Sounds.studio is a web-based music AI system that has a number of tools I haven't tried out yet. The only one I've played with is the "Split stems" tool, which isolates individual tracks from any song you drag into it.
I tried it with The Beatles' 1966 song, "And Your Bird Can Sing," and it did an impressive job of isolating the drums, bass, guitar, and vocals.
I also tried it with a recording I made in a band I was in back in the 1980s. It was fun to hear my isolated bass track.
If anyone tries the other features here, please share in the comments.
