Audio bandwidth
The audio settings have an impact on the required network bandwidth. The table below summarises network requirements with respect to the configuration of:
- Channels : stereo/mono
- Quality : max/high/medium/low
- Audio buffer duration : 2.67 ms (64 samples), 5.33 ms (128 samples), 10.67 ms (256 samples)
With the following units
- ms : milliseconds
- Kbit/s : Kilo-bits per second (Reminder : 1 Mbit/s = 1024 Kbit/s, 1 KByte/s = 8 Kbit/s)
- Mbit/s : Mega-bits per second
| Channels | Quality | Bandwidth (for buffer : 2.67 ms) | Bandwidth (for buffer : 5.33 ms) | Bandwidth (for buffer : 10.67 ms) |
|---|---|---|---|---|
| Stereo | Max | 2004 Kbit/s | 1770 Kbit/s | 1654 Kbit/s |
| Stereo | High | 906 Kbit/s | 729 Kbit/s | 613 Kbit/s |
| Stereo | Medium | 678 Kbit/s | 447 Kbit/s | 331 Kbit/s |
| Stereo | Low | 612 Kbit/s | 375 Kbit/s | 259 Kbit/s |
| Mono | Max | 1236 Kbit/s | 1002 Kbit/s | 886 Kbit/s |
| Mono | High | 684 Kbit/s | 480 Kbit/s | 364 Kbit/s |
| Mono | Medium | 600 Kbit/s | 369 Kbit/s | 253 Kbit/s |
| Mono | Low | 540 Kbit/s | 309 Kbit/s | 193 Kbit/s |
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 Mbit/s for downstream and 1 Mbit/s for upstream. The actual performance depends on distance to the provider, which may theoretically range from 24 Mbit/s at 0.3 km to 1.5 Mbit/s at 5.2 km for download rate.
