About Mic Test
This page tells you within a second whether your microphone works: a live level meter in decibels and a moving waveform react as soon as you speak.
It also gives you a clear verdict: working, silent, too quiet or clipping, so you know what to fix before a call, a lesson or a recording.
Record five seconds and play them back to hear exactly what others hear, with or without the echo cancellation and noise suppression that call apps apply.
Key Features
- Live level meter: the input level in dBFS with the loudest moment held for a second and a half.
- Waveform view: see the signal move as you talk, so a dead or crackling mic is obvious at a glance.
- Clear verdict: working, no sound, very quiet or clipping, with what to change in each case.
- Playback test: record five seconds and listen back on your speakers or headphones.
- Device details: the microphone’s name, sample rate, channels and the processing your browser applies.
- Any microphone: switch between built-in, USB, headset and Bluetooth mics without reloading.
How to Use
- Press Start test: allow microphone access when your browser asks.
- Pick the device: choose the microphone you want to check if you have more than one.
- Speak normally: the meter should reach the green area and the verdict should turn to working.
- Record a sample: press Record 5 seconds and play it back to judge the sound.
- Compare settings: switch echo cancellation and noise suppression off and on to hear what calls do to your voice.
Common Use Cases
- Before a video call: check the right mic is selected for Zoom, Teams, Meet or Discord.
- New headset or USB mic: confirm it works and is loud enough before you rely on it.
- Troubleshooting silence: find out whether the problem is the mic, the mute switch or the app.
- Recording and streaming: set your input volume so speech is strong without clipping.
- Online exams and interviews: make sure you will be heard before the session starts.
Frequently Asked Questions
Is my voice recorded or uploaded?
No. The level meter only reads the signal as it passes, and the 5-second sample stays on your device until you leave the page.
Why does the meter not move?
Check that the microphone is not muted (many headsets have a switch), that its input volume is up in your system settings, and that the right device is selected above.
What level should my microphone reach?
Normal speech should land between about -30 and -12 dBFS. Above -3 dBFS it starts to distort; below -45 dBFS listeners will struggle to hear you.
Why can I not choose another microphone?
Browsers list your microphones only after you allow access once. Press Start test, allow it, and every connected microphone appears.
What do echo cancellation and noise suppression change?
They are the filters call apps use. With them on, background noise is lowered and your voice can sound slightly thinner; turn them off to hear the raw microphone.
Does it work on phones?
Yes, in current mobile browsers. On iPhone and iPad, Safari asks for permission each time you start the test.
Pro Tips
- Watch the peak, not the needle: the loudest value tells you whether a sudden laugh would clip.
- Mind the distance: about a hand’s width from a headset mic, 15 to 30 cm from a desk mic.
- Close other tabs first: an open call in another tab can hold the microphone and block the test.
- Use headphones for playback: speakers can feed back into the microphone while you listen.
- Test your camera too: the webcam test checks picture, resolution and frame rate the same way.
