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.

Streamripper ~ Record Shoutcast-compatible Streams


Streamripper was started sometime back in early 2000. Streamripper started as a way to separate tracks via Shoutcast’s title-streaming feature. This has now been expanded into a much more generic feature, where part of the program only tries to “hint” at where one track starts and another ends, thus allowing a mp3 decoding engine to scan for a silent mark, which is used to find an exact track separation.

Streamripper is now part of the FreeBSD standard distribution, mentioned in the Linux MP3 HOWTO, known to compile on many platforms such as Linux, Windows, FreeBSD, BeOS, OS/2. This is not surprising as portability was a constant consideration during development.

Streamripper allows you to download an entire station of music. Many of these mp3 radio stations only play certain genres, so you can now download an entire collection of goa/trance music, an entire collection of jazz, punk rock, whatever you want.
