Pulse Code Modulation means 'sample values collected at a fixed
discrete interval'.  PCM can be 32 bit, float, nonlinear (like
mu-law), etc.  What you describe is PCM, just not 16 bit to start.

If you save your data as a 32 bit WAV, Vobis will encode that just
fine.  As a note, though, that might require that vorbis-tools
understand WAVEEXTENSIBLE format, which is in the SVN version of
oggenc, but hasn't been released quite yet.
