The problem it solves
Editors and creators often need just the instrumental or just the vocal — for a music bed, a remix or a clean dialogue mix.
Most stem splitters are websites: upload the song, wait in a queue, download the result. That’s slow, and not ideal for unreleased or client audio.
How it works
- 1
Drop a song
Add an audio file from your Mac.
- 2
Choose the split
Vocals and instrumental, or more stems.
- 3
Separate locally
Processing happens on your Mac using Demucs.

Export the stems
Each stem saved as its own file, ready for your timeline.
