AmpliPi™ is a multi room/zone home audio controller and amplifier made for whole house audio systems with many zones. It can play up to 4 simultaneous audio sources, each of which can be selected from either its analog RCA input or any supported digital stream (Pandora, Spotify, AirPlay, etc). Each source can be routed to one or more zones, all of which are configurable in real-time using the self-hosted AmpliPi Web App or its underlying REST API. It is expandable up to 36 zones using AmpliPi Zone Expanders.The system is self-hosted on the Raspberry Pi and is privacy-centric. By design, AmpliPi doesn’t listen to you or spy on you — it just plays your audio! The way it should be. An internet connection is only needed for some external streaming sources, such as Pandora. The Python application running on the Pi hosts a mobile-friendly website and REST API used to control the system. The website is built on top of the REST API.
