This recording is of interest as it is one of the two known sources of the original theatrical mono mix (details). Although parts of my tape are extremely worn, and several sections of audio are missing, the quality is generally better than the audio from the '77 bootleg tapes (which suffer from generational losses). (The EditDroid DVD, recently posted on the newsgroup, featured the mono mix taken from one of these bootleg tapes.)
I originally made the audio available in two formats, MP3 (50MB) and lossless FLAC (320MB). See this thread. Molly attempted to use the mono audio with the EditDroid video in her Prototype "XP77:4EB" Edit, however she wasn't totally sucessful in achieving good sync. Since then, AFAIK no-one else has done anything with this audio.
So I decided, just for fun, to see if I could create an alernative audio track for my DVD. I re-recorded the audio from the VHS, and this time I captured the video as well to use as a reference aid for sync. The process wasn't as easy as I first thought, as quite often scenes on the tape run 2-4 frames longer than those off the laserdisc. Eventually however, I ended up with an audio file, padded and trimmed where necessary, that syncs up near perfectly with the video from my ANH DVD. I've not made any attempt to fill in the blank bits, or to adjust the pitch to account for the PAL "helium" effect, but I decided to release what I've done for those die-hard SW geeks among us!
To be uploaded to the newsgroup in the next day or so is an 80MB Dolby Digital .ac3 file in 1.0 mono, which has the exact same length as the video on my DVD.
If you have a copy of the DVD, it's a simple job to extract the video (e.g. use DVDDecrypter in IFO mode) and re-author with this new audio (e.g. use DVDAuthorGUI). You could extract the 2.0 Dolby Surround mix off the DVD as well, and put both mixes on a new DVD, but then the output would be marginally too big for a single layer DVDR. (You could always transcode the video with DVDShrink).
