That's very much up in the air with generative AI output. The US Copyright Office has claimed so far that there's just no copyright in model output, though that's far from settled one way or the other. If there is copyright, who owns it would be yet another question. Sound is even a little trickier than other domains: the composition of a song and its embodiment in a specific recording have separate copyrights. Do both necessarily get treated the same?
