There aren't yet, but I'm actually starting work on a new version of ESB right now.

As with SW, the main benefit will be the improved surround decoding. Further changes from the previous version will be minimal. I think I'll have another shot at integrating the missing snowspeeder crash sound into the '93 mix to see if I can get it to work more seamlessly. As yet I'm undecided as to whether the original stereo mix or the '97 SE would be a better source for this (it sounds somewhat different in each).

I'm thinking of reworking the LFE channel somewhat, but I'm not sure how extensively I'd want to change things around, since it already sounds rather good in the previous version. Unfortunately, the in-theater 70mm recording of ESB is too low quality for me to make out the low end of the mix with much clarity—even when boosting the bass by 18 dB I can still only just barely hear it. With a hifi subwoofer or headphones I can pick out enough nuances in bass tones that I think I know what the original is supposed to sound like; or at least, I have a very rough idea of what bass was there and what wasn't. It actually sounds like it's pretty similar to what's already in the '93 mix, which isn't really all that surprising. But even if the content is starting to come into focus a little more, the levels remain a complete mystery, and anything I do is still only a guess at how they might have done it back then. So in the end I just have to go with what sounds good, as before.
