Split any song into four clean, perfectly synced stems.

Split any song into four clean, perfectly synced stems.
Four synced stems
Vocals, drums, bass, and other instrumentation — identified independently, not just isolated from vocals as one leftover blob.
Sample-accurate sync
Every stem is exported at the same sample rate and length as the source, so they stay aligned when dropped into a DAW.
Remix or practice ready
WAV export on Pro/Studio for lossless remixing; MP3 on Free for quick reference.
Upload a track
MP3, WAV, FLAC, or M4A, up to 30 minutes.
Choose your stems
All four, or just the ones relevant to your project.
Preview, then export
Preview each stem individually, then export as a synced, same-length batch.
How it works, under the hood
Unlike a simple vocal remover, which only distinguishes "vocal" from "everything else," stem separation identifies four distinct instrument categories independently — trained on multi-track studio masters where each instrument was recorded on its own channel.
What it’s good for
- Remixing or re-arranging an existing track
- Isolating a bassline or drum pattern to study or sample
- Creating a backing-track-only version for live performance
- Practicing an instrument part with the rest of the mix intact
See below for a workflow-specific guide if you’re building remixes for DJ sets, where the requirements go beyond clean separation alone.
- Why only four stems instead of every individual instrument?
- Four stems (vocals/drums/bass/other) is the industry-standard split that balances separation quality against how many categories a model can reliably tell apart.
- Will the stems be perfectly clean with zero bleed?
- Separation quality depends on the original mix — a well-produced studio track separates more cleanly than a dense, heavily-compressed master. Expect professional-grade results, not laboratory-perfect isolation.
