- Abstract
- The quality of 35mm optical soundtracks using existing recording and playback techniques is examined. An analysis is made of the capability of the optical medium; it is shown that a flat recording and playback characteristic, together with the use of the Dolby noise reduction system, frees the track from many of the limitations imposed by traditional recording techniques. The new recording and reproduction method offers improved noise figures, better frequency response and lower distortion, yet the optical print is compatible in an unconverted theater. The practical implications of using the new technique throughout the recording chain are discussed.
