wv2ogg is a tool that uses wvunpack, oggenc, and vorbiscomment to encode wavpack files to Ogg Vorbis files. The quality setting that will be used for encoding the Vorbis files can be set when running wv2ogg. It will also transfer all tags and replaygain information from the wavpack files to the Ogg Vorbis files by default. wv2ogg was written because no other software that would do this existed for Linux.
dudl is a collection of tools to grab, encode, and rename MP3 files, archive them, and maintain a database of all files. On top of this runs the dudld Jukebox daemon that plays your files through gstreamer. dudld's strengths are the powerful tag based filters, the capability to cope with very large collections, and the network protocol to control its operation. There is a full featured command-line client, a minimalistic GTK client, and a lirc client. Writing new clients should be easy with the supplied client libraries.
