Question 1

How does the mic test work?

Accepted Answer

Our mic test uses your browser's Web Audio API to access your microphone and analyze the audio input in real time. It measures audio levels and clarity feedback without uploading or storing your audio on our servers.

Question 2

Why is my microphone not working?

Accepted Answer

Common causes: browser microphone permission blocked, mic muted in system settings, another app using the mic (Zoom/Teams/Discord), outdated drivers, or a bad cable/USB port. Allow access in the address bar, close other apps, then retry the mic test.

Question 3

Why does my mic work here but not in Zoom or Teams?

Accepted Answer

Apps often use a different input device or their own gain settings. In Zoom/Teams, open audio settings and select the same microphone that works in this mic test. Also disable exclusive mode in Windows sound device properties if levels drop to zero in meetings.

Question 4

What audio levels should I aim for?

Accepted Answer

Aim for roughly 30–70% on the meter. Below ~30% can sound quiet; above ~70% risks clipping. Speak at a normal distance (about 15–20 cm / 6–8 inches) and adjust system input gain until the level stays in the good range.

Question 5

Is my audio recorded or stored?

Accepted Answer

Optional local recording/playback stays in your browser session. We do not upload microphone audio to MicTest.to servers for the test itself. See our Privacy Policy for details.

Question 6

Which browsers support the mic test?

Accepted Answer

Chrome, Edge, Firefox, and Safari on desktop; Chrome and Safari on most mobile devices. Use HTTPS (or localhost) — browsers block microphone access on insecure pages.

Question 7

How do I fix mic permission denied in Chrome?

Accepted Answer

Click the lock/tune icon in the address bar → Site settings → Microphone → Allow. If the OS blocked Chrome, enable microphone access for Chrome in Windows Privacy or macOS System Settings → Privacy & Security → Microphone.

Question 8

My mic works on Windows but not on Mac (or vice versa).

Accepted Answer

Check OS privacy permissions for the browser, confirm the correct input device is selected, and test after unplugging/replugging USB mics. On Mac, reset TCC microphone permission for the browser if needed.

Question 9

Why is there background noise or echo?

Accepted Answer

Reduce fan/keyboard noise, move closer to the mic, enable noise suppression/echo cancellation in browser or OS settings, and avoid speakers playing your voice (use headphones). Our sound and speaker tests can help isolate playback issues.

Question 10

Can I test different microphones?

Accepted Answer

Yes. Choose another device from the microphone dropdown (after granting permission) or change the default input in your OS, then start the mic test again.

Question 11

What if the test shows Too Loud or Too Quiet?

Accepted Answer

Too loud: lower mic gain, move farther away, or disable automatic gain if it pumps. Too quiet: raise input volume, speak closer, unmute the device, and ensure you selected the right mic — not a virtual cable or monitor loopback.

Question 12

Does Discord or OBS need a separate mic check?

Accepted Answer

Use this mic test to confirm hardware and browser access first. Then match the same device in Discord Voice & Video or OBS Audio Input Capture. If the browser test passes but Discord fails, the issue is app routing or Discord permissions—not the microphone itself.

Question 13

Can I use this mic test on my phone?

Accepted Answer

Yes on modern mobile browsers. Grant microphone permission when prompted. For best results use Chrome/Safari, close other apps using the mic, and hold the phone like a normal call distance.

Question 14

What's the difference between mic test, speaker test, and sound test?

Accepted Answer

Mic test checks your microphone input. Speaker test plays tones through your speakers/headphones to verify output. Sound test combines level checks for hearing playback clearly. Use all three before important calls or streams.
