Hear it for yourself

Record a short clip and listen back, or hear yourself live. Use headphones for live listening to avoid a loud feedback howl.

Start the test first, then record.

How to test your microphone

Run the test

Click Start and allow microphone access when your browser asks. Nothing is requested until you click. Speak at your usual volume and watch the meter and waveform move. If you have more than one microphone, pick it from the list; switching restarts the test on that device.

Press Record 5 seconds, say a short sentence, then play it back to hear how you sound. Click Stop when you are done to release the microphone.

Read the meter

The number is the signal's RMS level in dBFS (decibels relative to digital full scale). It is always zero or negative; closer to zero means a stronger signal. It is a digital input level, not a calibrated measurement of how loud your room is.

The display bottoms out at −100 dBFS. "Sound detected" appears when the level rises above −60 dBFS, so steady background noise can trigger it too. Peaks near full scale show a clipping warning: lower the input gain or move back from the mic.

Microphone not working? Check these first

Browser permission. If access was blocked, open the site permissions from the icon next to the address bar, allow the microphone, and press Start again. Microphone access only works on secure (HTTPS) pages.

The right device. A webcam, laptop and headset can each appear as a separate microphone. Choose the one you mean to use, check a headset's mute switch and cable, and close other calling or recording apps if the mic is reported as in use.

Windows and macOS settings

Windows: open Settings → Privacy & security → Microphone (Privacy on older versions) and make sure microphone access, including access for desktop apps, is on. Then check the input device under Sound settings.

macOS: open System Settings → Privacy & Security → Microphone and allow your browser (System Preferences on older versions). You may need to restart the browser. Check the selected input under Sound → Input.

Mic test FAQ

My mic works here but not in Zoom, Discord or Teams. Why?

Each app picks its own input device. In Zoom open Settings → Audio, in Discord User Settings → Voice & Video, and in Teams Settings → Devices, then choose the same microphone that works on this page. Also check that the app is allowed to use the microphone in your system privacy settings, and close other apps that may be holding it.

What do echo cancellation, noise suppression and auto gain mean?

They are clean-up steps the browser applies before a call hears you. Echo cancellation removes your speakers' sound from the mic, noise suppression cuts steady background noise, and auto gain raises or lowers your level automatically. The table shows which ones are on. Tick the box above it to hear your microphone without them.

Why is my microphone so quiet?

Normal speech should land roughly between −30 and −10 dBFS on the meter. If it stays lower, raise the input volume in your system sound settings, move closer to the mic, and check that you are speaking into the right side of it. Some headsets also have a hardware mute switch or volume wheel.

Can I hear myself through my mic in real time?

Yes. Put headphones on, then tick Hear yourself live. Without headphones the speakers feed back into the mic and cause a howl. Bluetooth headphones add a short delay, so a slight echo is normal with them.

Is my recording uploaded anywhere?

No. The recording is made and stored in your browser's memory only. It disappears when you leave or reload the page, unless you choose Save recording to download it to your device.
