loud and clear

loud and clear idiom
Easily audible and understandable. For example, They told us, loud and clear, what to do in an emergency, or You needn't repeat it—I hear you loud and clear. This expression gained currency in the military during World War II to acknowledge radio messages ( I read you loud and clear) although it originated in the late 1800s.
