cinema sound history

The earliest feature-length movies with recorded sound included only music and effects. The first feature film originally presented as a talkie was The Jazz Singer, released in October 1927. A major hit, it was made with Vitaphone, which was at the time the leading brand of sound-on-disc technology.

Dolby cinema sound History

Dolby Stereo’s and the 1st sound system in cinema was the cp50 . The breakthrough came with the film release of “Star Wars” in 1977. Everyone sat up and took notice. Even though the 35mm optical sound quality was improved, the absolute creme-de-la-creme of movie sound was only obtainable from magnetic sound available only from 70mm prints. Therefore, the 70mm format was reintroduced to cinemagoers, still with 6-track stereo, but now Dolby encoded.

In 1965, American engineer and physicist Ray Dolby established Dolby Laboratories in London. His aim was to develop practical noise reduction systems for improving sound quality in a variety of professional and consumer environments. The resulting innovations have made Dolby a watchword for quality audio throughout the world
