Stem Splitter
Separate vocals, drums, bass, and other in your browser — then import stems into the studio library (or attach one as a dry take). Audio stays on your machine.
WebGPU isn’t available in this browser — separation still works, but it will be much slower.
Stems
Online stem splitter for producers
Need isolated vocals or an instrumental before reverse-engineering a chain? Split the reference here, then Import stems into studio — each stem lands in your Analyze library ready to analyze, with vocals/instrumental also wired as dry takes for A/B.
Does audio leave my computer?
No. Decoding and Demucs inference run in your browser. We only serve the static page and the model is fetched once from a public CDN, then cached.
How long does it take?
With WebGPU, often a few times faster than realtime. Without WebGPU, expect a long wait on longer songs — keep the tab open.
Is the stem splitter free?
Yes. Pair it with free Key · BPM, or jump into the studio for a full mix chain.
