No tool is perfect on every track
Results change dramatically depending on genre, mix density, and source quality. Pop with centered dry vocals works best; dense rock and 808-heavy mixes are harder.

Why most separators frustrate people
Every tool has tradeoffs. Knowing them upfront saves you from wasting time and money.
Artifacts are still normal
Warbling, bleed between stems, and thin-sounding vocals happen with every separator. Cleaner source files and simpler arrangements help the most.
Subscriptions and expiring credits add up
If you only need a few tracks per month, per-minute billing and monthly plans feel wasteful. Unmix keeps browser testing free with no credit system.
How it works
Three steps from file to separated stems. No account, no waiting.
1. Drop your file
Upload MP3, WAV, or a supported audio/video file. Everything runs locally in your browser — nothing is sent to a server.
2. Split into stems
Get vocals and accompaniment in seconds. On mobile, go further with 5-stem separation (vocals, drums, bass, piano, other).
3. Preview before you download
Listen to the hardest sections first. If the chorus sounds clean, the rest usually follows. Export only what you can actually use.
Browser (free) vs app
The free browser tool is for testing. The app is for full stem control.

What genres separate best
AI separation is not equally good on every kind of music. Here is a rough guide based on thousands of tracks.
Pop, R&B, singer-songwriter
Centered dry vocals with simple arrangements separate the cleanest. These are the best-case tracks for any tool.
Electronic, hip-hop, lo-fi
Results are mixed. Clean electronic tracks with distinct elements work well, but heavy 808 bass and sub-bass cause overlap with kick drums.
Dense rock, live recordings
The hardest category. Layered guitars, distortion, room ambience, and bleed make clean separation much harder for every tool on the market.
Who Unmix is for — and who it isn't
Unmix works best for specific users and use cases. Honesty saves you time.
Great fit
Occasional users who need 1–10 tracks separated per month. Musicians testing karaoke quality on a song before rehearsing. Producers scouting references before sampling. Students learning arrangement by ear. Teachers building lesson plans. Anyone who wants to hear separation quality on their own track before paying for anything.
Probably fine
DJs doing pre-extraction for live mashups. Podcasters cleaning up voice-plus-music clips. Film or video editors pulling clean dialogue out of music beds. Bassists, drummers, and pianists building practice tracks. Cover artists. Anyone who can tolerate minor artifacts because their workflow includes cleanup or loud monitoring.
You probably want something else
Professional mixing or mastering engineers needing pristine stems for paid releases — test a paid tool with higher-quality models. Anyone processing hundreds of tracks per month (the browser does one file at a time by design). Users on older mobile devices (mobile browser memory limits hit at 2–3 minute tracks). If any of these describes you, Unmix's mobile app or a competitor may fit better.

Tips for better results
Use the best source file you have
WAV and high-bitrate files separate cleaner than compressed MP3s. If your first result sounds rough, upgrading the source often fixes it.
Test the hardest section first
Skip to the chorus or the densest part of the track. If that sounds usable, the verses and bridges will too.
Compare tools on tough tracks
No single tool wins on every song. Advanced users often compare results from 2-3 separators and pick the best output per track.
FAQ
Can AI remove vocals perfectly from any song?
No. AI separation is useful but not flawless. Clean, centered vocals in simple mixes give the best results. Dense mixes, heavy reverb, and 808-heavy tracks will still have some artifacts.
Why do my vocals sound thin or hollow after extraction?
Thin vocals are the most common artifact in stem separation. It happens because the AI removes some harmonic content along with the instruments. Starting with higher-quality source files and less compressed masters helps.
What audio formats can I upload?
MP3, WAV, M4A, OGG, FLAC, and common video formats (MP4, WebM, MOV). WAV and FLAC give the cleanest results because they are lossless. For MP3, 320 kbps separates noticeably better than 128 kbps.
Which songs work best for stem separation?
Pop and R&B with centered, dry vocals and clean production separate best. Dense rock, live recordings, heavily compressed masters, and tracks with lots of reverb or effects are the hardest for every tool.
Do I need an account or subscription?
No. The browser tool is completely free with no signup, no credit system, and no expiration. You can test as many tracks as you want.
What is the difference between web and mobile?
The browser version splits into 2 stems (vocals and accompaniment) for quick testing. The iOS and Android apps offer full 5-stem separation into vocals, drums, bass, piano, and other.
How does Unmix compare to LALAL.AI and other paid tools?
Most paid tools use per-minute billing or monthly subscriptions with expiring credits. Unmix lets you test for free in the browser first so you can hear results on your own tracks before paying for anything.
Is it legal to separate stems from copyrighted songs?
It depends on how you use the output. Personal practice, learning, and private use are generally fine. Commercial use or public redistribution may require permission from the rights holder.
