# Jamulus - Internet Jam Session Software

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**](https://www.gnu.org/philosophy/free-sw.en.html) (FOSS) licensed under the [GPL](https://www.gnu.org/licenses/old-licenses/gpl-2.0.html)
and runs under **Windows** ([ASIO](https://www.steinberg.net) or [JACK](https://jackaudio.org)),
**MacOS** ([Core Audio](https://developer.apple.com/documentation/coreaudio)) and
**Linux** ([JACK](https://jackaudio.org)).
It is based on the [Qt framework](https://www.qt.io) and uses the [OPUS](https://www.opus-codec.org/) audio codec.
