Limiting amplitude of audio spikes

Is there recommended automated way to remove audio spikes,
based on limiting of amplitude of WAV/MP2 of audio record ?

I often do processing of DVB-T videos for personal archive purposes.
I use ProjectX to fix transmittion errors and process m2v and wav/mp2 files with MeGUI..

There are occasional spikes of maximum amplitude, some dozens ms in duration.
The problem with them is they ruin listener comfort.
They make squeezing noise and player often set volume temporarily weaker.

I fix it eventually by manual way in Audacity by setting silence there.

Is there an automated way, best by command line,
that either selectively limit amplitude under given values,
or fix/replace such a piece ?

I have not found in Audacity, or elsewhere, automated way, but I am not familiar with it audio processing so much.
