What does AI Vocal Separator do?
AI Vocal Separator splits a song you already made in Music Factory into parts you can use on their own. The standard split costs 20 credits and returns an isolated vocal and the instrumental behind it, with the original alongside them; a fuller split costs 30 credits and returns whatever further parts the separation produces for that track. There is nothing to upload — the run works from the job behind the song — and nothing is rewritten, because separation only divides what the recording already contains.

What the parts are good for
Perfect for Remixing
Use isolated stems to create remixes, mashups, and new arrangements from existing tracks.
Know more →What a split gives you back
One finished song goes in and separate audio files come out, cut from the same source and sharing the same timeline. Nothing is rewritten and nothing is added — the run only divides what the track already contains.
What the AI Vocal Separator Does, and Who Reaches for It
A finished song is a single mixed file — every voice, drum hit, bassline, and synth pad glued together into one waveform. The AI Vocal Separator un-glues it. Point it at a track you made in Music Factory and it returns two independent stems: an isolated vocal, stripped of the backing, and an instrumental with the singing removed. You get to treat the parts of a song as separate ingredients again, which is something a stereo mixdown normally makes impossible. It is deliberately narrow, and that focus is the point. The separator does not rewrite your song, change its arrangement, or add anything. It reads what is already there and pulls it apart along the line between voice and instrument, so the material you keep is the material you generated — nothing invented, nothing removed except the layer you asked it to isolate.

Once the split finishes, the useful step most people skip thinking about is how the stems behave once you drop them into an editor. Because both files are cut from the same source, they share an identical length and start point, so you can line them up on separate tracks at the same position and they stay in sync — no nudging, no time-stretching to make the vocal sit back on top of the instrumental. That shared timeline is what makes the pair easy to work with: mute the vocal for a karaoke pass, mute the instrumental to audition the acapella alone, or blend both back with the vocal a touch louder to rebalance a mix you were not happy with. In a video editor the instrumental stem does the quiet heavy lifting. Lay it under narration or dialogue and the words on screen stop competing with sung lyrics, which is usually why an edit felt cluttered in the first place. For a remix in a DAW, the isolated vocal drops onto its own track over a new tempo or key, and because it arrives as a standard audio file with no watermark or locked format, you treat it like any other clip — trim it, add reverb, chop it into phrases. The point is that separation is the setup, not the finish; the real work happens after the stems land, and they are built to slot into that work without extra conversion.
Try it now →Reading the Result and Working Around Its Limits
It helps to know what a separated stem can and cannot do before you commit a track to it. Separation divides what is present; it does not invent anything that was never there. So faint bleed at the edges of a stem — a ghost of the instrumental hiding under an isolated vocal, or a trace of the vocal in a busy instrumental — is a sign the source layered those elements tightly, not a fault to keep re-running the job to fix. When you spot it, the practical move is to lean on the arrangement: layer a fresh element over the thin spot in a remix, or keep the karaoke backing at a level where a residual whisper of vocal never surfaces. For anything you plan to build on heavily, audition the stems on headphones before you spend hours arranging around them. A quick listen tells you whether the vocal is clean enough to feature up front or better suited to sitting further back in a new mix. If the split falls short of what a project needs, the more reliable fix is usually upstream — generate or choose a source with a clearer, more forward vocal — rather than paying to separate the same difficult mix again and expecting a different outcome.
Try it now →Getting the Cleanest Stems: Tips That Actually Help
Separation quality is only ever as good as the source, so the biggest lever you have is the mix you feed in. A track where the vocal sits clearly forward — audible, not buried under wash and reverb — gives the AI an unambiguous line to follow, and the isolated vocal comes back with fewer artifacts clinging to it. Songs where the voice is drenched in effects or fighting a dense arrangement are simply harder to untangle, and that difficulty shows up as faint bleed at the edges of each stem. Finally, plan around the fact that separation is a read-only operation. It cannot repair a muddy mix or improve a vocal that was already weak in the original — it can only divide what exists. If you know you will want stems later, it pays to generate the source track with a clean, well-defined vocal in the first place, because a confident lead in the mixdown is what makes a confident split on the way back out.
Try it now →How to split a track into stems
Three steps in the browser, with the credit cost on the row before you commit.
Pick the track
The chooser lists songs already in your Music Factory library — a fresh generation, one you continued with Extend Track, or a track you had restyled. There is no upload step: the request carries the job behind the song, its task id and its audio id, rather than an audio file, which is why an mp3 from elsewhere cannot be the starting point.
Choose how far it splits
One setting on the card decides both the result and the price, and each row shows its own figure before you commit. The standard split is 20 credits and gives you the vocal and the instrumental — the pair most people want for a karaoke backing, an acapella or a remix starter. The fuller split is 30 credits and takes the track further apart, which is worth paying for only when you actually need the individual parts.
Run it and collect the parts
The job runs in the background rather than returning on the page, so you can close the tab. Each part lands in your library as its own audio file, playable and downloadable one at a time or together, with no watermark and nothing to convert before it goes into a session.
When taking a song apart earns its keep
Put the vocal over something else
The most common reason people separate a track is to remix it. Pull the vocal off a song you generated, drop it over a completely different tempo or genre bed, and you have a fresh arrangement that keeps the topline you liked. The instrumental stem is just as useful in the other direction — it becomes a clean instrumental version you can hand to a different singer, use under a voiceover, or license as a backing track without the original lead getting in the way.
Try it now →A karaoke version of your own song
Karaoke is the second big use, and it is where the separator pairs naturally with the rest of Music Factory. Take the instrumental stem as your backing track, then run the original song through Timestamped Lyrics to get synced words, and feed both into any lyric-scroll or karaoke player. The instrumental plays while the timestamps highlight each line right as the singer would hit it — that combination of a vocal-free bed plus synced text is the whole recipe for a karaoke version of something you generated yourself.

Frequently asked questions
How does AI Vocal Separation work?
Select a Music Factory track and the AI uses advanced audio processing to separate vocals from instrumentals. The result is two clean stems: an isolated vocal track and an instrumental-only track that you can use independently.
What quality can I expect from the separated stems?
The AI produces studio-quality separation with minimal artifacts. Vocals are cleanly isolated and instrumentals retain their full fidelity. Results are comparable to professional stem separation tools.
Can I use this for karaoke?
Yes. The instrumental stem makes a perfect karaoke backing track. Pair it with Timestamped Lyrics for a complete karaoke experience with synced lyrics display.
Why does vocal separation cost more than other features?
The standard split does not cost more: at 20 credits it is the same flat figure a song, an extension or a cover costs. Only the fuller split is dearer, at 30 credits, and it is the one control on the card — each row shows its own price before you commit, so the number on the button is always the number for the run you are about to make. The fuller split costs more because separating a mix further is genuinely more work upstream; what comes back from it is whatever parts the separation produces for that particular track, listed and downloadable one by one rather than a fixed set promised in advance.
Key takeaways
What it takes
A song already in your Music Factory library, and nothing else. There is no upload: the split runs on the job behind the track, so a recording from your own computer is not an input this tool accepts.
What it costs
20 credits for the standard vocal-and-instrumental split, 30 credits for the fuller one, spent when the run starts. The row you pick sets the number before you commit. No subscription is required.
Vocal split vs full stem split — what do you get for the credits?
| Option | Stems you get | Best for | Credits |
|---|---|---|---|
| Vocal separation | Vocal stem + instrumental stem | Karaoke backing, acapellas, remix starters | 20 credits |
| Full stem split | Every further part the separation returns for that track, each one on its own | Detailed remixing, sampling, production | 30 credits |
