Microphone guide

How to test your microphone online

Check that your browser can hear the correct microphone and review practical voice-quality results before a call or recording.

Your raw microphone audio stays on this device. MicTestLab analyzes the live signal in your browser.

Prepare your microphone

Connect the microphone or headset before you open the test.
Close other apps that may be using the microphone.
Use a quiet room and place the microphone a comfortable distance from your mouth.

Run the microphone test

Open the Microphone test and select the input that you want to check.
Select Start Audio Test, allow microphone access, and speak naturally for several seconds.
Watch the waveform and review the input name, sample rate, latency, and voice clarity result.

Common microphone problems

The browser cannot hear you

Check the browser permission, the operating system input setting, the hardware mute switch, and the selected input.

Your voice clips or sounds distorted

Lower the input gain or move farther from the microphone. A waveform that reaches its limit can indicate clipping.

Your voice sounds quiet or noisy

Move closer, reduce room noise, and check that the microphone opening is not blocked.

Understand the results

Input and sample rate

The active input confirms which device the browser uses. Sample rate shows how often the browser captures the signal.

Latency

Base and output latency are browser estimates. The optional sound ping also depends on your speakers, room, and microphone.

Voice clarity

The clarity score is a practical browser estimate based on the live signal. It is not a calibrated laboratory measurement.

Webcam guide

How to test your webcam online

Check the correct camera, preview quality, lighting, focus, frame rate, and supported resolutions before a video call.

Your raw webcam video stays on this device. MicTestLab analyzes preview frames in your browser.

Prepare your webcam

Connect the camera and remove any privacy cover before you open the test.
Close other apps that may be using the camera.
Face a soft light and place the camera near eye level.

Run the webcam test

Open the Webcam test and select the camera that you want to check.
Select Start Camera Test, allow camera access, and wait for the preview to settle.
Review the preview, active resolution, frame rate, lighting, sharpness, and optional resolution scan.

Common webcam problems

The camera does not start

Check browser and operating system permissions, close other camera apps, and confirm that the privacy cover is open.

The image is dark or washed out

Add soft light in front of you and avoid a bright window or lamp directly behind you.

The image is blurry or unstable

Clean the lens, hold the camera steady, improve the light, and check whether autofocus has settled.

Understand the results

Resolution

Active resolution is the size of the current browser video stream. The scan checks which common sizes the camera accepts.

Frame rate

FPS shows how many video frames arrive each second. Low or unstable FPS can follow poor light, heavy system load, or a busy connection.

Lighting and sharpness

These are practical browser estimates from preview frames. They are not calibrated camera certification.
