One audio file. One room. Everyone starts on the same millisecond.

  1. 1 Everyone opens this page and taps in. Same room, no code.
  2. 2 Anyone drops in the audio file. It downloads to every device.
  3. 3 Hit start. Three clicks count you in, then it plays — together.

Delay is measured and compensated automatically. You only need the slider if this device still sounds off — Bluetooth, a TV or a soundbar adds delay no browser can see.

With the clicks on everywhere, the room should sound like one click, not a flam. Drag right if this device is the one you hear late, left if you hear it early. Remembered here.
