The Jamulus software enables musicians to perform real-time jam sessions over the internet.
There is one server running the Jamulus server software which collects the audio data from
each Jamulus client, mixes the audio data and sends the mix back to each client.

It is based on the [Qt framework ](https://www.qt.io ) and uses the [OPUS ](http://www.opus-codec.org ) audio codec.

Required Hardware Setup
-----------------------
2019-06-15 18:26:13 +02:00
The required minimum internet connection speed is 200 kbps for the up- and downstream.
The ping time (i.e. round trip delay) from your computer to the server should not exceed 40 ms average.

For the Jamulus software to run stable it is recommended to use a PC with at least 1.5 GHz CPU frequency.
On a Windows operating system it is recommended to use a sound card with a native ASIO driver.
This ensures to get the lowest possible latencies.

**Windows users**: The Jamulus client software requires an ASIO sound card driver to be available in the system. If your sound card does not have native ASIO support, you can try out [this alternative ](http://www.asio4all.org/ )
