Vocal Remover & Instrument Isolation
Split a song into its parts. NutifAI's AI stem separation pulls apart Bass, Drums, Guitar, Piano, and Vocals so you can download an instrumental mix, an isolated vocal, or any single stem.

What you get
- Removes vocals to create an instrumental (karaoke) version of a song.
- Isolates the vocal line on its own — useful for a cappella versions and vocal practice.
- Separates individual stems such as Bass, Drums, Guitar, Piano, and Vocals and other supported parts.
- Uses modern separation models (BS-RoFormer, with Demucs as fallback) for clean splits.
- Feeds isolated stems into transcription, so sheet music can follow a single instrument.

- 2 The AI analyzes tempo, key, and instrumentation, separating stems when needed.
- 3 Processing runs in the background — you can watch the progress live.
- 4 Download the instrumental, the isolated vocals, or any individual stem as audio.
Frequently Asked Questions
Yes — upload the song and pick what to isolate. Separation quality depends on the mix; modern, well-produced tracks usually split cleanly, while live or lo-fi recordings can leave audible bleed between stems.
No separation is perfect. Expect slight artifacts, especially on instruments that share frequencies (e.g., piano vs. guitar). For practice, karaoke, and remix sketches the quality is typically more than enough.
The configured stem targets, plus a combined instrumental (everything except vocals).
