Step-by-step guide
Modern AI can split the singer from the music in a minute or two — right on your computer, no upload required. Here's exactly how, and how well it really works.
To remove vocals from a song, use AI vocal separation software. Install Beltr, add a song you own, and its on-device AI splits the lead vocal from the instrumental in a minute or two — nothing is uploaded. You can fully remove the vocal or just lower it, then sing along or export the instrumental. How clean it sounds depends on the song's mix.
Step by step
Download Beltr for Mac, Windows, or Linux. It runs the AI locally on your machine, so your song is never uploaded to a server — and it's a one-time purchase, not a subscription.
Drop in a music file you already have — MP3, FLAC, or WAV. Beltr works on your own library, so you're not limited to a fixed catalog.
Beltr's on-device AI (Demucs) splits the lead vocal from the instrumental in a minute or two. No internet connection needed once it's installed.
Use the stem slider to fully remove the vocal for a clean instrumental, or lower it to keep a soft guide vocal to sing against.
Sing along with synced lyrics on your TV, or export the instrumental to a file — including MP3+G for karaoke machines.
The honest part
AI separation is dramatically better than the old "cancel the center channel" tricks, and on well-recorded songs the instrumental can sound remarkably clean. But it isn't magic: results vary by song. Densely layered, heavily processed, or lo-fi tracks are harder to separate cleanly than a clear studio recording, and you may hear faint traces of the vocal. That's why Beltr lets you lower the vocal instead of removing it entirely — and why the 5-song free trial exists: test your actual songs before you buy, on your own machine, with nothing uploaded.
Why on your own computer
Most online vocal removers make you upload your file and pay every month. Beltr does it locally, once.
Because Beltr runs the AI on your device, your music never leaves your computer, there's no per-song limit, and it keeps working offline. And instead of removing vocals as a chore, Beltr turns it into a whole karaoke setup — synced lyrics on the TV, phones as remotes, live scoring. One payment of $19.99, yours forever.

FAQ
Use AI vocal separation software. Install Beltr, add a song you own, and its on-device AI splits the lead vocal from the instrumental in a minute or two. You can fully remove the vocal or just lower it, then sing along or export the instrumental.
AI can remove most of the lead vocal, and on many songs the result sounds clean. How complete it is depends on the song's mix and recording — some tracks separate better than others. You can also choose to lower the vocal instead of removing it entirely.
Neural-network AI separation (like Demucs) gives far better results than old left-right or center-channel cancellation tricks. Beltr runs this AI on your own computer, so it works on any song you own without uploading your audio.
Yes. Beltr processes everything on-device, so your audio never leaves your computer. Many online vocal removers require uploading your file to their servers; Beltr does not.
It works on virtually any song you own, though quality varies with the recording. Densely mixed or heavily processed tracks are harder to separate cleanly than well-recorded ones.
Beltr includes a free 5-song trial. After that it's a one-time $19.99 purchase — no subscription, and lifetime updates are included.
A tool we like
Plenty of people land on this page wanting to take a song apart rather than sing over it. If that's you, go and look at StemDeck. It is free and open source, it runs entirely on your own machine the way Beltr does, and it splits a track into up to six parts: vocals, drums, bass, guitar, piano and everything left over. Mac, Windows and Linux. A different job from ours, done properly.
Plain about why it is here: StemDeck keeps a short We Recommend list, on its repository and inside the app, and Beltr is on it, next to luthiers, pedal builders and a music shop. StemDeck takes no money from anyone on that list, ours included. That makes it a compliment with nothing attached, which is a rarer thing than a good review, and we would rather return it than sit on it. The app is free too, so the only thing that comes back to whoever built it is a star on the repository. If it saves you an afternoon, give it one.
Ready when you are
Install Beltr, drop in a track you own, and get a clean instrumental in a minute or two — on your own computer, nothing uploaded.
