If you're using ALSA it should be possible to install a compressor
plugin to "normalize" the audio. Note that this isn't true
normalization, it simply makes all audio the about the same volume. I
haven't set this up myself, maybe somebody else on here has, but I
might look into it sometime in the near future as it seems like every
recording is the opposite volume of the last.
