But it is definitely the mono sound mix. Listen to the pre-Episode IV bootleg--it features the mono sound mix. The "Story of" LP is obviously much shorter than the actual movie, so it doesn't contain every scene, but it still features many of the differences. Compare the following scenes between the LP and the mono bootleg, or my mono mix web page. (Graciously hosted by our man Russs15)
-The alarm on the blockade runner
-Dice Ibegon's chirping sounds
-The sound effect when the Falcon comes out of hyperspace
-The sound of the Falcon caught in the tractor beam
-C-3PO's tractor beam line
-The comlink communication to Tarkin: "Governor Tarkin? We have an emergency alert in detention block AA-23."
-C-3PO's line: "What? Use the comlink? Oh my, I forgot, I turned it off."
-"Close the blast doors!"
-The countdown voice on the Death Star: "The rebel base will be in firing range in seven minutes." etc.
-During the Death Star battle, ship to ship transmissions aren't synthesized.
I believe these are all of the instances on the LP where a mono mix difference can be heard.
By the way, MoveAlong, I am still very much looking forward to your project. I saw the menus in the other thread and everything looks great.
