I downloaded 'vorbis-tools' from the Ubuntu repository. What a powerful little program. I might post examples once I start using it more. This is a command line program that I use on the linux OS. You can learn more about each of these programs by typing 'man [program]' on the command line; example 'man oggenc'
vorbis-tools contains oggenc (an encoder), ogg123 (a playback tool),
ogginfo (displays ogg information), oggdec (decodes ogg files), vcut
(ogg file splitter), and vorbiscomment (ogg comment editor).
ogg123 can play both Ogg Vorbis and FLAC audio streams
