Microphone Test

How to Use This Test

1. Click Start microphone test and hit Allow when your browser asks for permission. The test cannot access your mic until you grant this.
2. Speak at your normal volume. Watch the level bar — it should rise and fall as you speak.
3. Watch the waveform. It draws your voice in real time as a wave pattern. A completely flat line means no audio is reaching the test.
4. Click Record, say a few sentences, then click Stop and hit play to hear the playback. This is what you actually sound like on calls.
5. If you have more than one mic connected, use the device dropdown to switch between them and compare.
6. Run the test at least twice if results seem inconsistent — background noise and other apps can interfere with the first reading.

What Your Results Mean

Level bar moving steadily in the green zone: Your microphone is working and input volume is at a healthy level. This is what you want to see.

Level bar barely moves when you speak: You're coming through too quietly. The mic may be too far away, the input gain in system settings is low, or the wrong device is selected.

Level bar hits the red or clips: You're too loud. This causes distortion on calls. Lower your input volume in system settings or move the mic further from your mouth.

Waveform completely flat with meter at zero: The browser isn't receiving any audio. Permission was denied, the mic is muted in your OS settings, or the wrong input device is selected.

Recording sounds thin, distant, or echoey: You're picking up room reverb. Move closer to the mic and record somewhere with soft furnishings — carpet, curtains, and sofas absorb reflections.

Recording sounds muffled: The mic is too close to a surface, blocked by a case, or aimed the wrong way. Most mics are directional — point the front of the mic at your mouth.

Common Problems and Fixes

Meter stays at zero even after granting permission

Look at the address bar. If you see a blocked mic icon, click it, set microphone access to Allow, then reload. In Chrome, go to Settings → Privacy and security → Site settings → Microphone.

Input level too low even at maximum

Open your OS audio settings and raise the mic volume there. On Windows: right-click the speaker icon → Sound settings → Input → select your mic → raise the level. On Mac: System Settings → Sound → Input.

Wrong microphone is selected

Laptops often default to the built-in mic even when a headset is plugged in. Use the dropdown on this page to switch to the correct device.

Mic works here but Zoom or Teams can't hear you

Each app has its own audio permission and input device setting. Open that app's audio preferences and select your microphone. On Windows, also check Settings → Privacy & Security → Microphone and confirm the app is allowed.

Echo or feedback during recording

Your speakers are being picked up by the mic. Switch to headphones to prevent the loop. If you hear echo from others during a live call, the echo is coming from their end.

Mic cuts out mid-test

Another app (Zoom, Discord, Skype) may have reclaimed the mic in exclusive mode. Close all other audio applications and try again.

Why This Test Matters

A microphone that appears to work in your OS settings can still fail silently in a browser call. Testing here — with a live waveform and a recording you can listen to — gives you information your system settings can't. You hear what other people hear, before the call starts.

This matters most before job interviews over video call, where audio problems create a poor first impression. It matters for content creators who record voiceovers and need to catch reverb or noise before editing. And it matters when you buy a new headset and want to confirm it's working before you need it.

If something fails in a specific app later and the test shows your mic is fine, you know the fix is in that app's settings — not in the hardware.

Why Microphone Problems Happen

When a mic misbehaves, the cause is almost always one of six things. Most take under a minute to rule out, and you can usually do it without restarting anything.

1. The system is listening to the wrong input. Plug in a headset and your computer often keeps using the laptop's built-in array mic instead. On Windows 11 24H2, open Settings → System → Sound, and under Input choose the device you actually want, then watch the "Test your microphone" bar respond as you talk. On macOS Sequoia, go to System Settings → Sound → Input, select the device, and watch the input-level dots light up.

2. Input volume sits too low. On Windows 11, open Settings → System → Sound, click your input device, and raise the Input volume slider. If it's already maxed and you're still faint, click "More sound settings," open the Recording tab, double-click your mic, and add gain on the Levels tab — the Microphone Boost control there can add 10–30 dB. macOS keeps it simpler: the single Input volume slider in Sound is the only level control, so push it toward the top.

3. A privacy permission is blocking it. Windows 11: Settings → Privacy & security → Microphone, then confirm "Microphone access" is on and that your browser or app appears enabled in the list below. macOS Sequoia: System Settings → Privacy & Security → Microphone, then switch the relevant app on. Sequoia will sometimes prompt again after an update, so re-checking here fixes a mic that "suddenly" died.

4. A physical mute is engaged. Plenty of headsets — HyperX, Logitech, Jabra — mute when you flip the boom arm up or tap an inline button. A hardware mute never shows in software, so it's the first thing to check on a headset that reads as connected but silent.

5. Another app grabbed the mic. Discord, Zoom and OBS can hold a microphone so nothing else can read it. If the meter here stays flat while one of those is open, close it completely (check the system tray) and retest.

6. A driver or Bluetooth profile glitch. On Windows, right-click Start → Device Manager → expand "Audio inputs and outputs," right-click your mic and choose "Update driver," or uninstall it and reboot to force a clean reinstall. With Bluetooth headsets the mic only works in the low-bandwidth "Hands-Free" profile — which is exactly why your music drops to a tinny quality the instant the mic activates.

It Works Here But Not in Zoom, Teams or Discord

If the waveform moves on this page, your hardware is fine and the problem lives inside the app. Every conferencing tool keeps its own input device and its own mute state, completely separate from the operating system, and that's where these failures hide.

In Zoom, open Settings → Audio and confirm the correct device under Microphone; if your level swings wildly, turn off "Automatically adjust microphone volume." In Microsoft Teams, it's the "…" menu → Settings → Devices → Microphone. In Discord, go to User Settings → Voice & Video, set the Input Device, and watch the "Mic Test" bar — if Input Sensitivity is on Automatic and the bar never lights, switch to manual and drag the threshold left. In Google Meet and other browser calls, there are two gates: the in-app gear → Audio setting, and the browser's own site permission, which you reach by clicking the lock or tune icon in the address bar. A mic that passes here but fails in one app almost always has the wrong device selected in that one app.

How to Get the Best Microphone Results

1. Stay about a hand-span away — roughly 15–20 cm. Closer than that and you get bass-heavy boominess and popping; much farther and the room takes over. A headset boom should sit just below your bottom lip, not directly in front of your mouth.
2. Speak slightly across the mic, not straight into it. Aiming a little off-axis lets the bursts of air from "p" and "b" sounds pass beside the capsule instead of thumping it.
3. Aim for the level bar to peak around two-thirds. That leaves headroom so a sudden laugh or loud word doesn't clip into distortion. If you're regularly hitting the red, drop your input volume by 10–15%.
4. Cut noise at the source. A desk fan a metre away, a mechanical keyboard, or an open window all bleed in. Move the fan, switch to a quieter typing moment, or record facing away from the noise — it's far more effective than any software filter.
5. Wear headphones. The single most common cause of echo on calls is your speakers feeding back into the mic. Headphones break that loop entirely and instantly.
6. Record ten seconds and actually listen back. The meter tells you the mic is alive; the playback tells you what people hear. Do this once before any interview or recording and you'll catch reverb, hum or harshness while there's still time to fix it.
