      True enough. A condensor mic is basically a capacitor, with one plate of
      the capacitor (effectively) connected to a plate that catches audio sound
      vibrations, which causes that plate to vibrate, which causes a variation
      of the capacity between the plates of the condensor -- the space between
      the plates varies the overall capacitance.

      Add some batteries, and that variable capacitor is varying the fraction of
      a substantial voltage available to the output. So from a small-amplitude
      input, you're recording a fairly-large-volume, filtered DC output that
      reproduces your audio.

      But you need the voltage to make that small volume of varying capacity
      into a large volume, varying voltage.

      It was 1 Jan 2008, when Richard Amirault commented:
