▶ Open Mic TesterWhy Test Your Microphone?
Nothing is worse than joining a meeting to find your mic isn't working. Test your audio input before calls, recordings, or gaming. Common reasons to test:
- Before video calls — Verify Zoom, Teams, or Meet will pick up your voice
- New hardware — Ensure a new headset or mic works correctly
- Troubleshooting — Determine if problems are hardware or software
- Buying used laptops — Confirm built-in mic is functional
- Recording setup — Check input levels before podcasts or voice recordings
What Our Test Shows
You'll see a real-time audio waveform that moves when your mic picks up sound:
- Mic working — Waveform reacts when you speak
- Input level — How loud or quiet the signal is
- Background noise — Visible even when silent
- Sensitivity — How well the mic picks up quiet sounds
💡 Privacy Guaranteed
Audio is never recorded or transmitted. Processing happens entirely in your browser. No data leaves your device.
Troubleshooting
Mic not detected
Check connections, try different USB ports, verify browser permissions (lock icon in address bar), and ensure no other app is using the mic exclusively.
Volume too low
On Windows: Settings → Sound → Input → increase volume. On Mac: System Preferences → Sound → Input → adjust slider. Some USB mics have hardware volume dials.
Echo or feedback
Use headphones during testing, or mute speakers. Echo happens when speakers play back mic input.
FAQ
Works with Bluetooth earbuds?
Yes — AirPods, Galaxy Buds, and all Bluetooth devices work when connected and set as default input.
Why does my mic sound different in recordings?
Recording apps apply noise reduction, compression, and EQ. Our test shows raw mic input, which naturally sounds different.
