Speakers, not headphones · volume about halfway
Open this on your other device
A phone, a tablet or another computer. It opens in the browser, no app to download, the same way your audience joins a show.
Using a phone as speaker two? Point its camera at this code. Then tap Start Listening on that device too.Next to another phone? It can scan this.
It's one live show for everyone. Whenever and wherever a device joins, it lands on the same moment as every other device playing the demo, just like a real audience.
The sync switch
With both devices playing, knock this device out of sync and listen to what changes. Speaker two stays locked.
Start speaker one to use the switch.
The switch only delays this device's audio. Nobody else hears a difference, including other visitors on the demo.
What you're hearing
This is the same sync engine your audience gets. It's a live stream, not a recording.
Every device follows the same timeline
The demo runs as one live show. Whenever you join, you land at the same moment as every other device playing it, wherever it is.
Different paths, same moment
One device might be on Wi-Fi and the other on cellular. Each one corrects continuously for its own connection.
Scan, tap, listen
Speaker two joined from its browser, just like a spectator scanning a sign at a show. The PulseMesh app adds car-audio and Bluetooth delay compensation on top.
Try it with a room
There's no limit to two. Put the link on a screen, have everyone open it, and listen to a room full of phones play as one.
Now picture it at your show.
Lights, drones, fireworks or screens: the audio stays locked on every phone in your audience.
