What is Bars and Tone?
Bars and Tone is a combination of color bars and an audio tone used in video and broadcast production for calibration and testing purposes. It serves as a reference signal to ensure proper alignment of video colors and audio levels across different devices and platforms. Typically placed at the beginning of a video or broadcast, Bars and Tone helps technicians confirm that the footage is being displayed and heard accurately before the main content plays.
