Is your microphone working properly? Use this free online Microphone Test to check your microphone before a video call, online meeting, interview, or recording session. Allow microphone access, speak into your mic, and watch the live sound-level meter respond to your voice. You can also select an available microphone and check whether your browser can detect it. No app installation is required.
Available devices may appear after you allow microphone access.
Tip: Speak normally or tap near (not directly on) your microphone. The meter should move when sound is detected. Keep your microphone volume at a comfortable level.
How to Test Your Microphone
- Open the Microphone Test tool on NexCalco.
- Click Start Microphone Test.
- Allow microphone access when your browser asks for permission.
- Speak normally into your microphone.
- Watch the live sound-level meter. It should respond when your microphone picks up sound.
- If you have multiple microphones, select another device from the dropdown to test it.
- Click Stop Test when you finish.
Understanding the Sound-Level Meter
The meter provides a visual indication of the sound entering your microphone. If the meter moves when you speak, the browser is receiving audio from the selected input.
The displayed percentage is a relative visual reading, not a calibrated volume measurement or a decibel reading.
What If Your Microphone Is Not Working?
If the meter does not respond, try these steps:
- Check that your microphone is connected properly.
- Confirm that the correct input device is selected.
- Allow microphone access in your browser settings.
- Check microphone permissions in your computer’s privacy settings.
- Make sure your microphone is not muted.
- Close other applications that may be using the microphone.
- Refresh the page and run the test again.
Is the Microphone Test Safe?
The tool processes microphone audio locally in your browser to display the sound-level meter. It does not intentionally record, save, or upload your voice. When you stop the test or leave the page, the tool stops its microphone tracks.
Your browser may still display its own microphone permission indicator while access is active.
Frequently Asked Questions
Is this Microphone Test free?

Why does the browser ask for microphone permission?
Browsers require permission before a website can access your microphone. Allow access to use the live sound-level meter.
Why is the meter not moving?
The microphone may be muted, the wrong input device may be selected, or the input level may be too low. Check your device and browser settings.
Can I test an external USB microphone?
Yes. Connect your USB microphone, allow browser access, and select it from the microphone dropdown if it appears.
Does this tool record my voice?
No. This tool only analyzes incoming audio to display a live sound-level meter. It does not provide audio recording or upload your voice.
