There’s now a plug-in that allows Mac’s iTunes to play Ogg Vorbis, the open-source audio codec. I started encoding the radio show in Ogg Vorbis back in July. It provides good broadcast-quality sound with slightly smaller files than mp3. I also see Ogg Vorbis as a little more “future-proof,” from the standpoint that it’s open source nature prevents it from being closed off and made inaccessible by a corporate owner. And, of course, I’m a supporter of free software. (via Slashdot).
