When the Star Wars audio mix was revised for home video starting in 85, they brought some of the mono mix effects into the stereo/surround tracks. I’m not sure when they incorporated the targeting computer noises, but it was in one of those later revisions.
Would this stereo mix have been attached to the 1980 A New Hope release, or did it not appear until home video?
It’s another reason I’d love to have A New Hope Depecialized.
As he mentioned the remix was done in ‘85.
