Why can’t I see device names before granting permission?
Some browsers hide camera and microphone labels until you approve access. Start the relevant test, then the available device names should appear.

HelpFrequently asked questions
What should the microphone meter show?
The meter should rise when you speak or make a sound near the selected microphone. A flat meter can indicate the wrong input, muted hardware, or a system input-level setting.
How can I confirm that my voice sounds clear?
Starting the microphone automatically records a sample of up to 30 seconds. Stop and play it back to check intelligibility, volume, noise, and the selected input.
How do the speaker tests work?
Left and right tests send a short tone to one stereo channel. Stereo sends sound to both channels, helping you confirm placement and balance.
How do I know when the camera or microphone is active?
A persistent status strip remains visible while either device is active. Each panel also shows its active state and provides a Stop button.
Why can’t the tester switch speakers?
Speaker selection is available only in browsers that support output-device switching. You can still play the channel tests through the browser’s current output.
