Setting session parameters - Buffer

This article is part of the Source-Connect Pro and Pro X 3.9 User Guide

The higher the buffer value, the higher the possibility of avoiding audible packet loss. On the other hand, a higher buffer value means a longer communication delay. If you are on a T1 or higher connection (both remote plug-ins) you may find that reducing the buffer size offers lower delay with the same quality experience. If you or your remote connection are on cable or DSL, a higher buffer is recommended.

A value of at least 200ms is recommended, as values lower than this disable additional recovery algorithms designed to avoid packet loss. 

Additionally, the ideal setting for our recovery algorithms to work is to set the buffer to at least double the ping time between you and your connected user. If your latency increases too much you can set a higher buffer on the side of the connection that needs to receive the highest quality stream.
