Ogg Vorbis

Ogg Vorbis is a new, patent-free, portable, open-source audio codec. Although still in beta, it is already capable of producing audio files similar in size and quality to MP3. CD-DA X-Tractor is committed to supporting this new format, and to that end I've created a BladeEnc-like DLL wrapper, vorb_enc.dll, for the Vorbis library. Vorb_enc.dll is included automatically with CD-DA X-Tractor distributions, so there is no need to download it separately. When new versions of the DLL are released, you may simply copy the new version over the older one.
