Woman in the Dunes (1964)

Both being from the same master, the Criterion BD and DVD audio tracks are generally pretty similar; however, there is some additional noise reduction on the blu-ray audio, along with some needless low-frequency filtering.

The drums in one scene no longer pound with as much force as they did on the DVD, and some dialogue is now more muffled. Interestingly, the sound of wind in the final third or so of the film is now a bit louder--possibly EQ on the BD, but it could also have been attenuated somehow on the DVD. Either way, I still prefer the 192 kbps AC-3 track on the DVD (synced with a +1877ms delay).
