Television Color Bars Sound Effect

This is the steady, high-pitched tone that plays alongside the classic TV color bars test pattern, a single continuous sine wave with no variation or fade. Its clean, piercing character instantly signals a broadcast standby screen, a channel off the air, or the moment before a program begins. Editors reach for it to suggest retro television, signal interruptions, or an unsettling technical pause. The clip loops cleanly and sits comfortably under visuals of the SMPTE bar pattern.
