How to use the Keyboard Sound Test
How do I capture a keyboard sound sample?
Enable the microphone and type a few lines at your usual pace. Stop the microphone to review the observed metrics. Audio is analyzed in this browser and only the numerical readings and labels can be saved or exported.
What do thock and clack mean here?
These are informal terms for deeper and brighter sound. The analyzer compares energy in low and high frequency bands. Match microphone position, room noise, typing force and desk setup when comparing keyboards.
What does the switch chatter check measure?
Select a key, choose Run 100, then press and release that key 100 times. The tool flags consecutive presses inside the selected threshold. Repeat the check if you see short intervals you did not expect.
