View source for Dolby Pro Logic II

===Background===
'''Dolby Pro Logic II''' 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.

'''Visuals:''' On a black background, clouds of fire burst onto the screen, revealing the Dolby logo in golden 3D. We can see "SURROUND" below, and "PRO LOGIC II" under it, written on a golden bar.

'''Variants:'''
* Sometimes on titles like ''Monster Jam: Maximum Destruction'' for GameCube, copyright info is shown at the bottom.
* On some later games like ''Genji: Dawn of the Samurai'' for the PS2, the logo has a sleeker appearance and "DIGITAL" replaces "SURROUND".
* There's a re-done version used on some other later games. A fiery explosion plays in reverse, then forwards again, revealing the Dolby Pro Logic II logo albeit in a plain white form (like the first logo). Occasionally this version simply reads "Dolby Digital".

'''Technique:''' CGI.

'''Audio:''' A burst of windy fire.

'''Availability:'''  Appears on some games from the time, like ''Star Wars: The Clone Wars'' (GameCube port only), ''Atelier Iris: Eternal Mana'', and ''I-Ninja''. This trailer is also available on the Dolby demo disc ''Explore Our World: We've Got the Whole World Listening''. The later version can be seen on the PS2 and Wii versions of ''Scarface: The World Is Yours'' (while the PC and Xbox versions have the "Digital" variant) and ''Metal Gear Solid 3: Subsistence''. Both the Pro Logic II and Digital variants can be seen on ''Terminator 3: Rise of the Machines'' on PS2, though these need to be enabled in the options before they play.
