Audio editing is used in TV, music, and film production to create and edit the perfect soundtrack. A sound editor or engineer builds the soundtrack by cutting the picture to synchronize it with sound elements. Their duties involve working with dialogue tracks, recordings, and analog and digital foley. Re-recording mixer responsibilities focus on the final sound balance, paying attention to volume levels as well as sound quality. Audio editing supervisors handle the sound post-production. They collaborate with the director to ensure the production soundtrack meets the requirements, stays within the budget, and everything proceeds as scheduled.
