One idea. Four ways to hear it.
Choose a layer, then press play. Nothing plays automatically.
An original, synthesized 8-second loop. These prepared layers demonstrate mixing, not AI separation quality.
A smaller toolbox. A better starting point.

01 / AI STEM SEPARATION
Stemix
Separate vocals and instruments into 2, 4 or 5 stems. Listen closely, adjust the balance, and save a track or your whole mix.
02 / UNDERSTAND YOUR AUDIO
Audio Inspector
Before you process: check duration, decoded sample rate, channels and sample peaks. See the waveform and understand what the numbers mean.
A few steps. Plenty of possibilities.
Choose what you need
Try 2 stems for vocals and backing. Choose 4 for bass and drums, or 5 when you need a separate piano estimate.
Listen before you save
Compare the separated tracks, adjust their levels, then export a stem or Mix. Separation can leave audible artifacts.
Make sense of what you hear.
Product-specific guides with real settings, trade-offs, and things to check when a result is not what you expected.

01
A backing track for practice
Begin with the vocal/backing model. Check the chorus for remaining vocal reverb before exporting.
02A closer listen to the rhythm
Start with 4 stems and lower the drums or bass. Keep the original nearby as a reference.
03A recording that needs a check
Inspect the waveform and sample peaks before deciding how to export or mix.
Good questions, straight answers.
Is it really free?
Yes. Separation, mixing, local history and MP3/WAV exports are free. You do not need an account, credits or a subscription. Ads help support the site.
Does my audio leave my device?
The tools process selected audio locally. Models and components are downloaded, but your audio, filenames and results are not sent to XSL. Advertising and site delivery make separate network requests.
What are the current limits?
Stemix accepts files up to 256 MB and audio up to 10 minutes. Processing also depends on available memory and a compatible WebGPU browser. Audio Inspector has a 64 MB limit.
Will a separated track sound like the studio original?
No guarantee. These are model estimates of a mixed recording. Reverb, overlapping instruments and lossy compression can leave bleed or a watery texture. Read the guide on separation artifacts.
Which browser should I use?
For Stemix, start with an up-to-date Chrome or Edge with WebGPU and hardware acceleration. Audio Inspector uses the browser’s audio decoder and does not require WebGPU.
Can I use someone else’s song?
You are responsible for permission to process and reuse a recording. Separating it does not grant ownership or permission to publish. See our terms and use content you are authorized to work with.
A good idea starts with a little listening.
No account. No upload queue. Just your browser, your audio, and room to experiment.
