Network Requirements

Audio bandwidth

The audio settings have an impact on the required network bandwidth. The below table summarizes the network requirements with respect to the configuration of:

  • channels : stereo/mono
  • quality : high/medium/low
  • audio buffer duration : 2.67ms, 5.33ms, 10.67ms, 21.33ms

With the following units

  • ms : milliseconds
  • Kbps : Kilo-bits per seconds (Reminder : 1Mbps = 1024Kbps, 1KByte = 8Kbits)
  • Mbps : Mega-bits per seconds

Network bandwidth

There is one upstream (musician sending to the server) and one downstream (server sending back the mix to the musician) image

Note also that mean ADSL2 transfer rate is 10 Mbits/second for downstream and 1 Mbit/second for upstream. The actual performance depends on distance to the provider, which may theoretically range from 24Mb/s at 0.3km to 1.5Mb/s at 5.2km for download rate.
