Just putting this out there, I'm rebuilding the 1977 Zoetrope® 6 Channel audio, in effect its 5.1 surround. I'm using the 1977 Mono muxed to support all 6 channels and normalized to the 5.1 levels to build each track.

I saw the pre messed with version 57 times, I was a sonar tech and know my sound....

You mean you have the original 1977 surround audio? From the 70mm?

And what do you mean by using the 1977 mono? The 1977 mono mix has differences compared to the 6-channel I think?

This is very interesting and it would be nice to know more details if you'd share them, or create a thread about it!
