Start the test and allow microphone access when asked.
If input is visible, record a short clip to check clarity. Call apps can use different microphone settings.
Check the audio reaching your browser with a live level meter, waveform and optional recording. Audio from this test is processed locally; playback helps you notice noise or distortion.
How to use this tool
Start the test, allow microphone access and speak normally. Choose another input if a device selector appears. Record a short clip, stop recording and play it back. Stop the test when finished.
What this test can and cannot show
Microphone access requires browser support and permission. A moving meter confirms browser input, not the quality of a call app or a hardware diagnosis. Recording support and audio format vary. The playback is not automatically saved as a file.
Updated October 1, 2026. Browser and device support varies.
Questions and troubleshooting
Why is there no microphone input?
Check the site’s microphone permission and the operating system’s input setting. Speak after starting the test, then select another microphone if listed. A blocked permission or unavailable device can prevent the browser from receiving audio.
Is the level meter a decibel measurement?
No. The bar visualizes peak sample amplitude in the browser. It is not calibrated to sound pressure level and cannot compare microphone sensitivity across different gain settings. Listen to the short recording for a practical clarity check.
How this tool was checked
Automated Chromium checks on October 1, 2026 covered denied access, recording, playback and stopping tracks using simulated audio. They verified software behavior, not physical microphone quality.
