Hi Will,
You're right, normalize will boost everything. On second thought, I
think you'll need to use a combination of compressor/limiter/
normalization filters. A compressor would compress the difference
between the loudest and softest parts of your recording (dynamic
range). And a limiter would place a ceiling on audio spikes above a
certain threshold. Audacity has a compressor, that will also allow
you to set a threshold, as well as adjust the attack time, which is
how much time ensues before the compressor kicks in. It also
normalizes too.
Good luck,
Kimo
