[Jukebox-list] Movie Sound

[Ron Rich]

Ed, 
  Wasn't "Vitaphone" a news reel type short--or am I getting it mixed up with "Movie Tone"--or did Movie Tone use Vitaphone?
  What are "variable density soundracks"--the sound on film process??

  I believe playing records in sync to produce a film's soundtrack was called the "Vitaphone" system and was largely phased out by the 30s when variable density soundtracks became common.

He had this one locked in a special "fire proof" safe, in a side room, ajoining the projection room. I think he told me that there was some type of "law", or company regulation, that required that no more then three rolls of the film could be in the projection room at any time. Ron Rich
