I made some GOUT-synced Laserdisc audio files... (Released)
Time

I've considered it, but I'll admit it's pretty low on my list.  My motivation for the ESB and ROTJ tracks were:

1) AFAICT, no GOUT-synced lossless original stereo tracks existed for these films.

2) Existing ROTJ tracks had a sync problem.

3) I needed to practice/learn syncing audio for an unrelated project.

Frankly I don't think my skill at audio sync and repair measures up to what Belbucus and others have demonstrated, so I steer clear of Star Wars simply because it looks like the pro interest is already there.  I'll probably be quite happy with the digital SW audio from the Japanese P&S disc, and it's hard to be motivated when you're not dissatisfied with the status quo.

Also I've recently learned that I hate working with audio, with a passion ;)

Monty Python and the Holy Grail -- 1975 theatrical (on hiatus - lots of info)
Time

This is interesting...

The PITCH of the commentary on the Blu-ray is 4% lower than the pitch on the Laserdisc, which I take to mean that the Laserdisc commentary was originally PAL.  But the quiet soundtrack underneath the two commentaries is the same pitch, meaning it was mixed in later.

So, what to do?  I believe the Blu-ray pitch is probably correct.  I may try to just pitch-correct the bits of dialogue that are missing from the Blu Ray (from around the video edit) and merge them into the Blu-ray commentary.  It's just a commentary track so I can live with that.  Other suggestions welcome.

EDIT: Nevermind, the Criterion commentary covers the Anthrax extension so I'd have to edit it anyway.  So basically unless I hear otherwise I'm merging the Blu Ray two-channel mono track back down to proper single-channel mono, pasting over the transition around the cut, and leaving it lossy (no Laserdisc material used).  Japanese track, here I come...

Okay, I've got the English mono track synced!  I was also able to clean up a handful of very minor issues, like that pop you heard when Arthur reaches for the Holy Hand Grenade.

So, just to recap, here are the key differences from the Blu-Ray:

 

DONE:

Cut Anthrax scene extension

Default track is lossless mono (single-channel DTS-MA with 192kbps core)

German subtitles

 

PLANNED:

Original Criterion mono commentary track (lossless?)

Original Criterion mono Japanese dub (lossless?)

Full Japanese-back-to-English subtitles

 

I imagine this will be slow going again.  Luckily I believe I'll be able to sync both remaining audio tracks with a single pass because they're from the same source.

Digital Source for the '77 Stereo Mix
Time

I've given this a listen and here are my thoughts, particularly when comparing against Belbucus' reference level LD rip:

Wow, your Fox fanfare sounds MUCH clearer.  Night and day.  Are you positive this is the right one?

Your dynamic range also seems much higher.  While in general I like this, it makes volume normalization really difficult.  What gain values have you come up with?  +8dB seems to be pretty close for "normal conversation", but that can make it loud as hell on occasion, although it doesn't ever appear to clip.  Which I suppose is just fine, I just want to make sure.

Other than that, I'm not sure I hear a lot of difference (and I'm still listening, too), but a little better is still better.  Thank you very much for sharing!

Aside from the fixes, it's pretty minor.  My goal was just to have some lossless audio sources for these movies, since I could already find lossless versions for the Star Wars stereo/mono audio.

The '80/'83 tracks from Harmy and DJ seem a little softer overall, ROTJ a little more than ESB.  I think it's more than could be accounted for from just the lossy compression though, so I think whatever track Harmy and DJ used may have had some noise reduction and/or dynamic range compression applied to it, and mine must not have as much processing--or I'm imagining things.  i.e. if I make a lossy compressed version of my files, it still sounds a hair better than the Harmy/DJ tracks (again, ROTJ a little more than ESB).  That said, I still prefer hairy_hen's lossy 5.1 ESB track over my lossless 2.0 ESB track, so it's not the best thing out there.

The ROTJ fixups are pretty significant IMO.  The major sync problem in ROTJ starts at about 47:37 (just after Luke's last scene on Dagobah) and continues until 1:38:33 (after some Ewoks jump over a log), after which it becomes a minor sync problem for the rest of the film (technically it exists but you don't notice anymore).  Maybe it wasn't until I started doing subtitling, but now I can't stop noticing how badly off the lip sync is during that bad period, and ALL NTSC-based audio has the same problem.  My version is the first version I've heard where I don't wince on and off for 45 minutes whenever Han talks (for some reason, it's always worse with Han).  That said, if you don't make a practice of watching people's lips when watching the movie, you may not notice this at all.  There's also just little audio glitches, such as at 3:23.903 when the audio just decides to go missing for 4 milliseconds.  Again, it's not huge, but you can notice if you're listening carefully.

