Question: Is there a tool that can isolate vocals from any audio source and provide royalty-free results?

If you want a tool that can separate vocals from any audio source and that offers royalty-free results, Kits is a standout for its suite of AI audio tools. Kits has a vocal remover tool that lets you pull vocals out of any audio, and it comes with a royalty-free library so you can be sure your output is legal and safe. The service has a host of other creative tools, including voice cloning, AI singing generators and mastering, all accessible through an interface.

Another top contender is Cryo Mix, which offers an AI Audio Separator that can isolate stems like vocals, drums and instruments out of a single audio file. That, combined with its AI mixing and mastering tools, means you can create good-sounding audio with relative ease. Cryo Mix also offers a range of royalty-free music options, making it a good choice for beginners and pros.

Musicfy is another powerful tool that lets you create music with different voices. It's got stem splitters for isolating tracks, and it offers royalty-free music albums you can use in your projects. Musicfy's interface is designed to make music creation easy, even if you don't know much about music. The service offers different levels of subscription plans depending on your needs and budget.
