Audio Delay Test is for people checking whether Bluetooth headphones, speakers, or a TV make sound arrive out of sync with the picture. In a browser, you can match a beep to a flash with the sync slider and read an estimated delay in milliseconds, or use a tap test for a second estimate. Loop mode repeats the flash and beep on screen, which can help you judge sync on a TV or record it in slow motion. Compare different audio connections or playback devices to help troubleshoot lag and decide whether to adjust an AV sync setting. The tests on this page do not use your microphone, require an account, or upload test data. Results are estimates of the full playback chain—not laboratory measurements—and can vary with your screen, browser, device, and perception.
