Well that's a hell of a read, hairy_hen. I appreciate a good technical read and clearly, you have much more knowledge on audio theory and mixing then I do. I just downloaded the Weiss Saracon Resampler to play around with. For my next project I might try to use it for resampling before editing.
I use Adobe Audition for all my projects since I have the Adobe suite. What I do know is that when I set the project's sampling to 48,it converts the captured laserdisc's PCM from 44.1 to 48 while also converting depth from 16-bit to 32-bit. I had previously read up as to the reasoning behind changing the bit depth for editing and I saw what you wrote about it in your second post. Fascinating stuff. Now thanks to your post I know bit more on sampling part too. I am unsure as to what processes Audition uses to preform said sample rate conversion. In audition even if I keep the project to 44.1 to match the LD's audio, it would still convert the bit depth to 32 for editing. So even at its original 44.1, the audio is modified on some level (in Audition).
I have to say, I have never noticed a difference between the original 44.1 and the edited 48 that I've done. I've done a couple of A/Bs myself and failed to notice a difference both on headphones and speakers. The new, edited 48 always seems transparent to the original 44.1.
So I guess we get back to the heart of the matter, is it worth all the trouble to convert to 48? Does changing it to 48 affect the quality? Kind of the argument that Chewtobacca was making the last page. And is the audio inherently different when transformed to 48, similar to the discussion _,,,^..^,,,_ and I had about the DTS Cinema CD-ROMs. Keeping 44.1 would be "truer" to the original rip. Like I said, I can use a HTPC and play the Blu-ray with 44.1 but if anyone else wants to play it in a blu-ray player, they are out of luck. I'm going to try your recommendations, hairy-hen. See what Weis Saracon offers. Thanks for the insightful post.

What a mix everyone. Thanks to all those involved for making this available. How fitting for its 25th Bativersary!

That's my fault. I was rushing to upload a new copy and exported the entire session instead of just the LD track. That's what happens when you rush. Thanks to Jonno for pointing that out. I already fixed it, tested it and uploading it now. I will send you a new link boris.
I've just muxed the new version and checked out a few scenes - it sounds terrific so far. Thanks for putting in the hard work!
Thanks guys!

This makes me wonder, what did we use to convert that original Jurassic Park project from 44.1 to 48. It sounds perfect to my ears and on the handful of systems I've tested it on, including an actual cinema through a CP-650.
That sounds pretty cool. How did you have the opportunity to use a CP-650? How did it sound?

That's great Neonbible! I love Blade Runner. Hopefully, someone can follow your work and get both the theatrical and '92 director's cut done. Thanks to you and Buster D for that track.
