AirReceiver

AirReceiver is an AirPort Express emulator, i.e. it allows streaming audio from iTunes and iOS devices to a computer running AirReceiver.

It does so by implementing a RAOP/AirTunes2 server. This program is compatible with iTunes and iPhones/iPods. It implements not
only raw audio streaming but also the timing-related parts of RAOP/Airtunes2.
