What it is

This program emulates an AirPort Express for the purpose of streaming music from iTunes and compatible iPods and iPhones. It implements a server for the Apple RAOP protocol. ShairPort does not support AirPlay v2 (video and photo streaming).

Build Requirements


  • OpenSSL


  • libao
  • PulseAudio
  • avahi

Debian/Raspbian users can get the basics with apt-get install libssl-dev libavahi-client-dev libasound2-dev

Runtime Requirements

You must be running an mDNS (Bonjour) daemon. On a Mac, this will be running already. Otherwise, you must be running avahi-daemon or Howl. As an alternative, you may use the tinysvcmdns backend, which embeds a lightweight mDNS daemon. It is, however, way less robust than bonjour or avahi. Check the [mDNS Backends] section for more information.

How to get started

./shairport -a 'My Shairport Name'

The triangle-in-rectangle AirTunes (now AirPlay) logo will appear in the iTunes status bar of any machine on the network, or on iPod/iPhone play controls screen. Choose your access point name to start streaming to the ShairPort instance.

Audio Outputs

Shairport supports different audio backends. For a list of available backends and their options, run shairport -h. Note that options are supplied to backends at the end of the commandline, separated by --, for example:

shairport -o ao -- -d mydriver -o setting=thing

mDNS Backends

Shairport uses mDNS to advertise the service. Multiple backends are available to perform the task. For a list of available backends, run shairport -h. The backends prefixed by 'external' rely on external programs that should be present in your path. By default, shairport will try all backends, in the order they are listed by shairport -h, until one works. You can force the use of a specific backend using shairport -m tinysvcmdns for example.


Big thanks to David Hammerton for releasing an ALAC decoder, which is reproduced here in full. Thanks to everyone who has worked to reverse engineer the RAOP protocol - after finding the keys, everything else was pretty much trivial. Thanks also to Apple for obfuscating the private key in the ROM image, using a scheme that made the deobfuscation code itself stand out like a flare. Thanks to Ten Thousand Free Men and their Families for having a computer and stuff. Thanks to wtbw.
