How to use Mic test
Start the test
Press Start and allow the microphone when your browser asks. If you have more than one, pick the one you want to test.
Speak and watch
Talk normally. The waveform and level meter move, and “We can hear you” shows once your voice comes through clearly.
Hear yourself
Record 5 seconds and play it back to hear how you sound to others, or turn on playback with headphones to listen live.
Why use Utils365
Private by design
Sound is measured in your browser. Nothing is uploaded, the test recording lives in memory only, and the mic turns off when you stop.
Clear answers
A live meter, a peak level in decibels and a plain “we can hear you” tell you at a glance whether the mic is picking you up.
Every microphone
Switch between a laptop mic, a USB microphone, a headset or AirPods, and compare them with noise suppression on or off.
Explains what went wrong
Blocked access, no microphone found or a mic busy in another app each get a clear message and what to do next.
Frequently asked questions
How do I test my microphone?
Press Start, allow the microphone, and speak. If the waveform moves and the status says “We can hear you”, your mic works. Record 5 seconds and play it back to hear the quality.
Why is my microphone not working?
The most common causes are blocked browser permission, the wrong input chosen, a mute switch on the headset, or another app such as Zoom or Teams holding the mic. The test tells you which of these it detects.
How do I allow microphone access in my browser?
Click the lock or mic icon at the left of the address bar and set Microphone to Allow, then press Start again. On a Mac, also allow your browser in System Settings › Privacy & Security › Microphone.
What is a good microphone level?
Normal speech usually peaks between about −20 dB and −6 dB. If the peak reaches 0 dB the sound clips and distorts; if speech stays below −40 dB, move closer or raise the input volume.
Is my voice recorded or uploaded?
No. The level is measured in your browser and nothing is sent anywhere. The optional 5-second test recording is kept in memory and disappears when you leave the page.
Why do I hear an echo or a howl?
With playback on, your speakers feed back into the mic. Use headphones, or leave playback off and use the record-and-play-back check instead.
What do noise suppression and echo cancellation do?
They are the filters most video calls use. Noise suppression cuts steady background noise like fans, and echo cancellation removes sound from your speakers. Turn them off to hear the raw microphone.
