Shairport Sync ~ Unix AirPlay Player


Shairport Sync is an AirPlay audio player – it plays audio streamed from iTunes, iOS, Apple TV and macOS devices and AirPlay sources such as Quicktime Player and ForkedDaapd, among others.

Audio played by a Shairport Sync-powered device stays synchronised with the source and hence with similar devices playing the same source. In this way, synchronised multi-room audio is possible for players that support it, such as iTunes and the macOS Music app.

Shairport Sync runs on Linux, FreeBSD and OpenBSD. It does not support AirPlay video or photo streaming.

ALAC ~ Apple Lossless Audio Codec


The Apple Lossless Audio Codec (ALAC) is an audio codec developed by Apple and supported on iPhone, iPad, most iPods, Mac and iTunes. ALAC is a data compression method which reduces the size of audio files with no loss of information. A decoded ALAC stream is bit-for-bit identical to the original uncompressed audio file.

The Apple Lossless Audio Codec project contains the sources for the ALAC encoder and decoder. Also included is an example command line utility, called alacconvert, to read and write audio data to/from Core Audio Format (CAF) and WAVE files. A description of a ‘magic cookie’ for use with files based on the ISO base media file format (e.g. MP4 and M4A) is included as well.

beets ~ The Music Geek’s Media Organizer


The purpose of beets is to get your music collection right once and for all. It catalogs your collection, automatically improving its metadata as it goes using the MusicBrainz database. Then it provides a bouquet of tools for manipulating and accessing your music.

Because beets is designed as a library, it can do almost anything you can imagine for your music collection. Via plugins, beets becomes a panacea:

  • Fetch or calculate all the metadata you could possibly need: album art, lyrics, genres, tempos, ReplayGain levels, or acoustic fingerprints.
  • Get metadata from MusicBrainz, Discogs or Beatport. Or guess metadata using songs’ filenames or their acoustic fingerprints.
  • Transcode audio to any format you like.
  • Check your library for duplicate tracks and albums or for albums that are missing tracks
  • Browse your music library graphically through a Web browser and play it in any browser that supports HTML5 Audio and lots more.
