into the local language of a foreign market. Music is also usually dubbed into a film after editing is completed.
