Plays your mic through your speakers or headphones as you talk.
Use headphones to avoid feedback. Speakers will squeal.
Stay silent for 3 seconds, then talk for 7. You get a grade for background noise, speech level, clipping, and clarity.
Your last two recordings stay here, labeled with the mic and processing used, so you can switch mics or settings and compare.
- Record a clip to start comparing.
dBFS means decibels relative to full scale: 0 dBFS is the loudest level digital audio can hold, so every reading is negative. Noise floor is the level of your quietest moments over the last few seconds. Changing a processing option restarts the mic; the value on the right is what your browser reports it applied.
Run the test above on your laptop first. A No sound verdict usually means the mic-mute key is on. An error means a privacy setting is blocking the browser. A Too quiet verdict is normal for a built-in mic far from your mouth, and has its own fixes.
After you press Start, open the Mic list. If you see a headset or webcam mic as well as the built-in one, try each: the right mic may simply not be selected.
Check the laptop's mic-mute key first
Many laptops have a keyboard key that mutes the microphone in hardware, and it is easy to press by accident. When it is on, the test opens the mic but hears pure silence and shows No sound. Look for a key with a crossed-out microphone icon, often in the F-key row.
| Laptop | Mic-mute key | How to tell it is on |
|---|---|---|
| Dell Latitude and Precision (and XPS 13 9315) | Fn + F4, or F4 alone if Fn lock is set | The light on F4 is lit when the mic is muted. |
| Lenovo ThinkPad (such as T14s Gen 1, X13 Gen 1) | F4 | The key indicator is on when the mics are muted. |
| Other brands | Varies; often an F-key with a crossed-out mic | Check your model's manual or support page. |
Two details trip people up. First, on Dell's models the mute key also silences connected mics (USB, headset jack, and wireless), so plugging in a headset does not get around it. Second, the Fn lock setting changes whether you need to hold Fn, so if pressing F4 alone does nothing, try Fn + F4.

Turn on microphone privacy access
Windows and macOS both let you block the microphone for some or all apps, and your browser and call apps count as apps. If the test shows a blocked or system-level error, or your call app hears nothing, one of these privacy switches is almost certainly off.
Windows 11 laptops
- Open Start > Settings > Privacy & security > Microphone.
- Turn on "Microphone access".
- Turn on "Let apps access your microphone" and check the apps in the list.
- Turn on "Let desktop apps access your microphone". Browsers, Zoom, and Teams are desktop apps and do not appear in the list above it.
Windows 10 uses Settings > Privacy > Microphone with similar switches. Every Windows step, including the built-in Start test, is in our Windows 11 mic guide.
MacBooks
- Choose Apple menu > System Settings > Privacy & Security > Microphone (you may need to scroll).
- Turn on the switch for your browser and for each call app.
- Quit and reopen the app if it was open when you changed the switch.
The Recording Indicator in Control Center shows when an app is using the mic or used it recently, which helps you spot an app that is holding it.

