MeterSee, a browser-based hardware diagnostic bench

Why it surfaced

Its microphone bench does more than show a moving meter: it records peak level, noise floor, and clip count, then helps separate hardware trouble from browser or operating-system trouble. The site also makes a clear privacy claim—the audio stays in the browser—and carefully warns that its dBFS readings are estimates, not acoustic measurements.

MeterSee tests microphones, webcams, speakers, displays, and other peripherals without installation.
