Frequently asked questions
How do I test my microphone online?
Click the Test Microphone button on this page. Your browser will ask for microphone permission. Once granted, the volume meter shows your mic's input level in real time. Speak into your mic to confirm it works.
Why is my microphone not working?
Common causes: the browser blocked microphone access (check the address bar for a blocked icon), the wrong input device is selected in your system settings, or the mic is muted at the hardware level. This tool shows the detected device name to help you troubleshoot.
Does this tool record or store my audio?
No. The microphone signal is processed entirely in your browser for the volume meter. If you choose to record a test clip, that recording stays on your device. Nothing is uploaded or stored on any server.
Can I test my mic on my phone?
Yes. This tool works in any modern mobile browser that supports microphone access, including Safari on iPhone and Chrome on Android.
What does the volume meter show?
The meter shows the RMS (root mean square) volume level of your microphone input in decibels. A higher level means louder input. If the bar moves when you speak, your mic is working.
Can I record a test clip?
Yes. After starting the mic test, click the Record button to capture a few seconds of audio. Play it back to hear how your mic sounds, or download it as a WAV file.
My mic is quiet on Discord. Will this tool tell me why?
This tool shows your mic's RMS level in real time. If the bar barely moves at normal speaking volume, your system input gain is too low. Go to your OS sound settings, find the input level for your mic, and raise it. Test again here to confirm it improved.
How do I test my microphone before a Zoom or Google Meet call?
Open this page, click Test Microphone, and speak. If the volume meter moves and playback sounds clear, your mic is working. This catches problems before your call starts, so you are not the person saying "can you hear me?" for the first two minutes.
How do I test my microphone on a Chromebook without installing anything?
Open this page in Chrome on your Chromebook and click Test Microphone. Chromebooks run Chrome natively, so the mic test works instantly. You do not need to install anything or request admin permissions.
Why does my mic sound muffled or quiet?
Common causes: the mic is too far from your mouth, a case or cover is blocking the microphone hole, or your system input volume is set low. Use this tool to check your volume level in real time. If the meter barely moves when you speak at normal volume, increase your system mic level in Settings > Sound.
