Dolby Pro Logic II

Background: Dolby Pro Logic is a sound processing system developed by Dolby Labs to decode film and TV soundtracks encoded in Dolby Surround, which allows a stereo soundtrack encoded with it to be transformed into 4.0 surround (left, center, right, and center surround). The second version of this system was introduced in 2000, transforming a standard stereo or Dolby Surround-encoded soundtrack into full 5.1 surround. The system was since expanded to add in a center surround channel and height channels.
