Testing guide
How to test your microphone online
This microphone test uses the Web Audio API to capture your mic input directly in the browser, measure the input level in real time, display a live waveform, and record a short clip you can play back immediately. Nothing is uploaded or sent anywhere.
Best for
- Checking whether your microphone is working before a video call, interview, or recording session.
- Comparing input levels and audio quality across different microphones or headsets.
- Diagnosing a mic that appears connected but produces no sound, low volume, or excessive noise.
How to run the test
- 1Click Allow Microphone Access and accept the browser permission prompt.
- 2Speak at your normal volume and confirm the level meter responds and the waveform moves.
- 3If you have multiple microphones, use the device dropdown to switch between them and compare.
- 4Click Record Clip to capture a few seconds, then Play Recording to hear yourself back.
How to read the result
A level meter that responds immediately to your voice means the mic is working and the browser can access it.
A flat waveform and zero level usually means the wrong input device is selected, the mic is muted, or permission was not granted.
If playback sounds clear at a comfortable volume, the mic, audio driver, and browser audio pipeline are all functioning correctly.

Frequently asked questions
How do I test my microphone online?
Open this page, click Allow Microphone Access, and speak. If the level meter moves and the waveform shows activity, your microphone is working. Record a short clip and play it back to confirm the audio quality sounds right.
Why is the level meter not moving?
The most common causes are: the wrong input device is selected in the dropdown, the microphone is physically muted, the system volume for the mic is turned down, or the browser did not receive permission. Check each of those in order.
Is my audio uploaded anywhere?
No. All processing happens locally in your browser using the Web Audio API and MediaRecorder API. No audio data leaves your device at any point, and recorded clips exist only in browser memory until you close the page.
Why does the browser say permission was denied?
Browsers remember previous permission decisions. If you denied microphone access before, you need to reset the permission in your browser site settings. In Chrome, click the lock icon in the address bar, find Microphone, and set it to Allow.
Can I test a specific microphone if I have several?
Yes. After granting permission, a device dropdown appears if your system has more than one audio input. Select the device you want to test and the tool switches to it immediately.
What does the peak level indicator show?
The peak marker shows the highest input level reached recently. It holds briefly so you can see the loudest point, then slowly decays back down. It helps you spot whether your mic clips at loud volumes.
