Jamulus is open source (GPL) networked music performance software that enables live rehearsing, jamming and performing with musicians located anywhere on the internet. Jamulus is written by Volker Fischer and contributors using C++. The Software is based on the Qt framework and uses the OPUS audio codec. It was known as "llcon" until 2013.
Jamulus is client-server based; each client transmits its own compressed audio to a server on the internet. The server mixes the (decompressed) audio stream for each user separately and re-transmits the individual compressed mix to each client. Each client has its own mixing console which controls its mix on the server.
Servers can be either public or private (termed "Registered" and "Unregistered", since Jamulus has no built-in user authentication mechanism), the former being listed by "directories" from which users can choose a server with the lowest latency for them.
