Camera & microphone

Camera and mic checks.

Choose a detailed microphone test, a camera preview, or a combined check before a meeting. The combined tool brings camera, microphone and playback results into one summary. All three run on your device; none connects to a remote caller or shows what that caller receives.

• Call check

  Microphone Test

  View the waveform, RMS level and sample peak, count clipping windows, or record a clip for local playback. Compare speech with the noise floor.

• Call check

  Webcam Test

  Preview your camera with resolution and frame-rate readings. Mirror the image or freeze a frame to inspect focus.

• Call check

  Video Call Test

  Check both devices and measure speaker-to-microphone bleed. The readiness summary also requires your own confirmations.
