Direct answer
A whole-home audio system distributes music and other audio to multiple rooms through coordinated sources, amplifiers, controls, and speakers. Each room or outdoor area becomes a zone, so occupants can select content, adjust volume, and group rooms without operating an independent stereo in every space. Equipment may be centralized in a rack or distributed around the home; wired, wireless, and hybrid designs are all possible.
The defining benefit is coordinated control. One source can play in every entertaining area, while bedrooms play different content at independent volumes. The design must account for simultaneous streams, amplifier channels, speaker loads, network reliability, account permissions, and intuitive controls. Camelback's distributed-audio page describes rooms throughout the home plus outdoor and landscape speakers.
