Separate a Song into up to 12 Instrument Stems with AI

Free AI stem splitter: separate any song into up to 12 stems — vocals, drums, bass, guitar, keys, strings and more. Upload an MP3 and download every stem in minutes.

What the AI Stem Splitter Extracts

  • Vocals and backing vocals — lead voice and harmonies as separate clean tracks
  • Rhythm section — drums, percussion and bass — each as its own stem for remixing and sampling
  • Melodic instruments — guitar, keyboard, strings, brass, woodwinds and synths, isolated from the mix
  • Up to 12 stems per song — one upload returns the full set — no need to run separate extractions

How to Split a Song into Stems

  1. Upload the song (MP3, WAV, M4A…) or paste a direct link.
  2. Or pick a track from your Homiwork music — your archive is one click away.
  3. Press “Split into stems” — AI separation takes a few minutes.
  4. Download each stem from your archive: vocals, drums, bass, guitar and more.

Why Producers Use Stem Separation

Stems are the building blocks of modern music production. With a song split into individual instrument tracks you can remix a track, rebalance a mix, sample a drum groove, mute a guitar to practice over the band, or lift an isolated bass line into your own project. Classic filters can only muffle frequencies; AI source separation reconstructs each instrument, so the drums keep their punch and the vocal stays clean. If you only need the instrumental and the voice, our simpler vocal remover does a 2-stem split for a fraction of the price.

Frequently Asked Questions

How many stems do I get?

Up to 12: vocals, backing vocals, drums, bass, guitar, keyboard, percussion, strings, synth, brass, woodwinds and FX. Silent stems are dropped automatically — you only get the instruments the song actually contains.

Which files can I upload?

MP3, WAV, M4A, OGG and FLAC up to 8 minutes long, plus any track from your Homiwork music.

Can I just remove the vocals instead?

Yes — use the Vocal Remover tool: it returns the instrumental and the acapella as a cheaper 2-stem split.

Is the stem splitter free?

New users get starter energy points. A full 12-stem split is our most compute-heavy audio tool, so it costs more points than a simple vocal removal.
