How do I separate a song into stems for free?
The answer
Upload the song to an AI stem splitter such as the SongUp AI Stem Separator below. Choose 4 stems (vocals, drums, bass, other) or 6 (adding guitar and piano), and download each stem as WAV. It runs the HTDemucs model in your browser, so nothing is uploaded; it uses no credits but needs any paid SongUp AI plan. For a completely free option, the desktop app Ultimate Vocal Remover runs the same kind of model.

No credits are needed and there is no per-song limit, but the Stem Separator needs any paid SongUp AI plan. Every plan unlocks it. For a completely free option, use the free desktop app Ultimate Vocal Remover (UVR5).
What is HTDemucs?

Why is there bleed between stems?
