Magnus, please explain a bit more.  I'm not sure I follow this...

Hmmm.  If phase modulation is really a form of FM, then it seems
to follow from this that digital recording can't accurately
reproduce a frequency-modulated waveform.  But I'm sure that
isn't what you said.  What is the "harder to retrieve" form?
Are you talking about interpolating between samples?  There's
something I'm not understanding here.
