If you want a quick way to pull out vocals or instrumental music from an audio file, Vocali.se is a good choice. This free online tool uses machine learning and artificial intelligence to separate vocals from any song or audio file in a few minutes. There's no software to install and no account to create, so it's good for whipping up karaoke versions or isolating specific audio parts.
Another good option is Fadr, a web-based site that offers a collection of AI-based music tools. You can pull out vocals, bass, drums and melodies from audio files, and also get tools for remixing and mashups. With free and paid tiers, Fadr offers a lot of options for musicians and producers who want to take their music to the next level.
If you're looking for more advanced tools, Cryo Mix has AI-based mixing and mastering abilities. Its audio separator tool can pull out individual stems like vocals and drums from a single audio file, and it's got full mixing and mastering abilities, too. The site is designed to make high-end audio production accessible to anyone, not just experts.
RipX DAW is another powerful option, in particular for producers and DJs who need more advanced stem separation and editing abilities. It lets you edit notes and replace instruments, for example, so it's good for creating and manipulating audio. It requires a beefier computer setup, but if you're a serious user, the results are well worth the cost.
