Digital audio and video

Digital audio and video are formats that store sound and visual information as a series of tiny numerical values, called samples, which represent the original signals precisely. This process allows for easy editing, copying, and transmission without loss of quality. For audio, microphones convert sound into digital data, while speakers convert it back to sound. For video, cameras capture images frame-by-frame, converting scenes into digital images that are played in rapid succession to create motion. Overall, digital media enables high-quality, flexible, and durable content suitable for modern communication and entertainment.
