It separates any song into 4 stems — vocals, drums, bass, and other (synths/piano/guitar/strings) — with AI. Each stem is its own WAV file. Same Demucs model used by Moises and Splitter.ai.
Vocal remover keeps everything except vocals (instrumental output). Isolate vocals does the opposite (acapella output). Song splitter gives you all four stems separately so you can mix and match. Same Demucs model under the hood.
A ZIP archive with 4 WAV files: vocals.wav, drums.wav, bass.wav, other.wav. Each is the same length and sample rate as the input, so they layer cleanly when re-mixed in a DAW.
MP3, WAV, M4A, FLAC, OGG, AIFF, and most common audio formats. Max upload 50 MB (about 5 minutes of MP3).
6-15 seconds per minute of input on our A100. A 3-minute song takes about 25-40 seconds.
Excellent on well-mixed studio tracks — vocals are nearly perfect, drums and bass very clean, "other" sometimes has a bit of crosstalk from neighboring stems. Lo-fi recordings, live shows, or heavily-effected tracks produce noisier separations.
Demucs uses a 4-stem decomposition (vocals/drums/bass/other) — the most popular pre-trained checkpoint. 6-stem variants exist (vocals/drums/bass/guitar/piano/other) but quality drops noticeably; 4-stem is the sweet spot.
Yes — the result page shows individual download buttons for vocals.wav, drums.wav, bass.wav, other.wav alongside the all-in-one ZIP.
Personal use (practice, study, remixes for non-commercial enjoyment) is generally fair-use OK. Sampling, publishing, or commercially releasing stems requires the song's sync / mechanical / sample license. You're responsible.
About 3,000 tokens per song, flat per-request (regardless of song length, since Demucs runs once on the whole track). Free daily-pool tokens cover most use.
Demucs (Meta) generally beats Spleeter (Deezer) on vocal-isolation quality and is comparable to Moises on the rest. Free.ai uses Demucs at the same quality tier as Moises Pro, but without the subscription.
Yes — POST audio to /v1/audio/separate/ with `mode=stems` to get all four stems back. Or specify `mode=vocals` / `mode=instrumental` for the single-stem variants. Docs at /api/.
