There is a new strategy I noticed recently. My wife was listening to an 80's "radio station" (autogenerated playlist) on YouTube Music and I noticed that some of the songs sounded a bit odd. It took me a bit but I figured out what these scammers are doing.
- Use Abelton to separate the vocal stem from the original track.
- Use ReVoice to change the vocals to an AI altered one that is almost identical to the original. ReVoice is a plugin that modifies "your" vocals instead of generating new vocals. The result is a vocal track who's artificialness is difficult to detect by most.
- Replace the original vocal stem with the ReVoice one.
- Upload it as a "cover" or "vocal cover".
- Profit.
Please note that the song and the vocals remain exactly the same but the voice is just ever so slightly different. I have no idea how this is legal.
