Vorbis is lossy audio compression format.  It takes PCM data (at least
oggenc,
the encoder, does) and crunches it down by eliminating unnecessary audio
components and doing other such magic.

I think you are looking for sox, an audio conversion program which
(according
to its manual page) can read and write PCM and mu-law wav files.
