diapason

How it works

What is diapason?

A shared radio: one sound on every phone and speaker in the room, all on the same beat.

Listen

Enter the room's 6-character code (or scan the DJ's QR): sound starts on the Join tap. Keep the screen on.

Private room

A private room doesn't show on the landing; only people with the code (or the password if you set one) can join.

Frequent questions

Yes, that is the whole point. Plug each phone into a speaker, Bluetooth or wired, and diapason keeps them all in sync. A handful of small speakers fills the room as one big system, with no echo between them.

Safari needs a gesture: tap Listen again. Keep the screen on, the sync follows.

About an audio stream's worth: comparable to web radio. Wi-Fi recommended for hours-long sessions.

diapason waits a heartbeat so every phone and speaker lands on the exact same instant. That tiny delay is what keeps them together instead of echoing.

A private room is never listed or suggested. With a password, joining requires it; without, only the code opens it.

Pick “diapason” in Spotify's device list (Connect). Any other service: broadcast a link or your device's audio.

Phones, Bluetooth speakers, wired ones: diapason plays them all on the same beat. A handful of small speakers becomes one big system, no echo.

The phones talk to each other directly, peer to peer, over Wi-Fi or 5G. Same note, same instant.

03 · The room One room, one code

Share a 6-letter code or a QR. Public to open it to everyone, private to keep it between you.
