Introduction

Multi-user voice conferencing allows a few users to chat with each other simultaneously. This helps organize online voice conferences, chat rooms, etc.

Server setup

Specify a protocol, port and sampling rate. Press the Start/Stop buttons to activate/deactivate the server.

Client setup

You can use our simple voice chat application as a Conference Server client. Make sure that you specify the same protocol, port and sampling rate as you have on the server side. Press the Connect/Disconnect button to start your chat session.

Programming background

This demo contains the ConferenceServer component which does most of work for you. All you have to do is set networking properties: Proto and Port; and audio properties: FormatTag (codec) and Pcm... (quality).

Use ConferenceServer.Active = True/False to activate/deactivate your server.
