Re: @Stumpy- MiniDisk? Bah!
Of all the uses for AI, I think the creation of a perfect recording using multiple references of varying quality, would make all the effort seem worthwhile.
Imagine your old 78 with it's scratches, hiss, rumble and poor studio recording being used as the primary data source, and then add layer upon layer of data, such as what a double-bass sounds like when it is recorded in a 1930's studio and what it sounds like in a 2019 studio.
Throw them all together and let the AI produce a pure audiophile experience of the original version, as it would have sounded if the artists had quantum leaped into a 21st century studio.
Ziggy thinks there's a 94% probability that someone has already perfected the means to reissuing yesteryears music to a new fan base. Sadly it involves messing with it until it is barely recognisable.
