That would be great. Thanks :-)
I was thinking if it would be possible to have PCM (or some sort of HD audio) for all three original mixes. I will probably have DTS-HD for the 70mm 6 track but what about the other two? I'm really ignorant when it comes to audio (all you need to do to understand the depth of my unforgivable ignorance is read my answer to the last part of this post). Obviously upmixing (or whatever the audio equivalent of upscaling is) entire mixes to PCM from lossy encodes would likely be a waste of space (I guess it would be kind of like re-encoding a 2GB 720p mkv to lossless avi without any other changes and releasing it that way), so there'd either have to be some direct hi-fi (I'm not even sure if that's the right term in the context) sources of the mixes or they'd have to be reconstructed from other hi-fi/lossless sources.
I have no idea what kind of sources there are for the 77 stereo mix or what the possibilities would be on recreating it from some existing lossless elements - like how different is the '93 LD track from it.
However I contacted Puggo and he confirmed that he still has the wav files of his capture of the monomix track from 16mm film, which I suppose would be more PCM worthy than a VHS TV recording capture (though the audio qulity of Belbucus' mix is suprisingly good considering the source). It would be great if one of our audio geniuses could take Puggo's and Belbucus' lossless files and use Puggo's as the main body of the mix and do some sort of cleanup (I'm not quite sure what the exact possibilities are but most videos on film restoration I've seen also mention soundtrack cleanup, so it is possible I guess) and use Belbucus' to patch up the places where there were splices or dropouts in the 16mm track.
Like I said (many times) before, I don't know the first thing about audio editing and audio in general, so I have no idea how difficult this may be and how much of a difference it would make compared to what we already have, but it sure would be cool to be able to put all the original mixes in lossless audio on the BD.
