The chime is associated with Gamepad Tester Lite, an app used to check buttons, sticks and triggers on a connected gamepad. Its notification sound was made to be short and easy to recognise during testing, which is also why it works well outside the app as a generic system alert. On soundboards it is listed alongside other brief notification and interface sounds, and creators reuse it when they need a clean, non-distracting cue for a connection, confirmation or completed action in a video.
