In many workflow and review articles, I have discussed the benefits of “latency-free” monitoring when it comes to audio latency, so that the human operator/host can perceive no noticeable delay when monitoring her/himself for QC (quality control) and/or to hear other participants too. Most of the audio interfaces and some of the USB mics I have reviewed have …

For measuring precise milliseconds I don’t have any suggestions, but if you search on YouTube for “audio video sync”, there’s a ton of videos of test signals. Generally with a circle with a sweep hand that hits the top every second or so, and when it does theres’s a very brief flash and very short beep at the same time.

Turn off your rear and side speakers then play a video program with lots of dialogue and minimal music or sound effects. You’ll hear the latency in the form of an echo (or more correctly a reverberation) between the two audio sources. Adjust the delay setting on your AV receiver or outboard delay unit until the echo goes away.
