Dubbing (re-recording and mixing) is a post-production process used in filmmaking and video production, often in concert with sound design, in which additional or supplementary recordings (doubles) are lip-synced and “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, and 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.
