  1. Start the test. Click Start test (or the big microphone button) and choose Allow when your browser asks to use the microphone.

  2. Pick your mic. If you have more than one — laptop mic, headset, USB mic or AirPods — choose the one you want to check from the menu at the top right.
  3. Make some noise. Talk, clap or tap the mic. If the waveform moves, the level meter lights up and the status turns green with Microphone is working, your microphone works.

  4. Record and listen back. Press Record, say a few words, press it again to stop, then play the clip to hear exactly how you sound on calls. Use the download button to keep it.

  5. Fine-tune. Switch echo cancellation, noise suppression and auto gain on or off to compare the sound, or put on headphones and use Hear yourself for live monitoring. The details panel shows the microphone’s name, sample rate and channels.

What the numbers mean

  • Input level is measured in decibels, where 0 dB is the loudest signal possible. Normal speech usually sits between −35 and −15 dB.
  • Peak is the loudest moment so far. If it reaches 0 dB the mic is clipping and will sound distorted, so lower its input volume.
  • Frequency is the strongest pitch the mic picks up, shown with its nearest musical note.

Microphone not working? Fix it step by step

  1. Read the message on the test. If the status turns red and says Microphone access blocked, your browser or computer is stopping websites from using the mic. If it says Microphone is busy, another app is using it (go to step 5).

  2. Allow the microphone in your browser. Click the icon to the left of the address bar, open Site settings (or Permissions) and set Microphone to Allow. Then reload this page and press Start test again.

    Chrome and Edge site settings. In Firefox and Safari, click the microphone icon in the address bar instead.
  3. Allow apps to use the microphone in your system. Windows 11/10: Settings › Privacy & security › Microphone — turn on Microphone access and Let desktop apps access your microphone. Mac: System Settings › Privacy & Security › Microphone — turn on your browser, then quit and reopen it.
  4. Check the mute switch. Many headsets have a mute button or a flip-up boom, cable remotes have a slider, and many laptops have a mic-mute key (often F4 or F8 with an icon of a crossed-out microphone).
  5. Close apps that may be holding the mic, such as Zoom, Teams, Discord, Skype or OBS, then press Start test again.
  6. Choose the right input. Pick your microphone in the menu above the visualizer, and in your system sound settings — Windows: Settings › System › Sound › Input; Mac: System Settings › Sound › Input.
  7. Reconnect the microphone. Unplug USB mics and try another port; for Bluetooth headsets, turn Bluetooth off and on or pair them again. Then reload this page.

Mic too quiet, too loud or noisy?

  • Too quiet: move closer (a hand’s width for headsets, 10–20 cm for desk mics) and raise the input volume in your system sound settings. Turn on Auto gain control for calls.
  • Distorted: if the peak hits 0 dB, lower the input volume or the gain knob on your mic or audio interface.
  • Background noise: turn on Noise suppression, move away from fans and keyboards, and use a directional mic pointed at your mouth.
  • Echo on calls: wear headphones or turn on Echo cancellation so your speakers don’t feed back into the mic.

About this microphone test

This free online mic test runs entirely in your browser using the Web Audio API. Your voice is analysed on your own device — nothing is uploaded, stored or sent to a server, and recordings disappear when you close the tab.

It works with built-in laptop and phone microphones, USB and XLR mics through an audio interface, gaming headsets, AirPods and other Bluetooth earbuds. Use it on Windows, macOS, Linux, ChromeOS, Android or iOS in any modern browser, including Chrome, Edge, Firefox and Safari. Run it before a Zoom, Teams, Google Meet or Discord call to make sure everyone can hear you.

Frequently asked questions

How do I know if my microphone is working?

Start the test and speak. If the waveform moves and the input level meter rises when you talk, your microphone works. Record a short clip and play it back to check the sound quality as well.

Why does the mic test show no sound?

The microphone may be muted, blocked in your browser or system privacy settings, or the wrong input may be selected. Check the mute switch, allow microphone access, close apps such as Zoom or Discord that may be using it, and pick another microphone from the list.

Is this mic test safe and private?

Yes. Everything runs locally in your browser. Your audio is never uploaded or stored, and recordings exist only in your open tab until you download them or close the page.

Can I hear myself through my microphone?

Yes. Put on headphones, start the test and click Hear yourself to monitor your microphone live. Use headphones to avoid feedback from your speakers.

What is a good microphone level?

For speech, aim for the level meter to stay mostly in the green, around −35 to −15 dB, with peaks below −6 dB. If the peak reaches 0 dB, the sound is clipping and you should lower the input volume.
