I imagine you are still interested in details about the ’85. Nothing documented to pass along, sorry. To be honest, I’m not as familiar with the ’85 as the others. When I did a transfer of the original Dolby Stereo from the CAV P&S Laserdiscs, I used bits of it to patch and fill in a few spots. Aside from the modifications in content, it seems very similar the Dolby Stereo - same overall EQ, same restrictions in dynamics and low end. Based on this, and what I now know from the Ioan Allen article (thanks for that!) my guess is that they used the “limited” LT/RT master as the original source. What is interesting is that the stereo image (at least in the few areas I worked with) is wider - particularly the music, which is why I always thought it was remixed from stems. This now seems highly unlikely based on the information in the Ioan Allen article. It’s certainly possible the wider image was achieved through processing, but it does bear further investigation. Any details you know of, please pass them along!
I’m just finishing up the 70mm “in Theater” vs. ‘93 mix comparison mentioned earlier in this thread, which I will try to make available here. Then I’m back to completing the restoration of Moth3r’s mono mix. Perhaps after that I will take a closer listen to the ’85.
