I noticed that though the telecine fold-downs have the echo effect (I don't think the two channels are folded down exactly in sync), but when I use "Audio Device -> Mono" in VLC to combine the two channels of the '77 stereo track on DJ's release, it's cancelled out. When I use "Cancel vocals" in GoldWave, the echo is left behind, and it sounds very odd. It's almost like they mixed in a low-volume mono fold-down of the music out of sync (creating a reverb/echo effect), with the two channels being inverse to one another (meaning that if the end result is folded down to mono in exact sync, the echo would be cancelled out). I tried that in GoldWave with the end credits from the OST, and the end result sounds similar to what's on the '77 stereo. Was it some sort of artificial reverb effect put in intentionally, or possibly some weird artifact from the fold-down from 4-track to 2-track? I think all the mixes have *some* added reverb in the music, but the '77 stereo is the only version to have this peculiar "wall of sound" echo. (I can kind of hear it in the music in other parts besides the two mentioned, but it's most pronounced in the Falcon battle and end credits. Skimming through it, I notice it during the opening crawl, the Falcon in the tractor beam, the Falcon takeoff from the Death Star, and the throne room music as well. Again, it's most noticeable if you listen to the brass in the music. And I was wrong, the '85 is wider - in fact, maybe this weird echo is part of what makes the music sound "narrower" in the '77.)
Speaking of echo, h_h, what's with the odd echo effect in the Death Star explosion, and is it going to be changed in the new version? I like the added LFE punch, but as I said, there's a strange echo almost like two sounds playing at the same time, slightly out of step with one another. (Was that due to combining elements from the '93 and SE explosion effects?)
