Moises

Pulling a vocal or a drum part out of a finished song used to need the original session files. Moises is an AI music app that does it from the audio alone: it separates a track into stems, removes vocals, and lets musicians remix songs.

The category also covers chord detection and AI mastering, so the same app can help you work out what a song is playing and polish your own mixes.

Moises runs on the web, iOS, Android and desktop, which is handy if you practise on a phone and edit on a computer.

Processing happens in the cloud, so you need an internet connection.

Separation is described as accurate, but it relies on AI, so some tracks will come out with bleed or artifacts.

The free version may have limits on what you can do.
