Fun facts
  • The aspect ratio of this format shifted from 1:33:1 to 1.375:1 to accommodate space for a soundtrack
  • This process can include either an analog or digital soundtrack, and the signal can be recorded optically or magnetically
  • Prior to sound on film, the film's soundtrack could be played on a separate phonograph record or performed live
