1 TB free audio storage

Pull any instrument out of any song.

Upload a track and ask for the stem you want: drums, bass, vocals, or the rest. Scarleta splits the song into separate sources and hands you clean, downloadable stem files right in the chat.

How it works

No setup, no plugins. Just ask, and get the file back.

Step 1

Upload your song

Drop an audio file into the Scarleta chat: a full mix, a sample, or a track you want to take apart. No plugins to install, nothing to set up.

Step 2

Ask for the stem you want

Type it in plain words: "give me just the drums" or "split this into stems." The AI figures out what to run. No settings, no code.

Step 3

Download the stems

Get separate stem files back: drums, bass, vocals, and the rest, ready to download and drop into your DAW.

Built-in storage

Every result is saved to your library, 1 TB free.

The files you bring and the stem separation results you get are kept in one place, so you can come back, compare earlier versions, share a link, or ask across everything you’ve stored, whenever you want.

Recipes

Make stem separation one step in a pipeline you run by name.

Chain it with other steps into a recipe you design once, then run on a single file in chat or on thousands at once.

For developers

Do this at scale with the API

Running a whole catalog? Send a batch of files to a stem-separation recipe and let a webhook call you back when each one is done.

curl https://api.scarleta.ai/v1/batch \
  -H "Authorization: Bearer $SCARLETA_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{
    "recipe_id": "rec_0002_isolate_stem",

Frequently asked questions

What stems do I get?

A song is split into a fixed set of sources: drums, bass, vocals, and other, each as its own separate audio file. Every stem comes back as a real file you can download.

Can I get just one instrument?

Yes. Ask for the stem you want ("just the drums", "just the bass") and take that file. The separation produces each source as its own track, so you can keep only the ones you need.

How much does it cost?

You pay per second of audio: $0.10 per minute, from prepaid tokens (1 token = 1 second). New accounts start with 300 free tokens, and top-ups start at $10. No subscription.

Do I need to install anything?

No. Upload a track in the Scarleta chat and ask. It runs in your browser, nothing to download.

Can I split a lot of songs from my own app?

Yes. Developers can send many files at once through our API and get called back by webhook when every one is done. See the docs.
