Then the Definitive Collection came out, from a fresh interpositive of each movie, but a much revised sound track for ANH (everything that was included was from the mono mix).
Not entirely true. Yes there were elements from the mono mix restored to the 1993 mix but there were additional changes made that weren’t present in any previous mix. Additional glass breaking during the detention block shoot out comes to mind, additional laser like fly by sounds for the Alderaan remnants when the Falcon comes out of hyperspace I’m fairly sure was new. So really the 1993 mix is a hybrid of things new and old.
