Pair your audio with on site videos using Nubart Sync

Internet-based AV sync tech

Would you like your public videos to " speak " without disturbing anyone? In the language of your audience's choice? And always with perfect lip-sync?

With Nubart Sync you just found the audio-video-synchronisation you were looking for.

Our patent pending solution is also simple and affordable. It does not require special equipment or complex technical systems such as broadcast, closed local networks, beacons or infrared. All you and your audience need is a regular internet connection (WIFI or mobile data). No app download nor registration are required.

Your listeners simply scan a QR code to get the soundtrack for your videos in the language of their choice. The sound will be streamed to them in perfect sync, with no discernible latency.

Nubart sync is fully scalable: suitable for any number of listeners. Looping is possible. Video length is irrelevant. Also suitable for mosaic video walls.
