Field notes
The interface combines presets such as 40, 100, 440, and 1k Hz with fine frequency steps down to 0.1 Hz. It also displays a tone visualizer with wave and spectrum views, plus note and octave controls. The page warns users to start at low volume and provides a safe-volume limit; those details make the controls more specific than a basic frequency dial.
