GitHub - openairplay/airplay2-receiver: AirPlay 2 Receiver - Python implementation

The article presents an experimental Python implementation of an AirPlay 2 receiver with some multi-room features. It includes support for HomeKit transient and non-transient pairing, FairPlay (v3) authentication and decryption, receiving REALTIME and BUFFERED audio streams, output latency compensation, RTCP handling, and decoding of various CODECs such as ALAC, AAC, OPUS, and PCM. The implementation is not fully comprehensive and lacks features like FairPlay v2 support, accurate audio sync, MFi Authentication (which requires MFi hardware module), PTP, removing all OS-specific code, Sender implementation, Raspbian package creation, DACP/+MRP? Support, and more. The article also provides instructions for running the receiver on various platforms like macOS Catalina, Windows, Raspberry Pi 4, and Debian systems.
