Before your first connection from a native client (i.e., not the Web), you should run the audio wizard to ensure your voice is transmitted loud and clear to other participants.

The connection dialog allows you to add a server: the server address is, using the default port (64738). It is recommend that you choose a username matching your handle here, and that you label the server so you can find it easily in your favorites.

Alternative: connect via the WWW

Although a native client will provide a better audio experience, you might not be able or willing to install an application. In this case there’s a web-based client that you can use with a modern Web browser. It may or may not work depending on your client, e.g., I could make it work with Chromium, but Firefox failed to detect my microphone. As they say, YMMV.

If you’re willing to use the Web instead of a native client, please point your browser to

If you use Matrix, and especially the Riot Web client, you may join the matrix channel on and connect from there.

Expected Behavior

This service is provided as a gift to the community.
You’re expected to behave with utmost respect to other participants at all times.
A rule of thumb is to be excellent to each other.

In general, as with other audio conferencing systems, please use a headset to avoid feedback loops.

Configuration / Setup

Please spend some time to test and setup your audio before the meeting as to avoid wasting other people’s time. The audio wizard may be difficult to get at first: ensure you’re testing your audio in the same conditions you will be participating to the conference (headphones + microphone, ambient sound) and push your mic volume to the max before it creates audio feedback loop for yourself (you can lower it after the audio wizard has completed to obtain best results.)

Push to Talk (PTT) / Mute

The default configuration for PTT mode is to simulaneously press the Control and Shift keys. Starting with client version 1.3.0, the default mode is voice amplitude, so your microphone won’t be muted, and you might be catching other participants’ voice, creating larsen: if this happens when you do not talk, please mute yourself by pressing the microphone icon (:studio_microphone:).


In general you would use the main room unless you have reasons not to (e.g., you’re on a radio show or a private channel in the THX or PUBLIC parts…)

Welcome, and enjoy your stay!

J’ai comme l’impression que je ne comprends pas le principe… je ne vois pas depuis ma connection web ( comment entrer dans une connection web-audio? J’ai l’impression que mon micro est ouvert mais j’ai l’impression qu’on ne m’entend pas…

Apparemment c’est réglé :wink: (nous sommes en conversation !)
