I have been breaking my head on this, as the BFI Blu-ray and the newly released remastered version UHD Blu-ray from Criterion has muffed audio. If you notice the specs below

1. Criterion Blu-ray 1080p -

The audio present with the Old school Criterion Blu-ray is the best, so good that it actually beats the Criterion DVD. You may notice a low pass filter here, but the CC DVD has more of it. Probably the only reason of it being the best audio choice as of now. The depth in dialogues are much clearer and has details very noticeable.

2. Criterion DVD -

Could have been an easy win, but due to the low pass filter being very significant and lying on the audible range, One could easily differentiate in the audio loss and quality.

3. Criterion UHD -

I'll keep this as simple as possible, Audio is botched, you could find that out from the score at the samples provided below. Went under heavy noise reduction and has details missing!.

4. BFI Blu-ray -

The audio presented in the Blu-ray is of 2.0, but after the inverse check it's out to be the mono!! So downed to 1 channel for a better reference.
Well, the same as above, the only difference is that there is a tempo change and a possible shift.

5. ESC Editions (France) UHD Blu-ray - Same as above.

Samples - https://mega.nz/folder/tyoDjLwb#OU0-TuzpxtCtfw2tbL7MAA
The samples consist 10 minutes audio of BFI, Criterion Blu-ray, Criterion UHD Blu-ray. The audio/volumes are matched at the same levels in-order to get a taste test


Regards

6. BFI PAL DVD

Thanks to M.A got my hands on the BFI PAL DVD, processed the audio to match the sound levels, and after isolating the frequencies for both criterion and BFI PAL DVD can confirm the hiss present in the BFI PAL DVD doesn't really add up any extra details. So more on after Criterion BD still is the best audio.

So I managed to sync the Criterion audio to the Criterion UHD, France UHD & BFI Blu-ray. The edits had to be done manually as sources were not frame accurate. (frame drops etc.)
If you want to check it out, PM me for the link.

Curious how would one do this analysis? By "subtracting" Criterion's signal from the BFI PAL DVD?

You can isolate frequency using frequency selection tool on izotope
