Well, the problem is that on these old cylinders there is quite a lot of static noise, and then in addition sometimes a sort or repeating thump every time the cylinder rotates. When you then remove the static and thump, you take some of the fullness of the original voice. I do not doubt that those with better equipment than myself would get a better outcome. But it is not easy. They have a recording of both Queen Victoria and Lord Tennyson. And it is very hard to extract something you can be sure is genuine. I hope these Ai services would set up some template for this. It should actually be quite easy, as the noise profiles on all of these are almost identical, and that subtraction process would be much better. It could be very interesting to hear the oldest voices on wax cylinder. I did this because enjoyed the song, probably because I also used to enjoy drinking :) Some people like other things, that's ok...:)
