What the sound simulator can tell you
This page generates audio in the browser when you choose a preview or type with sound enabled. The profiles demonstrate different synthetic timbres. They are not manufacturer recordings, matched replicas of named switches, or evidence about how a keyboard will sound before purchase.
A real keyboard's sound depends on the switches, case, plate, keycaps, stabilisers, mounting and room. Microphones, recordings, speakers and headphones also change the result. You cannot infer acoustic loudness, switch quality or a mechanical fault from this simulator.
Sound starts muted. Enable playback when you want it, then type or use the labelled preview buttons. Your browser may require a user action before its audio engine starts. The page does not request microphone access or record your keyboard.
The simulator varies the generated pitch by key code so you can compare the chosen effect on letter keys and larger keys. That variation is an illustration rather than an acoustic model calibrated to your keyboard.
A silent key is not proof of a dead switch. Check mute settings, browser audio permissions and focus. Use the ordinary keyboard tester for a visible record of events delivered to the page.
