A closer look
Free Stem Splitter: what to listen for
A free stem splitter helps you decide whether separating a song is useful before paying for a complete export. You might want to check a bass line, rehearse a vocal phrase, or explore a drum pattern. Listening to a short, representative passage is often enough to find out whether the instruments are distinct enough for that task. A free preview is particularly useful when the source recording has a dense arrangement or heavy effects.
Choose a passage that includes the instrument you care about. For vocals, include both a quiet line and a busy section with backing harmonies. For drums, include fills and cymbals, not just a sparse intro. Evaluate the preview with headphones at a comfortable level. Turning up a quiet stem can make background remnants more obvious, so also listen at the level you would actually use for practice or a rough arrangement.
The planned free tier allows one song preview per day, with a short listening segment or 30-second sample rather than a complete downloadable track. It will also have a daily site budget to keep processing sustainable. Those limits are part of the launch plan, not an active allowance in this preview. You can use the demo here without signing up; selecting a local file only checks its format and size on your device.
Work from a good source
Keep a copy of the original recording, and avoid adding compression or effects before separation. Turning a low-quality file into a larger format will not restore detail. Use the same section when comparing outputs, and listen at similar volume. The most useful result is the one that serves your next step, whether that is learning a phrase, rehearsing with a backing track, or testing an arrangement in your audio editor.
Good questions
A few things to know.
Do I need an account for the demo?
No. The original sample audio and local file picker work without an account.
What will be included for free?
The planned free offer is one song preview per day, limited to a short listening segment or a 30-second sample. Processing and allowance enforcement arrive in a later milestone.
Can I download a full song for free?
Full-track downloads are planned as a paid feature. This preview does not process or export uploaded songs.
Does selecting a file upload it?
No. File selection in this preview stays in your browser. No audio is sent to a server.
How should I judge a short preview?
Choose a busy part with the instrument you need. Check both the isolated part and the remainder for missing notes, bleed, and rhythmic changes.
