After discovering the fantastic world of myspleen, my creativity awakes suddenly and said "I want to do more..." (regarding my next project, "SET ruLes")... so, I downloaded the 1997 SE DTS audio tracks, and began to experiment with them...
The first, simple thing I've done, is this: I took the first ANH reel WAV PCM 44.1khz 16bit files - six discrete channels - then merged them into a single WAV PCM converted to 48khz 16bit, and finally reconverted them to DTS 5.1 48khz 16bit 1536kbps.
The result track seems almost the same of the original PCM WAVs (say, 99%?) accordit to the Audacity comparison "by eye" I made, apart a little volume reduction of the LFE (I think less than 2dB) due to the audio converter.
So, here you are the file - sendspace (warning: 218MB); is there someone who'd like to test it on his DTS audio system, and tell me what does he think (especially if the channel positions are right - this is my main concern)?
The original file must be at 24fps, where the NTSC 1997 version should be at 23.976fps, so take it in account if you mux the track with your video... at the end of the reel, the audio would be desynchronized for 28 frames, a little bit than a second.
A lot of this has been covered in some detail both earlier in this thread and also in this thread. We have confirmed that the files are 24fps, and I have already syncronised the whole SE trilogy to a 24fps source and converted them to 23.976 with as little processing as possible (by manipulating playback sample rates to match the frame rates before resampling the audio to 48KHz). The audio as is presented in the torrent on MySpleen is a bit rough around the edges as it is, and the LFE is far from perfect as there is no discreet LFE channel on the DTS discs, I produced it very quickly from a low-pass filter by following the DTS theater spec to know how to reproduce it, but I'm convinced those results are inferior for home systems; I've developed my own preset for a more suitable LFE for my own syncs that sounds great on my THX system.
My syncronised files will be made available to you should you wish to use them, they have all be adjusted manually, using no time stretching tools or programs other than Sound Forge and Adobe Audition so each step of the process has been accounted for. Call me a purist and a control freak, but I've grown to dislike automated conversion software! The methods that I have used are the result of discussion with other forum members in the audio thread I've linked to above, check it out for an interesting read!
If this resulting file is right, I could use the DTS soundtrack for my next project... yes, I know that one of the [OUT ruLes] project statement said no digital source could be used, but, hey, rules are made to be broken! (^_^) and, by the way, those DTS tracks were meant to be used only in theaters, and not released for home use, so the rule is only half broken... well, the solution is ready: as this will be the [SET ruLes] project, the only thing I have to do is change that rule, is that simple... (!**3)
I have been trying to capture some laserdiscs for this very purpose although I'm hold because I'm having to shop around for a new IPS monitor for colour-correction as my old one was too small and so ended up on my old retro-gaming system! I've no doubt you could achieve captures that are superior to anything I can produce due to your range of players.
There is great discussion about frame accuracy earlier in this thread and if you could capture and produce video tracks that conform to these numbers (reel change points, etc) I will gladly provide my synchronised theatrical DTS, Laserdisc 5.1 and 2.0 files to you for a release (yes, I've been very busy and done all of them to conform to the 'standards' set in this thread). PM me again if you're interested and we can work something out.
