Mic Checker Online

Mic Checker Online: the full method

1. Pick the right input

   Open the device list at the top of the console. Every microphone the system can see is listed by name. Choose the one you actually intend to use — the default is often a webcam or a virtual cable.

2. Press Start test and allow access

   The browser shows a permission prompt. Choose Allow. Nothing is recorded until you press Record, and even then the audio stays on your machine.

3. Speak at your normal distance

   Say a full sentence at conversational volume, sitting where you normally sit. The meter should swing between -24 dB and -6 dB. A flat meter means no signal is arriving.

4. Check the waveform for damage

   Open the Waveform panel. A healthy voice looks like rounded peaks with space above and below. Flat tops touching the edges mean the signal is clipping and words will sound crunchy.

5. Record and play it back

   Levels can look perfect while the audio sounds terrible. Record five seconds, play it back, and listen for hiss, hum, echo and keyboard noise.

6. Read the report

   The Report panel names the device, its sample rate and channel count, whether echo cancellation and auto gain are active, and gives a plain verdict you can copy into a support ticket.

If the meter does not move

• Something else has the microphoneZoom, Teams, Discord, OBS and Camera apps can hold an input exclusively. Quit them completely, including from the system tray, and try again.
• A hardware mute is engagedMany headsets mute when the boom is rotated up, and most USB mics have a mute button that stays lit. Check the physical control before touching any software.
• The operating system muted the inputOpen your sound settings and confirm the input volume is not at zero and the device is not disabled. A muted input produces a perfectly flat meter with no error message.
• The browser was never allowedClick the padlock or slider icon at the left of the address bar, set Microphone to Allow, then reload the page. A blocked prompt never appears twice on its own.

The order to change things in

Position first, gain second, processing last. Moving from 60 cm to 20 cm raises your voice by roughly 10 dB while leaving the room noise exactly where it was — an improvement no software setting can match.

Gain comes next because it lifts your voice and the room together; it fixes quiet, never unclear. Processing comes last because every effect works on whatever the first two decisions produced. Applied to a good signal it is subtle and useful. Applied to a distant voice in a noisy room it has to remove so much that it damages the voice too.
