Which test do you need?
- People cannot hear you, or you sound bad: the mic test shows your level, warns about clipping and lets you hear a recording.
- Your camera is black, blurry or choppy: the webcam test shows the resolution and frame rate you really get.
- You have a video call coming up: the webcam and mic test checks both at once.
- You want to know how loud a room is: use the decibel meter.
