Mic, Speaker & Camera Test

This browser-based device test helps you confirm the three things people usually need before a call, recording session, interview, or livestream: microphone input, speaker output, and camera preview. Instead of opening separate apps, you can do a fast end-to-end check in one place. The page requests permission only when you start a specific test, and the captured streams remain local to your browser session.

The microphone panel shows whether a selected input device is detected and whether the signal level changes when you speak. That makes it useful for checking muted microphones, loose USB cables, weak wireless receivers, or a wrong system input setting. The speaker panel plays a short tone sequence so you can confirm that audio is reaching your headphones, laptop speakers, monitor speakers, or desktop output without needing a separate media file.

The camera panel opens a live preview so you can verify that the correct webcam is selected and that framing, exposure, focus, and motion look acceptable. This is especially useful if you switch between a built-in laptop camera and an external webcam or if you want to confirm that a privacy shutter is open. Because everything runs in the browser, the tool works well as a quick pre-meeting checklist for home offices, classrooms, support desks, and shared hot-desk setups.

While this page is convenient, it is not a full production diagnostics suite. It cannot replace studio monitoring tools, professional latency measurement, or vendor-specific camera utilities. It is best used for fast verification: Is the browser seeing the right devices? Is there a usable signal? Can you hear output? Does the camera look healthy enough for the next call or recording?

1. Use Refresh devices if you just plugged in a headset, webcam, USB dock, or microphone.
2. In the Audio input test section, choose the microphone you want to verify and click Start microphone test. Grant permission if your browser asks for it.
3. Speak at a normal distance and volume. The live level meter should move up and down. If it stays flat, check mute switches, gain controls, cable seating, and operating-system input settings.
4. In the Audio output test section, click Play speaker test. Listen for the short test tone and confirm the sound comes from the expected headset or speakers.
5. In the Video camera test section, choose the camera you need, then click Start camera test. Review the live preview for focus, framing, brightness, color, and smooth motion.
6. When you are done, stop the tests to release the microphone and camera so conferencing apps can use them immediately.

If labels are missing or a new device does not appear, refresh the device list again after permission is granted. Some browsers only reveal full device names after you approve access once.

• Checking your laptop before a Zoom, Google Meet, or Microsoft Teams call.
• Confirming that a new USB headset or webcam works after installation.
• Verifying which microphone is active when you have several devices connected.
• Testing a classroom, kiosk, studio corner, or hot-desk setup before users arrive.
• Helping family members or colleagues troubleshoot “no sound” or “camera not working” issues remotely.
• Making sure a privacy shutter, mute switch, or dock connection is not blocking the device you need.
