I've checked over the file from Satanika and everything sounds just the way it should, so I'm pleased to announce that my rendition of Empire in 5.1 is now available for general use. To my ear this is the best-sounding audio version of the film out there--it has a very good balance without anything standing out as flashy or out of place, with strong dynamics and powerful bass when appropriate. Its overall quality is most likely very similar to what the 70mm mix would have sounded like, though it does not claim to represent that version in its specific details. The AC3 file is split into a two part rar archive.

Anyone wishing to use my audio for their own projects is welcome to do so, provided the video is properly synched to the NTSC version of the GOUT. I'd be very interested in hearing feedback and impressions of this mix from anyone who obtains it.
