Playback singing is a technique used in the film industry where a singer records songs that are later synchronized with the actors' lip movements on screen. This allows for a polished audio experience, as professional singers can deliver high-quality performances that enhance the film's emotional impact. In many countries, especially in India, playback singing is a vital part of the movie-making process. Famous playback singers, such as Lata Mangeshkar and Kishore Kumar, have become iconic figures, contributing significantly to the popularity of film music. This practice allows actors to focus on their performances while leaving the singing to skilled vocalists.
