Normally, I would too.  However, audacity is allowing me to cut out
chunks of "silence" between words, and "repair" overly high spikes of
sound that I can see on the screen in the wave pattern.  I can also
remove pops and clicks, and generally clean up the sound byte.  I
kinda like this GUI.  It's easy, intuitive, and imports/exports all
the formats I need and more (well, OK, not GSM, but all the rest).
