Low-Latency Connection / client and server (http://llcon.sourceforge.net)
|

|

|
INTRODUCTION:
|
|
The llcon software enables musicians to play together over the internet. The
|
|
way it works is that there must be one server which collects the audio data
|
|
from each client, mixes all together and sends the mix back to each client.
|
|
The minimum internet connection speed at each client must be 256 kbps upstream
|
|
and 1 Mbit downstream. The server software must be located at a server with a
|
|
very fast internet connection (at least 1 Mbps for up- and downstream) and a
|
|
very low ping time. To get satisfactory results, the ping time from the client
|
|
computer to the server should not exceed 30 ms average and the network jitter
|
|
should be as low as 2-5 ms (To get a low ping time on DSL connections, an
|
|
extra option "DSL fast path" should be enabled by your internet provider).
|
|
|
|
The llcon software package includes both, the server and the client
|
|
functionality which can be selected by using command line arguments.
|
|
|
|
For starting server type ./llcon -s
|
|
|
|
For test purpose it is possible to run server and client on the same computer. For
|
|
this setup first start the server and then the client. Type in 127.0.0.1 for the
|
|
IP address in the client software.