Built-in mic or headset: choose the right input
A laptop can have three or more microphones at once: the built-in one, a headset, a webcam mic, and Bluetooth earbuds. Only one is the system default, and each call app can pick a different one. If the wrong one is selected, you can talk into a perfectly good mic and nothing registers.
- Windows 11: Settings > System > Sound, then under Input pick the mic in "Choose a device for speaking or recording".
- Mac: Apple menu > System Settings > Sound > Input, then select the mic from the list. The built-in mic is usually named after your Mac model.
Which should you use? For calls, a headset mic near your mouth almost always beats the built-in one, because it is closer to your voice and farther from the keyboard and fans. Use the built-in mic when you have nothing else, and the test above tells you whether its level is good enough.
A wired headset with a single plug needs a combined headset jack. Many laptops have one, but if yours has separate headphone and mic jacks, you need a splitter. The headset mic test page explains plug types.
Why laptop mics sound quiet or noisy
A built-in mic sits in the laptop body, often an arm's length from your mouth, so your voice arrives faint while keys, fans, and desk bumps arrive loud. A Too quiet verdict from a built-in mic is usually distance, not a fault. Raising the input volume helps, but moving closer helps more.
To make it louder: on Windows 11, open your input device under Settings > System > Sound and raise "Input volume". On a Mac, drag the input volume slider in System Settings > Sound > Input. Raise it in small steps and rerun the test; if the verdict jumps to Too loud, back it off.
To cut typing and fan noise: type less during calls, keep the laptop still rather than on your lap, and turn on noise suppression in your call app. Recording a clip with the test above and playing it back lets you hear exactly what others hear.
Laptop microphone not detected
If the test says no microphone was found, the laptop itself does not see the mic. On Windows, the fix is usually in Device Manager: rescan for hardware, then update or reinstall the audio driver. On a Mac, check the Sound Input list; if the built-in mic is missing there after a restart, contact Apple support.
- Restart the laptop. It releases a mic held by an app that did not close properly.
- Open Device Manager (right-click Start). Expand "Sound, video and game controllers" (mics may also appear under "Audio inputs and outputs").
- Right-click the audio device and choose "Update driver", then "Search automatically for drivers".
- Still missing? Choose "Uninstall device", tick "Attempt to remove the driver for this device", and restart. Windows reinstalls it. If not, right-click the category and choose "Scan for hardware changes".
Your laptop maker's support site may also offer an audio driver built for your exact model.
When an external USB mic is the honest fix
If the built-in mic works but always sounds distant and picks up the keyboard, no setting will move it closer to your mouth. A small USB mic on the desk in front of you solves both problems, and because it plugs into USB, it also gets around a broken or missing headset jack.

Both are condenser mics, so they still hear some of the room. Place them close. More options are on the best USB microphones page, and the full cross-device checklist is in microphone not working.
Laptop mic questions
Which key mutes the microphone on a laptop?
It depends on the maker. Dell Latitude and Precision laptops use Fn + F4, and ThinkPads such as the T14s use F4. On other laptops, look for a key with a crossed-out microphone icon, and check the manual if there is none.
Does Dell's F4 mute key also mute a headset?
Yes. Dell says the F4 mute applies to the built-in mic and to connected mics, including USB, headset-jack, and wireless ones. Turn it off before testing any mic on that laptop.
Why does my laptop say no microphone is found?
The laptop is not detecting the mic hardware. Restart first, then open Device Manager on Windows, choose Scan for hardware changes, and update or reinstall the audio driver. On a Mac, check that the mic appears in Sound Input settings.
Should I use my laptop's built-in mic or a headset for calls?
A headset, if you have one. Its mic sits near your mouth, so your voice is louder and keyboard and fan noise are quieter. The built-in mic is fine for casual calls in a quiet room.
Why does my laptop mic pick up every keystroke?
The mic is built into the same body as the keyboard, so vibration and clicks reach it directly. Use a headset or external mic, or turn on noise suppression in your call app.
Does plugging in a headset switch off the laptop's own mic?
It may become the selected input, but not always. Check the input device in your sound settings and in your call app, and pick the headset mic by name.
Why does my MacBook mic not work in Chrome?
Chrome is probably switched off under System Settings, Privacy and Security, Microphone. Turn it on, then quit and reopen Chrome, which Google says may be needed after changing Mac permissions.
How do I turn off my laptop microphone completely?
Press the mic-mute key if your laptop has one. On Windows 11 you can also turn off Microphone access under Privacy and security, and on a Mac you can switch off each app under Privacy and Security, Microphone.
Can I use AirPods as a microphone on a Windows laptop?
Yes. AirPods pair with Windows as a Bluetooth headset that supports talking as well as listening. Choose the hands-free entry as your input, and expect lower audio quality while the mic is in use.
Is a USB microphone better than a laptop's built-in mic?
For calls and recording, almost always. A USB mic sits closer to your mouth and away from the keyboard and fans, so it captures more voice and less noise. It also works if the laptop's mic or headset jack has failed.
