Microphone Test — Check Your Mic Online
Test your microphone in the browser: live input-level meter, 15-second peak history, echo test, and instant device switching. Audio never leaves your device.
Start the test, allow mic access, and watch the level meter react to your voice.
Private by design: your voice is measured on this page only — the audio is never recorded, stored, or uploaded. The echo test plays your mic straight back to your speakers locally.
Reading the meter
Speak at your normal call volume: a healthy mic should push the bar into the yellow (50–85%) on peaks without pinning red. Whisper should still move it above green. If the meter barely moves, pick another device from the dropdown (webcams often expose their own mic), then check the input level in your OS sound settings — a system-level input volume of 70–100% is a good baseline.
The peak history strip keeps the last 15 seconds so you can step away, talk, and come back to see what happened. The echo test routes your mic back to your speakers: you should hear yourself instantly. Hearing nothing means the wrong device is selected or system output is muted — your mic itself can still be fine.
Quick Answer
This free microphone test shows a live input-level meter the moment you allow mic access. Speak normally and watch the bar react, review 15 seconds of peak history to spot dropouts, switch between microphones without re-granting permission, and run an echo test to hear your own voice. Everything runs on your device — no audio is recorded or uploaded.

Click "Start mic test" and allow microphone access when your browser asks
Speak at normal volume and watch the live level meter react
Check the peak history strip — dips mean dropouts, constant red means clipping
Toggle the echo test to hear your own voice back through your speakers
Switch microphones from the dropdown to compare your headset, webcam, and built-in mic

Frequently Asked Questions
Is my microphone audio being recorded or uploaded?
No. The test analyses your microphone signal in real time inside your browser to drive the level meter — the audio is never recorded to a file, stored, or sent anywhere. You can verify this in your browser: the tab shows "recording" only while you are actively testing, and it stops the moment you press Stop or close the page.
Why is my microphone not working?
Check in this order: (1) the browser has mic permission — click the lock or mic icon in the address bar and set the microphone to "Allow"; (2) the right device is selected — webcams and headsets often expose their own microphones, so pick another entry in the dropdown; (3) the mic is not muted in hardware (a physical switch) or in your OS sound settings, and the input volume is up; (4) another app (Zoom, Teams, Discord) is holding exclusive access — close it; (5) on desktop, check the OS privacy setting allows your browser to use the microphone.
What is a good microphone input level?
Speak at your normal call volume: a healthy setup pushes the meter into the yellow zone (roughly 50–85%) on speech peaks without sitting pinned in the red. If you only reach 10–20%, raise the input level in your operating system sound settings or move closer to the mic. Constant 100% red means the input is too hot and your voice will clip on calls.
What does the echo test do?
It routes your microphone input straight back to your speakers, locally. If you hear yourself immediately after pressing the toggle, both your mic and your output device work — the classic "can you hear me?" check, without a second person. Use headphones so your speakers do not pick up the playback and create feedback howling.
Can I test a headset or an external USB microphone?
Yes. After the first permission grant, every input device — built-in mic, webcam mic, headset, USB interface — appears in the dropdown, and switching between them never asks for permission again. The peak history resets on each switch so readings always belong to the selected device.
