Video call diagnostic
Video call jitter test
Test whether unstable latency could make video calls sound robotic, freeze briefly, or feel delayed. This lightweight check sends small timing requests between your browser and BottleneckRadar and looks for jitter and lag spikes.
Call stability test
Ping, jitter, and lag spikes
Ready to check connection timing for video calls.
This test uses tiny same-origin requests, not a real Zoom, Teams, or Meet media stream. For download, upload, and latency under load, use the full bandwidth bottleneck test.
What this test measures
Video calls need consistent packet timing. A connection can have good download speed but still perform badly when latency jumps from one moment to the next. This test reports median latency, jitter, worst spike, failed samples, and a call stability score.
How to read the result
- Low jitter usually means audio and video timing should stay stable.
- High jitter can cause robotic audio, frozen video, and delayed responses.
- Large spikes can point to Wi-Fi interference, VPN routing, or router queueing.
- If calls get worse while someone downloads or uploads, run the full bandwidth bottleneck test.
A strong result here does not guarantee every call provider will be perfect. Meeting apps use their own servers, codecs, and routing. This page is best used as a quick browser-side stability check.
