A Day in the Country (1936)

I suspect the Warner blu-ray sounds better than the Criterion blu-ray, given that the Criterion booklet says:

The original monaural soundtrack was remastered at 24-bit from the optical soundtrack positive at L.E. Diapason in Epinay-sur-Seine, France. Further restoration was performed by the Criterion Collection, including the manual removal of clicks, thumps, hiss, hum, and crackle using Pro Tools HD, AudioCube's integrated workstation, and iZotope RX 4.

That would be consistent with the blu-rays of La chienne, anyway.

The StudioCanal DVD sounds phenomenal -- so much more detailed and natural.
