To test a microphone, open a mic test, allow access, and speak at your normal distance: if the level meter moves, the mic works. Then check the level: for speech, peaks between about -20 and -6 dB are healthy, a meter that barely moves means the mic is too quiet, and anything touching 0 dB is clipping. Finally, record a few seconds and play it back to hear echo, noise or muffled sound.

Here's how to do that in a browser, in Windows and on a Mac, what each reading means, and how to fix the usual problems: a quiet mic, the wrong mic selected, or no sound at all.
The short answer
Open the free mic test, allow microphone access, speak for a few seconds and watch the meter. Peaks around -20 to -6 dB are good; near -40 dB or lower is too quiet (move closer or raise the input level); 0 dB is clipping (turn it down). Record 5 seconds and listen back. If the meter doesn't move, check the input device, mute switches and the browser's and system's microphone permissions.
Key takeaways
- A level meter answers "does it work?"; a playback answers "does it sound good?". Do both.
- dBFS runs from 0 (the maximum) downwards; -6 dB is half the maximum amplitude.
- Most quiet-mic problems are distance, a low input level, or the wrong device selected.
- Browsers need permission per site; Windows and macOS also have system-wide microphone privacy switches.
- Echo cancellation and noise suppression change how you sound; test with them on and off.
How do you test a microphone online?
You test a microphone online by letting a web page read its level and record a short sample. With QuickVeed's free mic test:
- Press Test my microphone and choose Allow when the browser asks.
- Pick the mic from the list if you have more than one (built-in, USB, headset).
- Speak at your normal distance and volume. Watch the live level in dB and the loudest peak.
- Press Record 5 seconds, then play it back with headphones.
- Toggle echo cancellation and noise suppression to hear the raw mic versus how you'd sound on a call.
The meter shows peak level from -60 to 0 dBFS with a peak hold, and the panel lists the sample rate, channels and device name. Sound stays in your browser; the test clip is never uploaded.
What is a good microphone level?
A good microphone level for speech has peaks around -20 to -6 dB on a dBFS meter, which leaves room for louder moments without clipping. Here's how to read the meter:
| Loudest peaks (dBFS) | What it means | What to do |
|---|---|---|
| 0 dB, clipping warning | Too loud: the signal is cut flat and distorts | Lower the input level or move back |
| -6 to -3 dB | Hot; fine for steady speech, risky if you laugh or shout | Turn down a little for safety |
| -20 to -6 dB | Healthy speech level | Leave it |
| -30 to -20 dB | On the quiet side; usable, will need a boost | Move closer or raise the input |
| Below -40 dB | Too quiet; noise will be loud after boosting | Check distance, input level, device |
| Flat, no movement | No signal reaching the browser | See the troubleshooting table below |
Every -6 dB halves the amplitude, so a voice peaking at -30 dB is about one-sixteenth of the way to full scale. You can rescue a quiet recording later with the free audio volume booster (see how to make audio louder), but noise rises with it, so it's better to fix the level now.
How do you test a mic on Windows?
On Windows 11, open Settings > System > Sound and look under Input:
- Choose your microphone under Choose a device for speaking or recording.
- Open the device's properties to see the Input volume slider and the microphone test.
- Speak and watch the input level bar; raise the input volume if it barely moves.
- If nothing registers, open Settings > Privacy & security > Microphone and make sure microphone access, and access for desktop apps (your browser), is on.
Microsoft's support page on microphone problems walks through the same checks, including privacy settings and drivers.
How do you test a mic on a Mac?
On a Mac, choose Apple menu > System Settings > Sound, then click Input:
- Select the microphone in the list of input devices.
- Speak and watch the Input level meter; it should light up as you talk.
- Drag the Input volume slider to raise or lower the level.
- If a browser can't hear you, open System Settings > Privacy & Security > Microphone and turn it on for Chrome, Safari or Firefox (you may need to restart the browser).
Apple's guide to Sound Input settings documents the input level meter and volume slider.
Why is my mic so quiet?
A mic is usually quiet because it's too far away, its input level is low, or the computer is listening to a different mic. Work down this list:
| Cause | How to check | Fix |
|---|---|---|
| Too far from your mouth | Level jumps when you lean in | Keep the mic about a hand's width to 30 cm away |
| Input volume low | System input slider near the left | Raise it in Windows Sound or Mac Sound > Input |
| Wrong mic selected | Device name in the test isn't the one you're using | Pick the right device in the browser and the system |
| Gain knob low (USB or interface) | Hardware gain turned down | Turn the gain up until peaks reach about -12 dB |
| Speaking into the wrong side | Side-address mics pick up from the side | Check the manufacturer's diagram |
| App auto-gain or sensitivity | Quiet only in one app | Turn off auto-adjust or lower the sensitivity threshold in that app |
Why is my microphone not working at all?
If the meter stays flat, the sound isn't reaching the browser. Google's Chrome help lists the main checks: that you're not muted (including a headset switch), that the site has permission, and that the right default device is set in your system settings.
- Permission blocked: click the icon at the left of the address bar and allow the microphone, or open Chrome Settings > Privacy and security > Site settings > Microphone.
- System privacy: Windows and macOS each have a Microphone privacy switch for apps (see above).
- Muted hardware: headset mute switches, a mute key on the keyboard, or an inline remote.
- In use elsewhere: close Zoom, Teams, Discord or OBS, which can hold the device.
- Cable or port: try another USB port, or another device to rule out a faulty mic.
- Restart: quit and reopen the browser after changing permissions; restart the computer if the device still isn't listed.
How do you get better sound once the mic works?
Once the level is right, the room and the distance matter more than the mic. Record in a small, furnished room rather than a bare one; keep the mic at the same distance throughout; and record a short test before every session. For video, record yourself with the free webcam recorder or screen recorder, or audio only with the voice recorder, which has noise reduction and saves M4A, WebM or WAV. Setting up a show? How to start a video podcast covers mics, rooms and recording, and how to record audio on a computer compares the free recorders.
Frequently asked questions
How do I test my mic?
Open a mic test, allow access and speak. If the meter moves, it works; record 5 seconds and play it back to hear the quality.
What should my mic level be in dB?
For speech, peaks around -20 to -6 dBFS. 0 dB is clipping; below about -40 dB is too quiet.
Why is my mic so quiet on Windows?
Usually a low input volume or the wrong device. Check Settings > System > Sound > Input, and move the mic closer.
How do I test my mic on a Mac?
Open System Settings > Sound > Input, select the mic and watch the input level meter as you speak.
Why can't my browser hear my microphone?
The site permission or the system's microphone privacy switch is blocking it, or another app is using the mic.
Is my test recording uploaded?
Not with QuickVeed's mic test: the level is measured and the 5-second clip played back in your browser only.
