Dead Air

Dead Air is complete, unplanned silence on the transmitter: no content, no music, no voice, no ambient sound. It is the most visible possible failure of a broadcast operation because listeners immediately assume the station has gone off the air, switch to a competitor, and often do not return. Dead air of more than a few seconds is actionable in most markets and can trigger regulatory scrutiny.

Modern automation systems guard aggressively against dead air: silence-detection circuits monitor the audio path and trigger emergency fallbacks: pre-recorded music libraries, loop-tape fillers, backup satellite feeds: within seconds of detecting silence. The goal is for listeners never to experience dead air even when the primary programme source fails completely. Station engineering culture treats silence-detection quality as non-negotiable operational infrastructure.
