Stream Audio to Smartphones — In Sync with Your Video Screens
Your video is playing silently on a public screen — in a museum, a shop window, an event, or a city square.
A passerby scans a QR code. Instantly, they hear the soundtrack of your video — in their own language, on their own phone, perfectly synced.
Nubart SYNC makes this seamless experience possible.
No app to install. No WiFi broadcast. No beacons. No special hardware. Just a browser and a connection.
Our patented solution streams multilingual audio to any number of smartphones, in perfect sync with any on-site video. Looping, long durations, or large screens? No problem.
Use Nubart SYNC for digital signage, video walls, outdoor projections, laser shows — anywhere you want your screen to speak clearly and accessibly.

Why choose Nubart SYNC?
Unlock Audio for Public Video Displays — Without Hardware or Apps
Public spaces are full of muted screens — digital signage, ads in shop windows, safety instructions at airports, documentaries in waiting rooms. But sound is often forbidden due to noise regulations or social etiquette.
Nubart SYNC solves this with a clean, user-friendly solution: stream audio directly to smartphones via QR code. Visitors scan, select their language, and listen — all in perfect sync with the video.
No special hardware. No Bluetooth, beacons, or apps. Just the video, a QR code, and our cloud-based synchronization technology.
You can embed the QR code on the screen itself, or place it nearby. It works equally well in both indoor and outdoor environments — even with large screens, mosaics, or projection mappings.

How Is Audio Paired with Video Today?
And why Nubart SYNC changes everything.
The Old Way
Most current solutions require complex hardware: dedicated media players, RF/IR systems, RFID triggers, or iBeacons.
Some offer Wi-Fi broadcast — but only through captive portals, unreliable connections, or custom apps.
It’s expensive, high-maintenance, and rarely user-friendly.
The Nubart SYNC Way
Just a QR code. A smartphone. And perfect sync.
Nubart SYNC delivers multilingual, lip-synced audio straight to browsers — no app, no login, no friction.
It works instantly on any smartphone with internet access. Fully scalable. Shockingly simple.
What This Means for You
Lower costs. Zero hardware hassle. Maximum accessibility and reach.
Nubart SYNC is a patented SaaS innovation — now available in Europe, Australia, and soon the U.S.
It’s redefining what’s possible in digital signage, DooH, accessibility, and public engagement.
