Mic test
Before an online meeting or a stream, check that your microphone is picking up sound and that the level is right. You can also record yourself and play it back. Audio is processed in your browser and never sent anywhere.
Record and play back
Record yourself and play it back to check how your voice sounds to others. Recordings can be up to 30 seconds long.
Speaker check
Plays a short sound from the left, the right or both. Check that the left and right of your headphones or speakers are correct.
Settings
When you change a setting, the microphone is restarted to apply it. Depending on the browser and device, some processing cannot be turned off.
Microphone audio is processed in your browser and never sent anywhere. Recordings are saved to your device only when you press “Save”.
How to use
- 1
Press “Start microphone”
The browser asks for permission to use the microphone, so choose “Allow”. If you have more than one microphone, you can choose which one to use.

Speak and check the level
When you speak, the meter and the waveform move. If no sound is coming through, or the sound is quiet or clipping, the tool tells you.
- 3
Record and play it back
Press “Record”, speak, then press “Stop” to play back your recorded voice. Recordings can be up to 30 seconds long.
About the mic test
The sound level is shown in dBFS (a unit where the loudest sound that can be represented digitally is 0). This page says the sound is quiet when the loudest sound in the last 3 seconds is below −30 dBFS, and that it is clipping when it reaches close to 0 dBFS. When there is almost no sound for 3 seconds or more, it says that no sound is coming through.
“Echo cancellation”, “Noise suppression” and “Automatic gain control” are processing that the browser applies to audio for online meetings. They are on by default, so you can check under conditions close to most online meeting services. Turn them off to check the sound exactly as the microphone picks it up. Depending on the browser and device, some of this processing cannot be turned off.

Frequently asked questions
What should I do if the microphone does not respond?
First, check that the browser is allowed to use the microphone (you can change this from the icon to the left of the address bar). Next, check that the browser is allowed to use the microphone in Settings > Privacy & security > Microphone on Windows, or in System Settings > Privacy & Security > Microphone on macOS. If you have more than one microphone, choose the microphone again on this page.
Can I check how my voice sounds?
Yes. Press “Record”, speak, then press “Stop” to play back the recorded voice. Recordings can be up to 30 seconds long and are saved to your device only when you press “Save”. When you are using headphones, turn on “Listen to the microphone” to hear yourself while you speak.
Does it work on phones?
Yes. Use Safari on iPhone and iPad, or Chrome on Android. On phones you may not be able to choose a microphone; in that case the microphone chosen by the device is used.
Is my audio sent to a server?
No. The microphone audio is processed in your browser and never sent anywhere. Recordings are not stored on this site's server. This page does not send processing statistics either.
