Okay, so far I'm about half done replacing the altered sound effects. I think the extra TIE fighter blasts during the quad laser battle will be the most difficult, because the whole scene has one continuous and prominent music cue. I try to keep the 35mm segments as brief as possible, because I want to retain as much dynamic range from the '93 version as I can, but necessarily any replacements will be somewhat compromised in that respect. I can partially compensate by selectively raising the volume, but it's always going to fall short of the original in that respect. The sound quality of the 35mm mix has noticeably lower fidelity, too, but that's the price that must be paid for the removal of inauthentic sounds. Thus far I think I've done pretty well disguising the inserts and making the transitions unnoticeable, so it shouldn't be much of a problem.

Satanika said he would take care of upmixing when it's done, so a 5.1 version will be available. I believe he used the ATSurround plugin for Foobar2000, which is probably pretty similar to Prologic II. I can't wait to hear this thing when it's completed. :)
