Description:
emulates an AirPort Express (shared library)
This program emulates an AirPort Express for the purpose of streaming music from iTunes and compatible iPods. It implements a server for the Apple RAOP protocol. ShairPort does not support AirPlay v2 (video and photo streaming). It supports multiple simultaneous streams, if your audio output chain (as detected by libao) does so. . This package installs the shared library.
