> Generative models synthesize sound mathematically. These synthesis methods leave unnatural dips, specific spectral noise profiles, or phase alignments that rarely occur in real, human-recorded audio
Ultimately this isn't really solvable without a way of marking audio with a verifiable signature that it was produced by a specific human, with some kind of reputation algorithm.
You really just want your users, who hate AI, to see a big "REPORT AI" button they can click. The problem you are trying to solve is the perception among your users that your platform is dominated by AI slop. So at the end of the day the only thing you actually have to figure out is what your users think is AI slop, have a quick trigger on un-popular stuff, and basically never enforce on popular stuff unless there is actually some controversy.
