Is the current state of affairs regarding the mono audio track still that we have a version recovered from a recording using a cassette player? It’s not like someone has gotten the mono mix from a print or anything, right?
It’s actually mainly sourced from a European arial VHS recording.
There have been 16mm prints with mono mixes but they sound worse than the one from DeSpecialized and 4k77. Puggo’s version of ANH contains this mono mix and you can hear lots of hissing and warbling. I don’t know if thre have been any other discoveries since then…
