HOURLY CHIME ------------ Audible time signals at the full and half hour — three sounds to choose from: • Short beep — a clean single tone • F-G-C — two rising notes and a deep C • Thunder — a low rumble fitting the OKC theme Each interval (full / half hour) has its own independent sound selection. A quiet-hours window suppresses all chimes (default: 22:00 – 7:00, toggleable). Use the preview toggle in settings to audition any sound before enabling it.
