Free AI Stem Separator

One song in, four stems out — vocals, drums, bass, and other instruments. Processing quality varies by mix, so every track can be previewed before download.

Let the AI separate

Secure cloud processing separates the mix into vocals, drums, bass, and other stems while the page shows the current stage.

3

Preview each stem

Solo any track for 30 seconds, free. Download full stems whenever you're ready.

Hear the separation wall

These licensed source recordings were AI-separated by StemSlice and excerpted to 30 seconds. User uploads are private and never published.

Inspect the arrangement one stem at a time

Keep every file sample-aligned while comparing vocals, rhythm, low end, and instrumentation.

Preview the opening excerpt

The four-stem model handles each recording differently, so use the free opening 30-second excerpt to check the source before downloading.

Model-predicted stems

The AI estimates vocals, drums, bass, and other from the full mix instead of relying on a simple center-channel or EQ filter.

DAW-ready output

Download WAV or FLAC and drag the stems straight into Ableton, FL Studio, Logic, or Pro Tools.

Your files stay yours

Encrypted storage, set to expire 24 hours after job creation and then removed by automated cleanup, never shared or published.

Prepare four stems for a real session

Source quality, alignment, export format, and rights all affect whether a split is useful.

Use a separator to study arrangement, not only remove vocals

Mute one stem at a time and note what changes at verse, pre-chorus, chorus, and bridge transitions. Drums reveal energy, bass shows harmonic movement, vocals expose doubles and stacks, and the other stem carries guitars, keys, strings, and effects. That view is especially useful when recreating an arrangement or teaching why a finished mix feels dense.

Sources that produce the cleanest stem boundaries

Lossless studio masters and high-bitrate releases usually separate more cleanly than phone recordings, live bootlegs, clipped files, or tracks with heavy crowd noise. Reverb and stereo widening can legitimately appear in more than one predicted stem. Treat a preview as evidence for this exact source rather than assuming every song by the same artist will behave identically.

Free preview and full export serve different jobs

The free path is for checking whether the split is useful and hearing each predicted part. A full export is for DAW editing, practice libraries, detailed transcription, or other work that needs the complete duration and chosen format. This distinction keeps evaluation accessible while reserving storage and conversion-heavy downloads for projects that will use them.

Preserve the original start time for recombination

Do not trim silence from individual stems before arranging them. Shared start time is what lets vocals, drums, bass, and other recombine against the reference without drift. Make creative cuts only after the files are aligned in the session, and keep one untouched copy of each export for troubleshooting.

Credits that do not expire

1 credit unlocks one full 4-stem download. Previewing, listening, and failed processing jobs do not consume credits.

FAQ

Answers for free limits, formats, privacy, copyright, and download quality.

What is a stem separator?

It's a tool that splits a finished song back into its individual tracks — vocals, drums, bass, and other instruments — so each can be used on its own.

Is this stem separator really free?

Uploading and previewing are free (3 songs a day). Downloading full, high-quality stems uses credits — from $4.9 for 5 songs, and credits never expire.

How many stems do I get?

Four: vocals, drums, bass, and a combined "other" track for everything else.

Will it work on live recordings or lo-fi tracks?

It works best on studio recordings. Live and very low-bitrate sources separate with more artifacts.

What formats can I download?

Lossless WAV, FLAC, or 320kbps MP3.

Is it legal to separate stems from a song I don't own?

The tool itself is legal, but the stems still belong to the rights holder. Get permission before releasing anything commercially.

Stem separator vs. stem splitter — what's the difference?

Just two names for the same thing. Both describe splitting a song into its component tracks.
