Vocal Remover & Instrument Isolation

Split a song into its parts. NutifAI's AI stem separation pulls apart vocals, drums, bass, guitar, piano, and other instruments so you can download an instrumental mix, an isolated vocal, or any single stem.

Upload a song — it's free to start

Supported formats: MP3, WAV, FLAC, M4A, AAC, OGG (Max: 50MB)

What you get

  • Removes vocals to create an instrumental (karaoke) version of a song.
  • Isolates the vocal line on its own — useful for a cappellas and vocal practice.
  • Separates individual stems: vocals, drums, bass, guitar, piano, keys, strings, and other.
  • 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.

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.

Vocals, drums, bass, guitar, piano, keys, strings, and an 'other' bucket, plus a combined instrumental (everything except vocals).

Every account starts with free credits (1 credit = 1 second of audio). Optional credit packs support the service once the free allowance is used up.
