This microphone test checks in a few seconds whether your mic works, how loud it picks you up and how you sound. Press Start, accept the browser prompt, and a live meter shows your input level in decibels. Then record 5 to 10 seconds and play it back. The HypestKey mic test runs in your browser and uploads nothing.
How do I test my microphone online?
Open the microphone test, press Start microphone and choose Allow in the browser prompt. Speak at your normal volume from 20 to 30 cm away. If the meter moves and speech peaks land between about -40 and -6 dB, the mic works. Record 8 seconds and listen to check the sound itself.
The meter answers “does it work?”. The recording answers “how do I sound?”: hiss, hum, echo, a muffled voice or sound that cuts in and out are easier to hear than to measure.
How to use the microphone test
- Plug in your headset or USB microphone before you open the page, if you use one.
- Press Start microphone and choose Allow in the browser prompt.
- Pick your microphone in the Microphone list if the page opened the wrong one.
- Speak at your normal volume and watch the meter and the Input level value.
- Choose a recording length of 5, 8 or 10 seconds and press Record.
- Say a few sentences, wait for the recording to stop and press play to listen.
- Press Stop microphone when you are done. The browser releases the mic at once.
What is a good microphone level in dB?
For speech, aim for peaks between about -20 and -6 dB on this meter. 0 dB (dBFS) is the loudest a digital signal can get, so readings are negative. Peaks that touch 0 dB clip and distort. A level that stays under -40 dB is so quiet that other people will turn you up and hear more noise.
| Input level while you speak | What it means | What to do |
|---|---|---|
| Below -60 dB | Silence: the mic is muted, off or not the one in use | Check the mute switch, pick another mic, check system settings |
| -60 to -40 dB | Very quiet | Move closer, raise the input volume |
| -40 to -20 dB | Usable, a little low | Fine for most calls; a bit closer is better |
| -20 to -6 dB | Good level for calls and recordings | Keep it |
| Peaks at 0 dB | Clipping, the sound distorts | Lower the input volume or move back |
These ranges are a practical guide for voice, not a formal standard. Music and loud games need more headroom.
Why is my microphone not working in the browser?
In most cases the browser or the operating system blocks access. Chrome and Safari remember a “Block” choice per site, Windows 11 has a separate switch for desktop apps, and macOS lists every app that may use the mic. A mic held by Zoom, Teams or Discord can also fail to start.
The test names the exact error and shows the fix. The common ones:
- Access blocked (NotAllowedError): in Chrome or Edge, click the icon left of the address, open Site settings and set Microphone to Allow. In Safari on a Mac, go to Safari → Settings → Websites → Microphone.
- Windows 11: Settings → Privacy & security → Microphone. Turn on Microphone access and Let desktop apps access your microphone. Browsers count as desktop apps.
- macOS: System Settings → Privacy & Security → Microphone. Turn on your browser, then quit and reopen it.
- iPhone or iPad: Settings → Apps → Safari → Microphone (on iOS 17 and older: Settings → Safari → Microphone).
- No microphone found (NotFoundError): the system sees no input device. Check the cable, the USB port and the input list in your sound settings.
- Could not start (NotReadableError): another app holds the mic or a driver failed. Close other call apps and replug the mic.
Is it safe to test a microphone online?
Yes, on this page. The HypestKey microphone test measures the sound inside your browser tab and sends nothing to a server: no audio, no recording, no level data. The recording is a temporary file in memory that disappears when you close or reload the page. The mic turns on only after you press Start.
You can also see this in the browser itself: Chrome, Edge, Firefox and Safari show a mic icon in the tab or address bar while any page uses the microphone, and it goes away when you press Stop.
How this tool works
When you press Start, the page asks for the microphone with the browser’s getUserMedia function. It asks to switch off echo cancellation, noise suppression and automatic gain, so the meter shows what the microphone really delivers. Video calls usually keep those filters on, so you may sound a bit cleaner and more even there.
The Web Audio analyser reads 2,048 samples at a time, about 60 times per second. Input level is the RMS (average power) of those samples in dBFS. Peak is the highest single sample, held for 1.5 seconds. Volume maps -60 dB to 0% and 0 dB to 100%. Sample rate and channels come from the browser; 48 kHz mono is typical.
The recording uses the browser’s MediaRecorder: Chrome, Edge and Firefox usually save Opus in WebM, Safari saves AAC in MP4. The result is a local Blob link for the player and is never uploaded. The limits: a browser cannot measure the absolute loudness of your room, only the digital level after the mic and the system input volume, so the same voice reads differently on different gain settings.
Can I test a headset or Bluetooth microphone?
Yes. Any input device your system lists shows up in the Microphone list after you grant access, including USB mics, headsets, webcams with built-in mics and Bluetooth earbuds. Bluetooth headsets switch to a lower quality call mode while the mic is in use, often 16 kHz, so they sound duller than a wired mic.
If the list changes while the test runs, for example when you plug in a headset, the page updates it on its own. Choosing another entry restarts the test with that device.
