Hi,

Jitter is the DEVIATION of the expected timestamp. You want those to be
low, actually zero. When that's not the case software has to compensate
for that. If the jitter becomes to high speech degradation may follow.
All is depending of the robustness of the jitter buffer implementation.

Thanx,
Jaap
