Four stems, one aligned decision
Preview the same source as vocals, drums, bass, and other before choosing a full export.
Four-stem AI workflow
Choose a 30-second preview from your song, then compare vocals, drums, bass, and other before unlocking the complete package.
Four true stems
Vocals, drums, bass, and everything else, as separate files you can drop straight into a DAW.
Trackable progress
Follow each upload through queued, separating, preview, and ready states.
Private by default
Your files are encrypted in storage and temporary. Each job shows its access deadline; paid results remain available at least 24 hours after becoming ready, then automated cleanup removes expired objects. We never share or publish your uploads.
No software to install
Use the web app on a current phone, tablet, or desktop browser; cloud processing handles the separation.
Check the mix before you spend a credit
Use matched playback levels and the exact section you plan to edit, rehearse, or study.
What four stems reveal that a two-track split cannot
A vocal and instrumental pair is enough for simple karaoke, but four stems answer more useful questions. Solo drums to inspect groove and room sound, mute bass to hear harmonic space, compare vocals against the other bed, or rebuild only the section that needs work. This makes the same upload useful to a singer, drummer, bassist, producer, and teacher without creating separate jobs.
A practical quality check before paying
Choose the 30-second preview you want to inspect. Use it to check obvious bleed, missing consonants, unstable bass transients, and abruptly cut reverb before choosing a complete download. Free preview jobs do not use a credit; full-track jobs reserve one credit when processing starts and refund it automatically if processing fails.
Choosing the right export for the next step
Original output is fastest when you only need the model result. WAV is convenient for editing and broad DAW support, FLAC avoids another lossy encode while using less space than WAV, and MP3-320 is easier to move between devices. WAV and FLAC exports do not restore detail absent from the separated MP3 audio. Converted archives may take longer for long songs because every stem must be encoded before the ZIP is prepared.
Keep every comparison sample-aligned
When checking four stems, start each file from the same sample position and keep the original mix on a reference channel. Differences in start time, normalization, or limiter settings can sound like separation errors even when the predicted files are aligned. Compare one exposed section and one dense section at matched loudness before choosing an export.
Credits that do not expire
1 credit unlocks 4 stems plus drumless, bassless, and instrumental mixes. Previewing, listening, and failed processing jobs do not consume credits.

FAQ
Answers for free limits, formats, privacy, copyright, and download quality.
Is StemSlice free?
Yes. You can upload up to 3 songs a day and preview every stem free. Full-quality, watermark-free downloads use credits, which start at $4.9 and never expire.
What audio formats are supported?
Upload MP3, WAV, FLAC, M4A, AAC, or OGG. Download stems as WAV, FLAC, or 320kbps MP3.
How long does processing take?
Processing time varies with track length, source format, export choice, and queue load. The status stays available if your connection drops.
Is it legal to separate a copyrighted song?
Using a stem separator as a tool is legal. However, extracted stems remain the property of the original rights holders — you need their permission for commercial use or public release.
Do I need to create an account?
No. Anonymous users get the full free tier. An account is only needed to keep your credit balance and download history.
What happens to my files?
Source and free-preview files normally remain available for 24 hours after job creation. A paid full-track result remains available until at least 24 hours after it becomes ready. The page shows the exact access deadline; automated cleanup removes expired objects afterward.
How is this different from a vocal remover?
A vocal remover gives you two tracks (voice + instrumental). A stem separator gives you four or more, so you can remix, sample, or practice with far more control.
Extracted stems remain the property of the original rights holders. Commercial use requires their permission.
