I agree with Fons about editing out the peaks, as possible. Make
sure your start/end cut points are at zero crossings and the
crossfade will be smooth.

If the big peak contains sounds you need to keep, then you can
select the offending section, again with start/end at zero
crossings, and just reduce the gain of that section.

Usually I attend to the very worst abnormalities individually.
After that I apply a fast look ahead limiter to deal with the
remaining peaks, if needed. Following that I might compress the
track, if needed, or I might try to level the volume, if needed.
I use Audacity for all of this.

Good luck....
