It would be a pretty cool project.

I found out the hard way though that some modern audio denoisers/etc use something similar. One of my favorite youtubers audio has the exact same audio signature, even though it's clearly not AI generated. Eventually he mentioned that he was using a new AI cleanup tool and it clicked. Since then I've noticed it creeping into more and more videos. Linus Tech Tips uses it on some videos, for example.

So even for people who are sensitive to it, the false positive rate is now probably very high. It's making me a little crazy that other people don't seem to be bothered by it.
