Ogg Vorbis is a <buzzwords>non-proprietary,
royalty-free, fully variable bitrate, high
quality</buzzwords> (lossy) audio compression
format, similar to the popular MP3 but better in many respects (and
not patent-impaired); it can be used for many purposes, including
Internet audio streaming. For various reasons (some ideological, some
technical), I cannot use RealAudio streams, or even less Windows Media
Format. I wish content providers and Internet radios finally finally
understood that Ogg Vorbis is better than these in every
respect (and just as widely supported!) and got around to using it for
streaming.
Unfortunately, Ogg Vorbis streaming Internet radios are still very few. The BBC attempted some Ogg Vorbis streaming, but it didn't last. Radio France is now doing it, but their service provider is hopelessly incompetent and the streams' quality is Zeus-awful. Besides these, a few specimens such as University Radio Nottingham or Ona Mallorca (in Catalan) provide an Ogg Vorbis stream of good quality. Recently I also discovered WCPE which broadcasts classical music round-the-clock and has an Ogg Vorbis stream.
But I really wish I could find a non-musical radio (I mean, news, talk, chat, debates, whatever) in English that broadcasts in Ogg Vorbis. The BBC would have been wonderful: I really need to listen to BBC English. It's such a shame they shut these Ogg streams down.
