Measure Audio Latency — Test Microphone Delay in Milliseconds

Audio Latency Test measures the delay between when your system plays a sound and when your microphone captures it — your round-trip latency in milliseconds (ms). Click Start Test, keep the room quiet, and you'll get a reading in seconds. Anything under 20ms is good for real-time use; above 150ms and you'll feel the lag during calls or live recording.

Click "Start Test" to measure your audio latency. Use headphones for accurate results.
