An collection of documents about icecast/shoutcast streaming.

• icy_meta.md contains the basics of metadata within the stream. The document where I got this information from (http://www.smackfu.com/stuff/programming/shoutcast.html) is not available any more.
• spec.md is a copy of this gist https://gist.github.com/ePirat/adc3b8ba00d85b7e3870 just to prevent the informtation from disappearing. You may find the discussion beneath the original gist interresting as well.
• icy.rb is the most simple icy metadata parser written in Ruby.
• Some information can be found here: https://cast.readme.io/docs/icy
