wtf is airplay2-receiver?

This project lets a computer act as an AirPlay 2 speaker, meaning you can stream audio to it from an iPhone, iPad, or Mac just like you would to an Apple TV or AirPods. It is written in Python and is designed as an experimental toolkit for understanding and testing how AirPlay 2 works under the hood. When you run the software, your computer announces itself on your local network as an available speaker. Once your Apple device sees it, the two go through a security handshake to verify the connection. After that, the software receives the audio stream from your phone, decodes it into playable sound, and plays it through your computer's speakers. The project handles the required pairing and authentication steps, and it can decode standard CD-quality audio formats like ALAC and AAC. The intended audience is developers, hobbyists, and tinkerers who want to experiment with the AirPlay 2 protocol rather than everyday users looking for a polished product. A practical use case would be someone who wants to turn a Raspberry Pi into a custom wireless speaker, or a developer who needs a testing environment to see how an iPhone communicates with an AirPlay 2 device. It can be run on a Raspberry Pi, macOS, or Windows. It is important to understand the tradeoffs here. The creator explicitly states this is not meant to be a fully functional, reliable speaker replacement. It currently lacks audio synchronization, which is what normally keeps multiple speakers playing in perfect time across different rooms. It also cannot connect to iTunes on Windows. If you need a robust, production-ready media receiver, this experimental toolbox will likely fall short.
