Western Electric

In addition to being a supplier for AT&T, Western Electric also played a major role in the development and production of professional sound recording and reproducing equipment, including:

  • the Vitaphone system which brought sound to the movies;
  • the electrical recording technology adopted by record companies in the late 1920s (despite the popular electrical system used by Autograph Records and its manager, Orlando R. Marsh);
  • the Orthophonic phonograph, an acoustical phonograph with a flat frequency response tailored for reproduction of electrically recorded disks;
  • the Westrex optical sound that succeeded it;
  • the Westrex cutter and system for recording stereophonic sound in a single-groove gramophone record that was compatible with monophonic equipment.
