The original 1977, 1980, and 1983 sound mixes are all at significantly lower levels than the Hairy Hen 5.1 Purist mix on my copies of the DE ED editions.

Well, I haven't verified this, but I would not be surprised at all. All of our audio resources were made by different people from different sources, and different levels is a sign of that.

Also, different mixes have different dynamics, so there is simply no way to make the levels match exactly all the way through. If you match peak levels, then the '85 mix will be louder than the '93 mix because the '85 mix has no dynamic range. Matching "normal dialogue" levels doesn't really work with Star Wars because the movies are so driven by the score, and it ends up matching even worse. So no matter how you try to make them match, they won't match exactly. Not to mention the fact that DTS is louder than AC3. And let's not even get into the dubs.

That said, I'm sure they could be better-matched than they are right now, and I apologize for my contribution to the problem. The 85 mix was normalized 3dB louder than hairy_hen's mixes, and I didn't think it was my place to make changes to someone else's work, so the DTS track I gave Harmy is exactly as I found it. For my own personal collection, I reduced the volume by 3dB so at least the peaks match (if nothing else). Then when Harmy wanted a lossy option, I was lazy and gave him my -3dB modified version. But it's in AC3 format which means it still won't match peak levels with hairy_hen's lossless track...
