WavTrim is an automatic WAV file cleaner.
WavTrim is useful:

When you extract a track from an Audio-CD (CD ripping).
Before making MP3s (MP3 encoding).
Before making Audio-CDs (CD burning).

WavTrim was originally created to help extract audio tracks from CDs.
Audio-CD song extraction is not very accurate (you easily get a little bit of the end of the previous track, or of the beginning of the next track). It is possible to trim each track by hand (using a regular WAV editor software), but that's tedious. So WavTrim first purpose was to scan and clean WAV files, removing silence and any leftover of another track.

WavTrim grew up as a multi-purpose WAV cleaner:

Volume normalization (i.e. changing the volume to use complete 16-bits dynamic - that can help to get tracks from different sources sound similar)
Batch mode (process several WAV files at once)
and more... Just try it!
