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
| Channels | Quality | Bandwidth (for buffer : 2.67ms) | Bandwidth (for buffer : 5.33ms) | Bandwidth (for buffer : 10.67ms) | Bandwidth (for buffer : 21.33ms) |
|---|---|---|---|---|---|
| Stereo | High | 894 Kbps | 657 Kbps | 541 Kbps | 483 Kbps |
| Stereo | Medium | 672 Kbps | 444 Kbps | 328 Kbps | 270 Kbps |
| Stereo | Low | 606 Kbps | 372 Kbps | 256 Kbps | 198 Kbps |
| Mono | High | 672 Kbps | 444 Kbps | 328 Kbps | 270 Kbps |
| Mono | Medium | 594 Kbps | 366 Kbps | 250 Kbps | 192 Kbps |
| Mono | Low | 534 Kbps | 306 Kbps | 190 Kbps | 132 Kbps |
Network bandwidth
There is one upstream (musician sending to the server) and one downstream (server sending back the mix to the musician) 
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.
