Thanks to lusho720, we have a new source for the Han-Greedo scene. It’s also an old VHS capture with some muffling, but the quality is good, considering. In its current state, it’s not much different than what we have now, but I think it may respond better to attempts to un-muffle the audio, because it hasn’t already been processed like the other track. We’ll see.
If anyone has any experience un-muffling old VHS tapes, let me know. I’m brand new to this.
EDIT: I think this will result in a marginal improvement. I was able to do a spectrum analysis on the 35mm audio and equivalent section of VHS audio, generate a custom EQ to match, and it comes out still pretty muffled but without the boomy bass of the original VHS section (the 35mm track is a little treble-heavy due to lack of Dolby NR, and that hasn’t changed). So compared with the way it was before, the quality still drops but the EQ matches better. I think that’s a good thing. I’ll give it some more time for listening and correction attempts before I make the call to upload it or not.
