What can I say? Sorry. But now the kids are back at school so I’ll try to be a bit more regular here.
For those interested in the evolution of audio systems used in cinemas, have a look at Nick’s Auditorium, a Belgian site in English, which has some fine explanations of the various audio standards, including a few that have bit the dust along the way. It also suggests that Star Wars was indeed not the first Dolby Stereo movie. It claims this for Lisztomania (albeit without any use of the surround channel), and in full-blown surround the site claims A Star is Born (the Streisand, not the Garland, version of course).
