How can I test my microphone online?

Click the mic button, allow access when prompted, and watch the live waveform and volume bars move with your voice.

Is this microphone test private?

Yes. Everything runs on your device in the browser. No audio is uploaded or recorded.

Why can’t my browser detect a microphone?

Allow mic access in site settings, confirm the mic is connected, and close other apps like Zoom or Teams that may be using it.

How do I fix low microphone volume?

Increase the sensitivity slider, raise system mic input in OS settings, or switch to a different input device.

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

Echo cancellation reduces feedback, noise suppression lowers background hiss, and auto gain keeps your level steady.

How to use the microphone test

1) Start the test

Click the mic button. When prompted, choose Allow. The waveform and bars will animate if your mic is active.

2) Pick the right input

Use the Microphone dropdown to choose built-in, headset, USB, or Bluetooth mics. Try multiple if you’re unsure.

3) Set levels

Adjust Sensitivity so average speech drives the bars to the middle/high range without constantly maxing out.

4) Improve clarity

Toggle Echo cancel, Noise suppr., or Auto gain if you’re in a noisy room or hearing feedback.

What this mic test measures

Peak shows the highest instant level. RMS is the average loudness over time. Aim for strong RMS without constant 100% peaks. If peaks hit 100% and the sound distorts, lower sensitivity or move the mic farther from your mouth.

Privacy & permissions

Audio stays on your device and is processed in your browser. Nothing is uploaded or stored. To revoke access, open your browser’s site settings and remove the microphone permission.

Keep troubleshooting

Eject water from speaker if the sound is muffled after a splash.
Run the speaker test to check for distortion, rattles, or imbalance.
Try a quiet room and move cables/adapters—ground loops and loose jacks can cause hum or buzz.
On Windows or macOS, open system sound settings and ensure the correct input is selected and not muted.
