Use this test to measure your headphone audio latency directly in your browser.
It plays a short sound several times, records the playback through your microphone, and calculates the exact delay
between sound output and microphone input.
You’ll see your total round-trip delay in milliseconds — the time it takes for sound to travel from your computer to your headphones and back through the mic.
Play a short sound
The app plays a short, sharp click several times to use as precise timing markers.
Delay in your system
Small delays occur due to Bluetooth transmission, audio buffering, and headphone signal processing.
Headphones playback
Your headphones output the sound. Keep the volume comfortable and stable.
Microphone capture
The microphone records the clicks as played by the headphones. The app uses this to detect timing differences.
Processing and result
The waveform is analyzed locally to find matching peaks and calculate the average audio latency in milliseconds.
Your final result shows the total audio round-trip latency, which includes:
Typical ranges:
1. Keep the room quiet
Avoid fans or background noise — they can hide the test sound.
2. Position the microphone close to one earcup
Hold the earcup 2–5 cm from the mic so the clicks are clearly heard.
3. Adjust your volume
If the signal is too quiet, it won’t be detected.
If it’s too loud, it may clip and distort the result.
4. Don’t move devices during the test
Switching audio devices or moving the mic may affect timing.
5. Repeat the test
Run the test two or three times and take the average for best accuracy.
All sound analysis happens locally in your browser.
No recordings are uploaded, stored, or shared. The waveform data is processed in memory only.
Average Latency:
182 ms
(± 10 ms across 5 samples)
A smaller value means faster sound response.
A delay above 150 ms is often noticeable in videos, calls, and rhythm games.
Audio latency affects every sound interaction — from watching videos to playing games or recording music.
By measuring your actual delay, you can see how your setup performs and take steps to reduce lag for smoother, more
synchronized sound.
