Mic Test: Check Your Microphone Online
Test your mic in seconds. Click start, allow access, and speak: if the meter moves, your microphone works. You can also record a short clip and play it back. Everything runs in your browser, and no audio ever leaves your machine.
Your recording (this is how you sound to others):
Private by design: audio is processed locally with the Web Audio API. Nothing is uploaded or stored.
Your mic works. Put it to use.
You already have working audio. Two free ways to use it today: record your screen and camera in the browser with Recording Studio, or write 3x faster on your Mac by dictating with OpenFlow.
How do I test my microphone online?
- Click the Start mic test button above.
- When your browser asks for permission, click Allow.
- Speak normally. If the volume meter moves, your mic is working.
- Optional: click Record 5s clip, then play it back to hear how you actually sound to other people.
The whole check takes about ten seconds and works with built in laptop mics, USB microphones, XLR interfaces, headsets, and AirPods.
Why is my mic not working?
- Permission blocked: click the camera/mic icon in your browser's address bar and set microphone access to Allow, then reload.
- Wrong input selected: use the Microphone dropdown above to switch devices. Laptops often default to an internal mic even when a USB mic is plugged in.
- Hardware mute: many headsets and mics have a physical mute switch or a tap to mute area. Check it.
- Another app has the mic: close Zoom, Teams, Discord, or OBS and try again.
- System settings: on macOS check System Settings, Privacy and Security, Microphone. On Windows check Settings, Privacy, Microphone.
Frequently asked questions
Is my audio uploaded anywhere?
No. This test runs entirely in your browser using the Web Audio API. Your audio never leaves your machine, nothing is uploaded, and nothing is stored after you close the tab.
Why does my mic sound quiet?
Raise the input volume in your system sound settings, move the mic closer to your mouth (a hand's width is a good starting point), and make sure you are speaking into the correct side of the mic. USB and XLR mics often have a physical gain knob too.
Which browsers does this work in?
Any modern browser: Chrome, Edge, Firefox, Safari, Brave, and Arc, on desktop and mobile.
What is a good level on the meter?
Aim for the meter to sit in the middle zone while you speak normally, with peaks near the top only when you get loud. If it is pinned at the top constantly, lower your gain: your audio is likely clipping.
