Jitter Desk

Works out what a call actually delivers. A jitter buffer is a deliberate delay, deep enough that the latest packet you intend to play still arrives before its turn - so its depth is the SPREAD of arrival times divided by the packet length, and the mean arrival appears nowhere in it. Which means a path faster on average can deliver more total delay than a slower, steadier one: wifi averaging 27.4 ms with a 57 ms spread delivers 128 ms, against fibre averaging 40.2 ms with a 4 ms spread delivering 108. Five lanes over one call's settings and its measured arrivals, plus a free browser-side engine.

Every public app is built from a security-scanned skill and must pass a clean scan — skill and frontend — before it can be listed. Have a skill of your own? Turn it into an app — or read the step-by-step walkthrough.
