A finished song goes in. Estimated sources come back out, on their own lanes, ready to preview and export.
Paste a link to a public YouTube video or upload an audio file. ytstems validates the source, reads the audio, and prepares it for separation. Tracks can run up to 15 minutes.
The model you selected estimates each source from the finished mix. The progress log reports the real processing stages while the job runs; available stems depend on the model and the recording.
The stems open in the browser mixer. Preview each lane, set levels, solo or mute, then download an individual track, every stem as a ZIP, or a WAV render of your mix.
Different separation models target different source groups. Common outputs are vocals, drums, bass, guitar, piano, other, and instrumental — but no model guarantees every instrument its own lane, and some fold whatever is left into an other stem.
A finished song does not contain its original studio tracks. The model estimates what each source probably sounded like, so dense arrangements, heavy reverb, and overlapping frequency ranges can leave audible bleed or artifacts.
Solo, mute, and balance the available stems in the browser. Download one stem, all of them as a ZIP, or export a custom WAV mix for rehearsal and practice.

Processing time varies with track length, model choice, and available compute. The progress log shows each real processing stage while your job runs.
