A/V Test

Select a camera and microphone. Quick checks report numeric metrics automatically. Watches keep metrics here for Save metrics; audio and video never upload.

Keep this page visible and the computer awake. One capture session, no recording or upload. Save metrics before closing the page. Gaps and silence alone do not prove audio loss.

Stopped

Reporting starts with the test.

Not recording

No observations.

Audio/video sync and end-to-end delay: not measured by this check. Video callback gaps can include browser scheduling. Silence is not proof of audio loss. A separate paired-signal measurement is needed to verify synchronization.
