Online Stem Separator for Music Producers

Turn a finished mix into more workable musical parts. Stem separation can help isolate elements for focused practice, arrangement study, remix preparation, sampling, and production experiments.

What it does

Separates elements of a mixed track into individual audio stems.
Creates material for remixing, arrangement study, and production practice.
Runs from the browser without requiring a DAW plug-in installation.
Keeps the tool and supporting guidance together on one shareable page.

How to use it

Choose audio. Select the track you want to separate using the tool above.
Run separation. Allow the model time to identify and extract the musical elements.
Preview and export. Listen to the results and download the useful stems for your session.

Supported input

Use a clean, full-quality source file when one is available.
Browser-supported audio input is decoded by the application.
The available output stems and formats are shown in the tool before export.

Good to know

Separation is an estimate: dense arrangements, heavy reverb, and overlapping frequencies may create artifacts.
A higher-quality source generally produces cleaner isolated parts than a heavily compressed copy.
Only process recordings you are permitted to use, remix, or reproduce.

Frequently asked questions

Will the stems sound identical to the original multitracks?

No. Source separation estimates components from a finished mix; it cannot recreate the original recording session perfectly.

Why do I hear another instrument in a stem?

Instruments often overlap in frequency and space, so some bleed or processing artifacts are expected.

Can I use the stems in a release?

Technical separation does not change copyright. Make sure you have permission for the source recording and intended use.

How can I improve the result?

Start with the cleanest, highest-quality version of the track and avoid files that have been repeatedly compressed.
