Sorry, I should have been more explicit  :<  (I keep

This is a one-shot deal.  I need to build some voices
for festival (et al.).  So, with the possible
exception
of screwing something up on iteration N, it's just
a single pass through the digitizer and then discard
the audio *and* the equipment to digitize it!  :>

Yes, I've been cautioned that a head mounted mic is
the "Right Way" to go.

I still suspect recording to *tape* may be a win
as I can then re-digitize if I decide I want to
change the sampling rate (without having to
resort to "resampling" the digitized data)
