Since the losses in the analog conversion process cannot be determined exactly, the model is bound to add some noise to the converted audio. Video has more spatial data to guess the color and motion so it's easier in practice. The unconverted sound may be crisper and has more details but, there's no guarantee that they're the original details so, it won't be the original recording itself.
Light pollution adds noise to telescopes too. From a sky where you can barely see 4 stars you can pull detailed colored images of deep space objects. Perhaps you have to play the media a few dozen times and do the media equivalent of frame stacking to see through the noise. It's also quite possible no ML would be needed. I don't think frame stacking uses ML. I wouldn't be surprised if you could play a song on repeat…
The random noise in photography is emitted from the sensor itself and has a distinct profile. This profile can be extracted with certain procedures and can be used as a single pass NR process with very high quality results (Darktable's Profiled NR does this if the camera's profile is generated/bundled). Also Subtractive NR does something similar. After the exposure, a closed curtain exposure is taken with same shutter value and that image is subtracted from the first image. Since it's a per-sensor process, its quality is very high too.
Light pollution is also somewhat similar. It's a specific wavelength, emitted from ground to sky (so its gradient can be known) and can be filtered out relatively easily with stacking and other RAW processing (assuming your image has enough bit-depth and headroom in both highlights and shadows). There are also new filters which directly filter this kind of pollution IIRC.
Stacking does something similar. Pixels with high consistency is kept, low consistency is discarded so you get a clean image. Sorry, I don't know its exact math since I don't have a tracker and don't take many astro photos.
However, in an analog recording you have incomplete information and you want to put it back via ML, which is basically a very educated guess in this case. A well tuned and trained ML model would probably put back sensible or semi-sensible details back but, it cannot guess and re-generate the missing parts with 100% accuracy.
So at the end of the day, in photography, you have the ability to get the complete information (via stacking or subtractive NR or by cooling the sensor a great deal) however, in an analog recording, you don't have the complete information. Especially if you record it via a speaker to microphone path (since they're not ideal reproducers).
We may go to the sounding characteristics of analog audio pipelines and vinyls from there but, that's another rabbit hole I'd rather not dive now.

Only in the eyes of the law. The RIAA can no more stop people from downloading YouTube videos than the DVD CCA could stop people from cracking CSS. Pirates haven't lost yet, only ever been delayed, and rarely by all that much. This battle has been going on since audio tape recorders and VCRs became a thing, and at some point various industries will have to accept copying as part of reality, and that it is incumbent o…
No they're winning slowly. Fifteen years back everyone I know could easily download mp3 from various p2p applications. But now the present generation of youngsters seem to think it is Spotify/Amazon or nothing. They haven't even heard of p2p. Similarly Netflix is slowly eating away at torrenting. The platform owners can and will tighten the noose gradually. End users and hackers have much less power than they like to…
If any big exclusive content music services pop up we'll be right back on the pirate bay for everything again

As does telling your browser to display the desktop site instead.

Although I get your point, there is an important difference between those two though. Once you've bought the CD you can listen to it forever, that is not true for subscriptions - _that_ is why they are cheaper. I kinda use a hybrid - I discover new music on free tier of subscription services, and once I identify songs that I love, I buy them from iTunes DRM-free. I'm just afraid that option won't remain there forever…
You said it yourself - now you can pay $1 for 1 song and own it forever. Still a better deal than what we had back in the CD era.
Depending on how extensions go, your children and grandchildren may have to re-pay to listen to your collection.
Has anyone ever experimented with reversing the analog loop with machine learning? Generating the training data would be easy. Play audio files through a speaker and record the speaker with a microphone. Then you have the original and the analog recording. Train the machine to reverse the process. Now you can grab high quality audio from any source. Same could be done for video, but would require a more elaborate set…
> to see all advertisements I suggest to also click on all possible advertisements then not purchase anything (just ignore whatever tab was opened by your click). If millions of people did this daily, it would break the web advertising model very fast since advertisers pay per click. I don’t know what would replace it, but maybe something better than what we have now. Maybe not.

Wait, how does that even work?
The downloaded videos likely have time constraint applied to them that can be updated when the app connects to the Internet. I don't think the downloaded videos can be played outside of the app.

It makes far more sense to grab a line-out feed rather than using a speaker and a microphone. Otherwise the positioning of the microphone and the exact voice coils of the speaker and microphone would all have a dramatic effect on the EQ curve of the audio, to say nothing of stereo or the ensuing phase issues that crop up when recording audio in real life

Don’t forget building rockets to go to Mars.
Which is great, unless your entire country is swallowed up by social and educational problems that enable a corrupt, fascist government, or if deforestation and despeciation continues at its current pace. The technological gains from rockets, solar panels, and electric cars won't matter then. Figure those things out, and then a trip to Mars won't look like a sci-fi futurist's vanity project.
Hell, even just “make successful electric car brand” is more than I was expecting when I first heard about Tesla, and even if they do as well as their current market cap implies, they’re still not going to solve climate change by themselves — and that’s one of several causes of the current mass extinction.
