Dubbing, mixing or re-recording, is a post-production process used in filmmaking and video production in which additional or supplementary recordings 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, music – the dubbing mixers proceed to balance all of the elements and record the finished soundtrack.
