It separates any song into 4 stems with AI: vocals, drums, bass, and other (synths/piano/guitar/strings). Each stem is its own WAV file. Vocals come from an open-source Mel-Band RoFormer model; drums, bass and other come from an open-source SCNet model.
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 separation models under the hood.

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.
Four stems (vocals, drums, bass, other) is the split the open-source models we run are trained for, and it is where their quality is strongest. We do not offer a 6-stem split with separate guitar and piano.
Yes - the result page shows individual download buttons for vocals.wav, drums.wav, bass.wav, other.wav alongside the all-in-one ZIP.

About 3,000 tokens per song, flat per-request (regardless of song length, since the separator runs once on the whole track). Free daily-pool tokens cover most use.
Spleeter is an older open-source separator. The Mel-Band RoFormer and SCNet architectures we run are newer and score well above it on the public MUSDB18 benchmark; on 50 MUSDB18 test excerpts our vocal stem measures 11.3 dB SDR. Moises is a paid subscription, while Free.ai is pay-per-use with a free daily pool.
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/.
