Audisect — free AI stem splitter in your browser

Split any song into vocals, drums, bass, guitar and other stems. Audisect runs the HTDemucs AI model directly in your browser, so your music is never uploaded. Mix the stems, then export WAV, FLAC, MP3 or OGG.

Frequently asked questions

Is Audisect free?

Yes. Audisect is free to use with no account and no limits on the number of songs.

Is my music uploaded to a server?

No. The AI model runs inside your browser, so your audio never leaves your device.

Which stems can Audisect separate?

Up to five: vocals, drums, bass, guitar and other. You can also pick just vocals and an instrumental.

Which file formats can I export?

WAV (16-bit, 24-bit or 32-bit float), FLAC (16 or 24-bit), MP3 (128 to 320 kbps) and OGG Vorbis.

Which browser works best?

A recent desktop Chrome or Edge is fastest. Firefox and Safari work too. The first run downloads the AI model once (about 140 MB) and keeps it for later visits.
