History of Cinema Sound (to Home Cinema)
The history of home cinema starts in the 1920s when the first films with sound appeared. Up until the 1970s, most films had mono sound. Dolby Stereo appeared in the theaters in the 1970s. One of the most important films in Dolby Stereo was Star Wars. By applying Dolby noise reduction on a 70mm film the first sound track with 5.1 surround was born one of the first films was Apocalypse Now in 1978.
The quality standard THX (Tomlinson Holman Experience) was introduced in 1983 with the movie Star Wars: return of the Jedi. Dolby Digital was introduced in 1991 and one of the most important films was Batman returns. In 1993 a new standard came on the market with the arrival of Jurassic Park and DTS. The big difference with Dolby Digital was that the audio was recorded on a CD-ROM and thus the sound quality in the cinemas could be maintained because a film wears and thus the audio quality deteriorates. Also with the arrival of the movie Last action Hero the SDDS format of Sony appeared with 8 separate channels.
Only in 2010 did we go from 5.1 to discrete 7.1 in the cinema’s with the movie Toy Story 3. In 2012 we went from channel separated audio formats to object based channels … Dolby Atmos.

Despite the fact that it was almost 100 years ago that the first films with sound were there, there have not been many changes in the field of sound. Because we are now moving from channel-separated solutions to object-based solutions, there are many new possibilities to create a very realistic surround soundtracks.
