Ogg Vorbis audio format as a replacement for mp3: "Vorbis was started following a September 1998 letter from Fraunhofer Gesellschaft announcing plans to charge licensing fees for the MP3 format.... Vorbis is considered to be one of the highest quality audio codecs in use today. For many applications, Vorbis has clear advantages over other modern codecs, in that it is patent-free, and therefore free to use, implement, or modify as one sees fit, yet produces smaller files than most other codecs at equivalent quality."
