Audio Latency Tester
Measure the timing you can actually defend.
Generate a flash-and-click sync pattern, record the target, and inspect audio/video offset with event-level evidence, drift, jitter, confidence, and uncertainty.

Timing is not one universal number.
Encoded media timing, camera-observed playback, channel delay, and acoustic return each have a different reference clock. The app keeps them separate and includes the sign convention in every report.
Exact patterns
Use rational frame rates from 23.976 through 60 fps and sample-indexed audio events with a ground-truth manifest.
Inspect the evidence
Review event pairs, dropped or duplicated events, drift, jitter, confidence, and a 95% uncertainty range.
