Dolby Stereo is a sound format made by Dolby Laboratories. It is a unified brand for two completely different basic systems: the Dolby SVA (stereo variable-area) 1976 system used with optical sound tracks on 35mm film,[1] and Dolby Stereo 70mm noise reduction on 6-channel magnetic soundtracks on 70mm prints.[2]
Dolby SVA significantly improves the development of sound effects in films and theorization of sound design by Walter Murch.[1] In 1982, it was adapted for home use as Dolby Surround when hi-fi capable consumer VCRs were introduced, and further improved in 1987 with the Dolby Pro Logic home decoding system.
