Test your microphone. Hear what it captures.
Check whether your browser receives sound from your microphone. Watch the input meter, record a short sample, and listen back before your next call or recording.

How to test your microphone online
- 01 / ALLOW
Start and grant access
Connect your microphone and press Start microphone test. Allow access when your browser asks. Your browser or operating system selects the input device.
- 02 / SPEAK
Watch the input meter
Speak at a normal distance and volume. A moving meter indicates that the browser is receiving a signal. It cannot tell you whether the voice is clear or which microphone is active.
- 03 / LISTEN
Record and play back
Record the 10-second sample and listen through headphones or speakers at a low volume. Check words, distortion and room noise. Stop the microphone when finished.
Troubleshooting
What to do if your microphone test is quiet or silent
First check the physical mute switch and cable. In your device settings, select the intended input and confirm that the browser has microphone permission. If you have a headset and a built-in microphone, tap gently near each or speak at different distances to confirm which one is capturing sound.
If the meter moves but the recording sounds quiet, check both microphone input gain and your playback volume. Increase input gain gradually and listen for distortion on louder words. A meter reaching its maximum can indicate clipping, but a low meter reading alone does not establish that a recording will be clean. Read how microphone gain affects a recording.
Pause briefly before and after a sentence to hear room noise, then listen for clicks and overlapping sounds while speaking. Move closer to the microphone or reduce the noise at its source and record another sample. For an existing recording, the voice isolator is a separate upload-based service; this test does not remove noise or change your live call audio.
The browser may apply its own microphone processing. The meter displays relative digital peak level, not a calibrated sound-pressure reading, and the recording format depends on browser support. The sample is temporary; save your actual work in your recording application.
Find where the signal stops
Why is my microphone not working?
Compare the same microphone in your device settings and in this browser test. The result helps narrow down whether the problem is the input, permissions, or playback.
| What you see | What to check next |
|---|---|
| Neither the system nor browser detects sound | Check the physical mute switch, connection and selected input. For a wireless headset, confirm it is connected. Test another port or microphone if available. |
| The system sees sound, but the browser does not | Check microphone permission for your browser in the operating system and for this site in the browser. Restart the test after changing access or input settings. |
| The meter moves, but the sample is silent | Check the player and your selected speaker or headphones, then turn the output up gradually. Test another recording to distinguish a playback problem from a microphone problem. |
| The sample is quiet or distorted | Speak at your normal distance and adjust input gain gradually. Retest louder words and pauses. A moving meter cannot assess clarity or guarantee the correct device was selected. |
Test the microphone in Windows 11
Open Settings → System → Sound. Under Input, select the microphone and open its properties. Use Start test, speak, stop the test and play the recorded sample. If access is blocked, check Settings → Privacy & security → Microphone, including access for desktop apps. See Microsoft’s microphone troubleshooting steps.
Check microphone input on a Mac
Open System Settings → Sound → Input, select the intended microphone and speak while watching the input level. If the browser cannot use it, check System Settings → Privacy & Security → Microphone for browser access, and check the browser’s site permission. Apple explains sound input settings and microphone access. Menu names can vary by system version.
If the system test works but a particular calling application still cannot hear you, check its own microphone selection and mute controls. This browser test does not change settings in other applications. If you can hear the voice but it sounds dull, follow the muffled microphone troubleshooting guide.
A few useful answers
Online microphone test questions
How do I test my microphone online?
Start the test, allow microphone access, and speak at your normal level. The meter should move. Record a short sample and play it back to check intelligibility and noise.
Is my microphone audio uploaded?
This test reads your microphone in the browser and does not send the audio to Saturalabs. A playback sample is temporary and disappears when you leave or record again.
Why does the meter not move?
Check that the intended microphone is connected, unmuted and selected in your browser or operating system. Allow microphone access and try speaking closer to it. Other applications or device settings may affect availability.
Why can I see a signal but hear no playback?
Check speaker or headphone output, volume and the player controls. A moving meter confirms an input signal, not that playback is routed correctly. Some browsers do not support making a recording sample.
Does this test measure microphone quality or sound pressure?
No. The meter shows a relative digital input peak, not calibrated sound pressure or loudness. Listen to a sample for distortion, unwanted background sound and clarity.
