AudioConf is a program developed for Linux systems that allows to make audio conferences over a local network. Its main features are the limited traffic of the network required for its operation and the ability to remove the audio stream of the client from the mixed audio stream received from the server, in this way it can be avoided the annoying problem of the echo.
AudioConf is composed by two parts the client and the server, the principal tasks done by the two parts are:
- SERVER The server receives the different audio streams from the clients, and after have mixed them together in a single stream resends the stream in broadcast/multicast to all the of the clients
- CLIENT The client sends the audio stream from the microphone to the server. At the same time it estimates the delay between the stream from the microphone and the stream from the server, and then eliminates its audio from the received stream. Finally the modified audio stream is played on the loudspeakers.
