Comment(by mikus):

 Replying to [comment:13 Quozl]:
 > Mikus, aren't your additional Record activity concerns already covered
 by other tickets?
 Yes, they are.

 I think of myself as the sort of person who looks at the forest, rather
 than looking at the trees.  While attacking a complex situation may well
 require solving one problem at a time, my fear is that when that single
 problem has been tamed, the bean counters will say "enough" and "leave the
 rest be".

 The point of view that I often consider is "How useful is the XO ?"  When
 I see many comments devoted to "audio recording levels", I'm concerned
 about whether attention is being drawn away from "having video recording
 match the quality on the XO-1".  So I take the opportunity to say that
 solving "audio recording levels" helps, but does not by itself solve
 "making the XO useful".

 ----

 In your comment 11, you mention the "DC offset".  One of the things that
 in my mind makes the XO 'useful' is that one can vary the voltage (or is
 it the resistance?) presented at the microphone input of the XO-1, and
 thereby use the XO as an *instrument* for recording / remote sensing all
 sorts of physical phenomena (needing only a simple circuit plugged in to
 the microphone jack).  Again, I fear that measuring decibel levels
 addresses a particular tree, when there be many kinds of trees in the
 forest - for instance, think EKG.
