Electronic sound reproduction, also known as AUDIO, is the process of capturing, storing, and reproducing sound using electronic devices. It involves the use of microphones to capture sound waves, amplifiers to increase the volume of the sound, and speakers to reproduce the sound. AUDIO technology has been used in various forms since the early 20th century, and has become increasingly sophisticated over time. Today, it is used in a variety of applications, from recording music to broadcasting radio and television programs.
