Till the last century concluded, the sound was dubbed after the completion of the film. The stars were to dub the dialogues. The background scores were retrofitted and mixed later. All this was the job of the sound designer. In the new millennium, Lagan was first to use the sync sound. It recorded dialogues, and sounds while shooting live. In other words, the film is shot indoors in a sound proof studio and outdoors by eliminating the external sound. Farhan’s DCH followed in sync. Gowarikar who directed Lagaan used sync in Swades and Jodha Akbar.The sound designer manages dubbing when the actors have to recreate the dialogues after a time lag. The sound designer is available on the sets and outdoors when the film is shot in sync. Non-human sounds are shot by foley. Thus the final sound-track is a mix of dubbing tracks, background music and foley. The volumes of different sounds are managed at the appropriate levels. In sync films, there is additional process of sound cleaning — removing all unnecessary sounds and refining the desired ones. The whole sound designing takes 3-6 months by a team of 6-8 people headed by the sound designer. In practice, the film’s copy comes to them barely two months before the releas. They are short of time.
