How it works

One room. Two transports. Zero ceremony.

LOCRA is honest about platforms: iPhone rooms open as real-time rooms via WebRTC. Android with LE Audio can host broadcast-native rooms via Auracast. One room clock across both — never a fallback, always in phase.

  1. 01

    Open a room

    Pick a source — your library, your mic, your set. The room exists the moment you press open. Hosting requires Premium or above; guests join free.

  2. 02

    Nearby listeners walk in

    LE Audio broadcast & proximity awareness mean joining is as simple as arriving. Presence Rings show who is in the field.

  3. 03

    Remote listeners phase in

    One link. The LOCRA Clock holds everyone — across the room or across the country — to the same instant.

  4. 04

    The room corrects itself

    LOCRA Mesh measures every speaker's real hardware delay & aligns cheap Bluetooth speakers with studio monitors, so the room sounds like one instrument.
