Webcam and Mic Test: Camera and Microphone Together
Test your webcam and microphone on one page before a video call. See the live preview, delivered resolution, measured frame rate, microphone level and waveform, then record and play back five seconds of audio and video.
Webcam and Mic Test: Camera and Microphone Together: Shows your live camera image and microphone input together. It measures delivered camera frames and digital sound level, and records a five-second audio and video clip when both devices and browser recording are available. The checklist confirms a running preview and detected sound; you judge echo by listening. It does not test network quality or guarantee that another call app will work. Runs 100% locally in your browser with zero server file uploads.

Test your camera and microphone together before a video call. Nothing is uploaded. Recording starts only when you press Record.
Microphone
-60.0 dBFS
Speak normally. A moving meter shows that sound is reaching the browser; it does not measure room loudness.
- Camera OK: Not checked
- Mic picking up sound: Not checked
- No echo heard: Not checked
Echo cannot be detected reliably here. Wear headphones for playback, then confirm whether your clip sounds clear. This test does not check your call connection.
Audio and video recording is unavailable in this browser. Try another browser; the live test still works.
Both camera and microphone must be running to record audio and video together.

Frequently asked questions
Can I test just one available device?
Yes. Start test first requests both camera and microphone. If that request fails, each is tried separately so an available and permitted device can still work. Recording audio and video together requires both.
Why does the frame rate differ from my camera specification?
This page counts frames delivered to the preview, rather than promising the camera's maximum rate. Lighting, browser constraints and machine load can affect it. The resolution is the actual video size.
How do I check for echo?
Record normal speech, then listen with headphones and confirm whether you hear echo. No sound is sent to your speakers during the live test. Your live mic pauses while the clip plays. This is a listening check, not automatic echo detection.
Why is recording unavailable?
The browser must support a recording format that includes audio and video. If it does not, use the live preview and meter or try another browser. Recording is also disabled until both devices are running.
