AudioLDM is trained on youtube clips and BBC Sound Effects Library, which are not necessarily compatible with CC0. AudioLDM's release of the model is based on the UK copyright exception of data for academic research. CC0 allows for use outside of academic research. I was also not able to determine if the AudioLDM team was ever able to confirm or refute the data-related copyright issue they were facing.

The code for it is licensed CC-BY-NC-ND, but there is no mention of what license or terms of use the output falls under. I would rather not assume output falls under the same license, but in the absence of a clear set of usage terms for the output, the license of the code has to be assumed until we know more.

I'm aware of that article, thank you. It only says they won't register art as copyrighted that have been AI generated. It doesn't say AI art won't violate other existing copyrights.

My quesiton has been: Can AI art violate someone else's copyright? 

The answer I keep getting back is: It's fine; AI art can't be copyrighted... which does not answer the question.

That's like saying:

Me: Are there any stolen parts in this car?

"Free"-car-donor: Oh, it's not really possible to "steal" this car; I'm giving it away for free. I built it myself.

That doesn't mean it isn't using stolen parts. Using the car, even though it is given away for free, even though it was honestly built, will still get me in legal trouble if the parts were illegally sourced. Yes, I am aware that GANs do not take "parts" from other art and peice them together. Stop typing your "um, ACKCHYUALLY-" reply and try to follow along:

Me: I didn't ask if I could steal it from you. I want to know if you used stolen parts to build it.

"Free"-car-donor: Well, I paid for the parts, so no I didn't steal the parts.

Me: Again, I didn't ask if *you* stole the parts. Who did you buy the parts from? 

"Free"-car-donor: I didn't catch his name, he was too busy glancing over his shoulder all the time. He seemed really nervous about the transaction. He had a friendly smile though. And he was well-dressed, too. He even wore a hat and tie... and a mask... and he kept saying 'Robble robble'. Here's a picture of him. I'm sure he's an honest car-parts salesman who's prices just happen to be 75% below the market rate.

AI art is not copyrightable, but it may still violate the copyrights of others. IMHO AI stuff is probably fine to use. But I'm not a lawyer, nor is anyone else on this site to the best of my knowledge. Yet people who ARE lawyers are saying "yes it could be a copyright problem". Not that it IS a copyright problem, but "could be" is too much uncertainty for OGA. This doesn't mean you can't use such art in your projects. It just means OGA can't share it until we're certain it isn't going completely screw over our users downstream.
