How can I batch trim 2 seconds from a bunch of .wav files?

I have 300 .wav files that include the 2 second pause at the end.  (I'm still not sure how I messed that up).

Is there an easy way I can trim that off?  Preferably with a command line batch utility (I'm on Win XP).

Does the .wav header need to be adjusted as well?

My only other option is to re-extract all the discs.  Ouch.

Audacity might be able to batch this.

I believe Audacity handles this automatically.

Did you somehow add the pauses, or are they on the CDs? In the latter case, I'd leave them in (definitely if you have cue sheets), but it's obviously your call.

WavTrim is a GUI tool and is able to delete silence at beginning/end of a WAV file.

For batch processing I would use the command line tool SoX. It has a command called "silence" which configurably "[r]emoves silence from the beginning or end of a sound file."

Thanks, WavTrim did the trick.  And it has the benefit of being able to truncate the files in place which takes an instant.
