Missing technology, originally called "Infinitec", now branded as "Dolby3D". Unlike the others this is completely unrelated to sound, so this would definitely need a new section under technologies. Actually, I imagine it is worthy of its own page... (likely with a reference to Real_D, the competitor) 184.108.40.206 (talk) 07:25, 31 December 2007 (UTC)
Contradiction or Typo ?
"Dolby Digital Plus: audio codec based on Dolby Digital that is backward compatible"
Yet clicking on "Dolby Digital Plus" says "It is an incompatible development of the technologies used in the earlier Dolby Digital system.".
70mm Dolby Stereo
Dolby also improved the presentation of 70mm prints by applying (type A) and in later years (type SR).
Logan’s Run (1976) used five-screen front with mono surround with Dolby type A
Star Wars and Close Encounters the Third Kind (1977) was among two films to use subwoofer track that was dubbed as “Baby Boom”. It used two of the magnetic tracks on the 70mm and was played over the stage channels 2 and 4 that was commonly used for 5-screen fronts along with one mono surround channel.
Thou Star Wars used the inner two stage front channels, Close Encounters the Third Kind used sub bass arrays, presumable I assume they would be laid out beneath the stage channels.
(1978) saw the introduction of stereo surrounds that was dubbed split-surrounds on Superman The Movie and for the first time an even more realistic sound panning to create believable effects can be made to move around the audience.
So in sense Superman The Movie is the first film to use stereo surrounds, it was only Apocalypse Now (1979) that was publicized.
List of Dolby Stereo 70mm films at the In-70mm site, only a few dozen 70mm was ever turned out with stereo surrounds the rest was ether standard LCRS/subwoofer or five-screen/mono surround
Most projectionists would grumble over 35mm Dolby Stereo that was only a optical matrix format. It was 70mm that offered discrete sound as each part of the soundtrack has its own individual magnetic stripe on the print. — Preceding unsigned comment added by JBListening (talk • contribs) 18:28, 23 December 2010 (UTC)
