Audio Latency Tester

Select your microphone and audio output device (headphones or speakers).
Place the output device close enough for the microphone to pick up the sound clearly.
Click Preview to monitor the live microphone level.
Adjust the detection threshold: drag the red thumb so the level bar stays below it during silence, but crosses it when a click sound is played.
Click Start . The tool plays random click sounds through the output device and records when the microphone detects each one.
Latency is calculated as the time difference between playback and detection, in milliseconds.
Click Stop when you are done. Review individual measurements and the average latency in the results section.

This tool reads audio from your microphone to measure playback latency. Allow access to list your devices and start testing.
