Dubbing of motion pictures

Dubbing (also known as re-recording and mixing) is a post-production process used in filmmaking and video production where supplementary recordings (known as doubles) are lip-synced and "mixed" with original production audio to create the final product. Often this process is performed on films by replacing the original language to offer voiced-over translations. After sound editors edit and prepare all the necessary tracks—dialogue, automated dialogue replacement (ADR), effects, Foley, and music—the dubbing mixers proceed to balance all of the elements and record the finished soundtrack. While dubbing and ADR are similar processes that focus on enhancing and replacing dialogue audio, ADR is a process in which the original actors re-record and synchronize audio segments. This allows filmmakers to replace unclear dialogue if there are issues with the script, background noise, or the original recording. The term "dubbing" commonly refers to the replacement of actors' voices with those of different performers who recite their dialogue for international audiences, typically in a different language from the original dialogue. When a voice is created from scratch for animations, the term "original voice" is used, since these media are often partially finished before the voice is implemented. The voice work would still be part of the creation process, thus being considered the official voice.
