auXync

auXync turns your phone into a perfectly-synced second view of the live performance happening in front of you. In a large venue, the sound from the stage reaches every seat at a different time — and so does any video stream of that same performance. auXync solves both. The auXync server on the venue's machine streams live video over local Wi-Fi to every audience phone, and each phone individually delays that stream by the exact amount of time it takes the live sound to reach where you're sitting. The result: what you see on your phone stays locked to what you hear with your ears, no matter where you are in the room. KEY FEATURES • Live video from the venue, streamed over local Wi-Fi — no internet connection needed. • Per-listener audio synchronisation, calibrated from your distance to the stage using your device's location and the venue's published geofence. • Augmented Reality overlay mode — point your phone at the stage and watch the live stream composited over the real view, giving you a close-up of the performer wherever you sit. • Pinch-to-zoom and full-screen landscape viewing. • Tap to clap or send a heart — the performer's screen reacts to the audience live, so you can be part of the show even from the back rows. • Picture-in-Picture support — keep the stream running in a floating window while you use other apps. HOW IT WORKS 1. Walk into the venue and join the local Wi-Fi network the performance organiser has set up. 2. Open auXync. The app discovers the venue server automatically, or you can scan the QR code printed in the programme. 3. Allow location access when prompted — that's how the app knows your distance from the stage and how much audio delay to apply. Location is used only for synchronisation; it never leaves your device. 4. Sit back and watch. The stream stays in sync with the live sound throughout the performance. WHO IT'S FOR auXync is designed for ticketed live performances in venues that have set up an auXync server — concerts, recitals, theatre, dance, and large outdoor performances where the audience is too far from the stage to see clearly with the naked eye. The 30 May 2026 carillon recital at the National Carillon (Canberra, Australia) is the first public deployment. REQUIREMENTS • Android 10 (API 29) or new
