Microphone Test

Check your microphone with a live level meter and a quick playback recording.

Turn on your microphone to watch the input level, then record 5 seconds and play it back.

Sound is never sent to or stored on a server; it is handled only in this browser.
What is the microphone test?

A tool that checks whether your computer, laptop or headset microphone picks up sound, using a live level meter and waveform, and lets you record 5 seconds to hear the real quality. Handy before video calls or recording.

How to use it

Press Start microphone test and allow microphone access in your browser. The bar and waveform move as you speak, and with several microphones you can choose one under Input device. Record 5 s and play back plays the recording right after it ends. Press Stop to turn the microphone off when done.

Note: The value (dBFS) is the digital input level and is not the same as real-world noise (dB).
Real-world uses

Check the microphone turns on before a video meeting or online class, compare headsets, or see whether the input volume is so low or high that the sound distorts.

FAQ

I denied microphone permission and it will not ask again.
The browser remembers a denial. Click the lock (or settings) icon left of the address bar, set this site's microphone to Allow, reload the page and start again. The same symptom appears if microphone access for the browser is switched off in your operating system's privacy settings.
The level bar does not move at all.
First check that the microphone you want is selected in the input device list. If it still does not move, make sure the operating system input volume is not zero or muted and that a headset's mute switch is off. Another app holding the microphone exclusively can also block the sound.
Is the recording saved or sent anywhere?
No. The recording is created only in browser memory for playback and is neither uploaded nor saved as a file. The microphone switches off as soon as you press Stop or leave the page.
It records, but I hear nothing on playback.
The microphone may be fine and the problem on the playback (output) side. Check the player volume, your speaker or earphone volume and the selected output device. If the level bar moved, the microphone input itself is working.
The Bluetooth earphone microphone sounds poor in the test.
Many Bluetooth earphones switch to a low-quality call mode when the microphone is on, which lowers sound quality. That is a property of the device, not of this tool. To compare, switch the input device and record the same sentence each time.
