Frequently asked questions

What is a stems separator?

It splits a finished mix back into its main ingredient groups — vocals, drums, bass and everything else (other) — so you can remix, practice, sample or mute individual parts.

How is 4-stem separation different from removing vocals?

A vocal remover gives you two outputs: vocals and one combined instrumental. A stems separator keeps drums, bass and other as separate files, which matters for DJs, producers and anyone practising one instrument.

Is it spelled separator or seperator?

The correct spelling is separator — one 'p'. If you searched for seperator or audio seperator, this page is the tool you were after.

Is this stems separator free?

Yes. Separation runs on your own hardware in the browser, so every tool on this site is free to use.

Are my files uploaded anywhere?

No. The separation runs locally in your browser. Your audio never leaves your device.

How clean are the separated stems?

Expect usable stems with some bleed between them — dense, loud mixes are harder than sparse arrangements. Preview each stem before downloading.

Why is there a one-time model download?

The AI model (~180 MB) is fetched once so it can run on your machine. Your browser caches it, so later visits skip the download.
