Network Requirements

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 |
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.
