The DVB01, commonly known as the "Daisy Buzzer," is a specialized audio testing device designed primarily for broadcast and engineering environments. Its main function is to generate a consistent, recognizable audio tone (typically a "daisy chain" or intermittent buzz) used to identify specific audio channels, test signal paths, and calibrate sound systems in live production or post-production studios.
