Jamulus enables musicians to perform in real-time together over the internet. A Jamulus server collects the incoming audio data from each Jamulus client, mixes that data and then sends that mix back to each client. Jamulus can support large numbers of clients with minimal latency and modest bandwidth requirements.
Jamulus is free and open source software (FOSS) licensed under the GPL and runs under Windows (ASIO), MacOS (Core Audio) and Linux (Jack). It is based on the Qt framework and uses the OPUS audio codec.
Please see the Getting Started page containing instructions for installing and using Jamulus for your platform.
Official documentation for Jamulus is on the Jamulus homepage
