# Whole House Audio System We're designing a completely open hardware and open source solution for whole-house audio distribution. The key hardware component is a board containing a USB audio interface and stereo 50 watt class-D audio amplifier. A set of these boards, one per "zone", get wired to speakers in the various rooms. A Linux system runs software that controls audio stream sources, maps them to the various zones, and volume controls the zones .. all controllable from a web browser or Android application. More details will be posted soon!
