I work with a system which extrapolates data in the frequency domain to reduce noise in medical images and then doubles the images resolution in the x and y direction (so 4x the pixels). It’s absolutely amazing.

It’ll be interesting to see if audio ever gets a similar treatment and in what areas it can be applied.

Noise levels in contemporary audio is vanishingly small, and has not really been the target of any audio technology for quite a long time.

Of course, restoration of older recordings is a separate issue, and that technology is 20-30 years old, at least (and very, very good).
