  2. Speak: Talk at a normal volume.
  3. Watch the Meter:
    • Green: Good signal. You are being heard clearly.
    • Red: Clipping. You are too loud/distorted.
    • No Movement: Your mic is muted or not selected.
  4. Listen Back: (Optional) Use the "Playback" feature to hear exactly what others hear.

Troubleshooting Common Issues

1. "Microphone Access Denied"

If you accidentally clicked "Block" or the test won't start:

  • Chrome: Click the lock icon 🔒 in the address bar > Reset permissions > Reload page.
  • MacOS: System Preferences > Security & Privacy > Privacy > Microphone > Allow your browser.
  • Windows: Settings > Privacy > Microphone > "Allow desktop apps to access your microphone."

2. Low Volume (Too Quiet)

  • Check Physical Switches: Some headsets have a mute switch or volume dial on the cord.
  • System Settings:
    • Windows: Right-click the speaker icon > Sounds > Recording > Properties > Levels > Boost Microphone.
    • Mac: System Preferences > Sound > Input > Adjust "Input Volume" slider.

3. Background Noise / Static

  • Ground Loop: If you hear a hum, unplug your laptop from the charger to see if it stops.
  • Gain Too High: If your "Boost" is maxed out, it amplifies static. Lower the gain and move the mic closer to your mouth instead.
  • Fan Noise: Directional mics (cardioid) help reject noise from behind. Point the back of the mic toward your computer fan.

Understanding Microphone Types

Built-in Mic (Laptop/Webcam)

  • Pros: Convenient, always there.
  • Cons: Often "tinny," picks up keyboard typing sounds and room echo.

USB Microphone (Blue Yeti, etc.)

  • Pros: Plug-and-play, drastic quality improvement.
  • Cons: Needs a USB port, can be bulky.

Headset Mic

  • Pros: Close to your mouth (good isolation), no echo.
  • Cons: "Telephone" sound quality compared to dedicated mics.

XLR Microphone (Professional)

  • Pros: Studio quality, low noise floor.
  • Cons: Expensive, requires an audio interface.

Frequently Asked Questions

Why do I hear an echo?

If you are testing without headphones, your microphone is picking up the sound from your speakers, creating a feedback loop. Always use headphones when testing playback.

Why does my voice sound weird?

You are used to hearing your voice "internally" through bone conduction in your skull, which adds bass. A recording captures only the air conduction, making your voice sound higher and thinner. This is how you actually sound to everyone else!

Can I test my webcam mic here?

Yes. If you have multiple mics (e.g., webcam + headset), use the dropdown menu in the tool (or your browser settings) to select the specific input you want to test.
