-52 timestamp units
RTP timestamp clock
8000 Hz

Expected results

Updated jitter
22 timestamp units
Updated jitter duration
0.00275 s

Load the example in the workspace to reproduce these results. Display rounding does not change the underlying calculation.

How to use this tool

  1. Enter the labeled inputs in the indicated units.
  2. Calculate and compare every output against the stated model assumptions.

Try this example

{
  "previous": 20,
  "difference": -52,
  "clock": 8000
}

Accuracy and scope

D is change in transit time expressed in RTP timestamp units; not raw packet-arrival spacing. Simplified analytical model; not a design recommendation or safety certification.
