RoomCast user manual

This guide is for the person running the event. RoomCast sends sound from a Mac to phones in the same room over local Wi-Fi. People scan a QR code and listen in their phone's browser. They do not need to sign in or create an account. The audio stays on the local network. It is not uploaded to the internet, and the app does not record.

Download RoomCast for Mac Share with your venue Stuck on a step? Tell me

The current download from roomcast.channel is version 1.0.2 (build 2). About 50 phones on a modern Wi-Fi router can listen at once. The real number depends on the router, other traffic on the network, distance and walls, and the quality setting. The delay is usually around half a second, even on busy Wi-Fi.

Getting startedInstall RoomCast, learn the main window, test at home, and run the event.
