![]() ![]() Magnetic tracks were first used by filmmakers in the late 1940s for recording music. Magnetic recording offers better fidelity than optical sound, can be copied with less quality loss, and can be played back immediately without development. Today the principal use of optical recording is to make a master optical negative for final exhibition prints after all editing and rerecording have been completed. Sound waves were converted into light and recorded onto 35-mm film stock. Until the early 1950s the normal recording medium was film. Most of the improvements fall into three areas: fidelity of recording separation and then resynchronization of sound to picture and ability to manipulate sound during the postproduction stage. The art of sound recording for motion pictures has developed dramatically.
