Decided to sync a few tracks for this movie

1. 2.0 Original Dolby Stereo Mix

Sourced from the 1999 DVD (thx @stwd4nder2), To my knowledge and according to my research this DVD has the highest quality version of this mix. Available in 16-bit 48kHz FLAC 2.0

2. 5.1 & 2.0 Sensurround Mix

Sourced from a bit-perfect capture of the THX AC-3 Laserdisc [8760-85]. There's a sync of this already on Internet Archive however the one review on the page states that the track is not properly synced so I went ahead and resynced it, Available in 16-bit 48kHz FLAC 5.1. Due to the limitations of AC-3 Laserdiscs the 2.0 PCM track has considerably higher frequency detail than the 5.1 AC-3 track, since I use Sony Vegas for my syncing it was as easy as replacing the AC-3 with the stereo track. Available in 16-bit 44.1kHz FLAC 2.0

3. 5.1 Sensurround Mix (Decoded Stereo + AC-3 LFE)

Like my T2 syncs I decided to do a highly experimental audio track for this film. Using my sync of the PCM stereo version of the Sensurround mix as a base I ran the track through foobar2000's FreeSurround plugin to decode back to a 5.1 surround track, from there I added the LFE from the discrete AC-3 5.1 and made the decoded surround channels duped mono. This should be the version of this mix with the most high frequency detail. Of course using a Dolby Hardware Decoder would be much better than a software plugin but as I don't have access to said equipment this is the best I could do to execute this idea and for that it should be noted as highly experimental. Available in 16-bit 44.1kHz FLAC 5.1

hey all! verdi here

The only copies of the Dolby Stereo mix of Alien I can find suffer from a variety of issues that I speculate might be inherent to the mix itself but I'm not sure

I have a bit-perfect capture of the [1090-80] CBS FOX Laserdisc which infamously has poorly mastered sound

"The Dolby A noise reduction used on the master tape was not decoded on one channel, leading to the odd sounding release. This was a problem with many LaserDisc titles in the 80's and was due to sloppy work at the mastering plant. Needless to say, the undecoded Dolby A leads to a channel imbalance which varies with level (due to the way Dolby A works) and prevents any proper decoding of the Dolby Surround encoded audio"

I also sampled the PCM Optical track from the 35mm scan and it too was off balanced ontop of having typical optical audio issues such as popping and excess noise.

The only release that has the Dolby Stereo mix that I haven't checked is the 1999 DVD, which I do not have access to. If anyone on this forum has a copy of the disc they'd be willingly to share I'd be more than grateful to sync it to the 4K. Cheers and peace for now

Hey everybody.

I'm happy that I found this site. Thank you!

I mentioned in my post for the T2 SE LD audio that I was working on my own T2 custom. I decided since a bulk of the project was audio syncs I would just release the syncs I did for the Theatrical Cut. I synced a total of 3 tracks to the 4K 35mm Scan.

NOTE: All tracks listed are synced to SPECIFICALLY the 2160p 35mm Optical CC WB at a frame rate of 23.976. The scan is at a frame rate of 24.000, the easiest way to adjust the frame rate is to use MKVToolNix and type in "23.976" into the "Default Duration/FPS" section on the video. You can also speed the audio back up to 24 via eac3to.

1: Original CDS Mix
Sourced from the DTS track on the 2003 Pioneer JPDVD, Available in 24-bit 48kHz FLAC 5.1

2: Original Dolby Stereo SR Mix
Sourced from a bit-perfect capture of the US WS Laserdisc, Available in 16-bit 44.1kHz FLAC 2.0

3: DTS Headphone:X Remix
Sourced from the 2015 US Blu-Ray. I thought this track was rather impressive so I decided to sync it for my project. Available in 24-bit 48kHz FLAC 2.0

3.5: Custom Dolby Atmos "Bed" Upmix
As an experiment I decided to upmix the Headphone:X track to 7.1.2 Dolby Atmos, Do note this track is highly experimental and will not provide a full Atmos experience. Available in 24-bit 48kHz TrueHD 7.1 Atmos 
No Longer Available

As per usual all audios are freely available to any account new and old. Cheers!

Had this laying around on my mega account. I personally synced this track because I was looking for a version of the 5.1 mix that didn't have the missing line and could not find a rip of the DTS-HD HR from the Lionsgate BD. I later found out that this track from the DVD actually has less reduction than the Lionsgate 5.1 and sound much more natural compared to the LD Dolby Stereo mix.

Available in FLAC 5.1, if any alternate formats are needed state in the PM, freely available to all members new and old

So excited to discover this community.  I've been interested in learning more about the process of these restorations.  I have a background in editing in the animation industry, but don't have a lot of nitty gritty technical knowhow with regards to manipulating already created assets.  Looking forward to diving in and reading about everything and asking my questions!

I am currently working on my own personal T2 project and since I don't have plans to share it (mostly because I don't feel it's unique enough to warrant a projects page). 
I thought I'd at least share this as I didn't see anyone post about as most projects for this film focus on the Theatrical Cut.

I have synced a bit-perfect capture of the T2 Special Edition Dolby Surround LD mix to the 2015 BD. I've heard this mix is quite beloved and listening to it for myself it's a quite a powerful stereo track. Probably doesn't need to be said but this is synced to the 153 min Special Edition and not the 156 min Extended Special Edition.

Hi! I'm interested in LOTR restorations

Inspired by PhysDigiCollCorn's Reborn and noogai3's LD audio syncs, I decided to do one for Toy Story 2 by ripping the audio from the Ultimate Toy Box DVD and the full screen version from the standalone disc (since the latter contains bloopers) as these are Dolby Digital EX encoded and I heard that it might be closest to the original theatrical mix released to theaters.

One minor note, the DVD is missing a frame of footage during the scene where Utility Belt Buzz laments the "loss" of his "father" which I have to add a millisecond of silence just to keep up with the Blu-Ray copy which was used as a reference for syncing.

Speaking of the Blu-Ray release, the AC3 track is synchronized to the 2010 copy as current versions cut out the "casting couch" gag from the blooper reel in the light of the sexual accusations towards John Lasseter (a disgraced co-founder of Pixar). Also, the audio needs to be delayed by 17934ms with MKVToolNix as the Blu-Ray uses the 2009-present re-release masters (in which the Pixar variant of the Walt Disney Pictures logo is replaced by the 2006-2022 CGI castle logo). I might do an audio hybrid version with the edited version of the credits though if I can get my hands on the current 4K and/or Blu-Ray releases)

Even though the DVD's claim that the audio is encoded with Dolby Digital Surround EX, MediaInfo doesn't specify that so I'd assume you have to force it into Dolby EX with a receiver if it has that option? I could be wrong though.

The audio is losslessly combined with FFMPEG by using the concat filter.
