Free AI stem separation online — split any song
Stem separation takes a finished song and splits it back into its building blocks. VocaLoft uses AI to separate a track into vocals, bass, drums and melody, so you can solo a part, drop an instrument, or build something new — entirely in the browser.
Split a song into stems →What is stem separation?
A normal audio file is one mixed-down stereo track. Stem separation reverses that: AI listens to the mix and reconstructs each instrument as its own track (a "stem"). Once separated, every stem has its own volume and mute, so the song becomes fully interactive.
How to split a song into stems
- Paste a YouTube link or upload a file into VocaLoft.
- AI separation runs automatically and returns four stems.
- Toggle and balance each stem — mute, solo or lower the volume.
- Export or save the mix you build.
What you can do with stems
- Mute the vocals to make a backing track.
- Solo the drums or bass to practise your instrument.
- Keep just the vocal as an acapella.
- Combine stems with a key and tempo change for rehearsal.
For teachers: isolate the melody or mute a part so students can play along —
