USB stick or a folder

Instrumental or guide vocal
Export the clean instrumental, or keep a quiet guide vocal for the songs nobody knows yet.
Themes and fonts, previewed live
Style the on-screen lyrics and watch the karaoke preview update before you commit.
Standard .mp3 + .cdg
The exact format CDG players, DJ rigs, and in-car karaoke systems already understand.

The problem

Still buying karaoke tracks one song at a time?

Most karaoke machines and CDG players still depend on MP3+G/CDG files. That usually means buying fixed-catalog tracks one at a time, hunting for compatible files, or dealing with old libraries that never have the songs people actually want to sing.

Beltr gives your existing karaoke setup a modern upgrade.

Export files for compatible karaoke hardware
Keep everything local on your computer

How it works

From song file to MP3+G in a few steps.

No catalog hunting. No web uploads. Just your music, your machine, and a clean MP3+G package.

1

Add a song

Import MP3, FLAC, WAV, or your existing karaoke files. Beltr handles the messy edges of legacy CDG libraries automatically.

2

Remove or lower vocals

Beltr uses local AI vocal separation (Demucs v4) to create a karaoke-ready mix on your computer — no cloud upload.

3

Sync the lyrics

Build a clean karaoke display with readable, timing-aware lyrics. Tweak by hand if a line needs a nudge.

4

Export MP3+G

Save a compatible MP3+G package — standard .mp3 + .cdg — for supported karaoke machines and CDG players.

Compatibility

Built for karaoke hardware owners.

Bridge modern AI vocal separation with the karaoke gear you already trust.

Karaoke machines

Create MP3+G files for compatible home karaoke systems.

CDG players

Keep legacy CDG workflows alive with modern AI processing.

DJ & KJ rigs

Build custom karaoke tracks for private events and party libraries.

In-car karaoke systems

Export files for systems that support MP3+G / CDG playback.

Existing CDG libraries

Bring your old MP3+G karaoke files into a modern desktop app and play them next to new AI tracks.

USB / disc workflows

Drop exported MP3+G onto a USB stick or burn it for hardware that expects disc-style karaoke files.

Guide-vocal mode

Export a clean instrumental, or a guide-vocal mix with the vocal on one channel and music on the other — for machines with a vocal-cancel switch.

Folder layouts

Write the USB stick the way your player browses: flat, a folder per song, or sorted by artist.

Compatibility depends on your player's supported file formats. Beltr exports MP3+G for systems that support MP3+G/CDG playback.

More than export

Burn the discs, or skip them entirely.

Export MP3+G for your hardware, or just sing straight from Beltr: cinematic lyrics on the TV, live pitch scoring, and a practice room for the songs you're still learning.

Cinematic lyrics on the TV
Word-by-word lyrics under a spotlight, your music video playing behind them.
Live pitch scoring
A pitch bar shows the note to hit, and the score climbs line by line.
A practice room
Slow any song down, loop the hard part, and drill it solo until it's yours.
Record & share the night
Beltr films your performance as you sing and drops a vertical clip on your phone, ready to post or text. Made on your machine, shared only when you tap.