Anyway, don't mean to down-talk my own work.  Obviously I think they're worth it for someone or I wouldn't have made them.  But they may not be a huge improvement for most people.

EDIT: I will also re-adjust all of my subtitles to match this audio.  For unadjusted NTSC audio, it'll just mean subs will be a hair late (compared to the audio--if you watch lips they'll show up at exactly the right time), which is actually perfectly fine.  I just don't want them showing up EARLY, which is awful.

I made some GOUT-synced Laserdisc audio files... (Released)
Time

They are not uploaded yet, but I’m posting here to see if there’s any interest. They are in FLAC format, and therefore huge and non-trivial to upload/download.

I have the 1980 ESB stereo audio from Darth Mallwalker’s Laserdisc capture, synced to the GOUT.

I also have the 1983 ROTJ stereo audio, also from DM’s Laserdisc capture, synced to the GOUT but with some fix-ups.  I changed the timing so that it syncs better with preservations derived from the PAL GOUT (e.g. dark_jedi/You_Too and Harmy).  This audio appears to have had many glitches (millisecond audio dropouts, pitch changes), which I fixed using audio from the '93 mix.  Technically I don’t know how many of these errors were theatrical and how many were introduced during the transfer, but they all annoyed me and would have been fixed during a proper restoration, so I still consider it the 83 mix.  All of the modifications and fix-ups add up to a few seconds of audio throughout the movie, at most.  I do not have a version without the fix-ups.

After listening to them, I’d have to say I still prefer hairy_hen’s purist 5.1 mix for ESB, but maybe there’s a hardcore purist out there who just can’t watch the 35mm cut of ESB with anything but the stereo track it showed with.  For ROTJ, I have to say I actually prefer my mix to anything else I’ve heard, but it’s entirely due to the better sync and I have confidence hairy_hen will make my current preference short-lived.

I am not an audio engineer.  I’m a novice at best.  So if someone else synced these tracks already, they probably did a better job.  Nevertheless, I personally think they sound pretty nice.

Anyway, there it is.  Let me know if there’s any interest.  Thanks to Darth Mallwalker and others for getting me access to the raw captures, msycamore and others for pointing out exactly where the sync problem was located, and hairy_hen for making this project more obsolete every minute.

Yeah, it's not a problem so much as very slow going.  I practiced LD audio sync with Star Wars, but I guess the upside of having the GOUT just be a re-release of a laserdisc master means you usually don't have to resync more than once every 10 minutes or so.  A full quality film restoration puts extra frames all over the place.

I can do it, not to worry.

Just to keep people updated, I have the Laserdisc tracks, but it will take me a while before I can do anything with them.  My plans are to make them into true single-channel mono tracks (plays from the center speaker instead of the fronts on a surround system), sync them, and probably encode them all as DTS-MA lossless tracks with a 192k core, even though, to be honest, I don't think these soundtracks really benefit from being lossless.  But why not, you know?

Then send the Japanese track off to a translator friend and make another subtitle track, and then... done!

Help: looking for... Lossless mono/stereo audio
Time

Who would be a good person to contact for checking my work?  i.e. someone with a history of being able to spot minor sync problems and glitches at scene transitions (which is where I feel most problems would be).  I have a lossy ESB encode based on Darth Mallwalker's LD rip I can share to see if I have any future in this business.  I'm afraid I'm far too easily sucked into the visuals to spot these things reliably during normal playback.

Help: looking for... Lossless mono/stereo audio
Time

Thanks. I'm trying to make/have good lossless masters for all of the original 77/80/83 audio.  Mono was easy, and I haven't downloaded 77 SW yet, but at least right now, I'm using Darth Mallwalker's 80 ESB and 83 ROTJ captures.  Did Belbucus upload original stereo mixes for ESB and ROTJ too?

The DM captures sound fantastic, but they're split into three captures apiece, making GOUT sync a little hairy.  I'm also trying to accommodate the couple-frames of sync difference in ROTJ for PAL-based preservations, which makes things a touch more complicated.
