ffmpeg can do this.
Assuming it's the first 5 seconds (as an example), syntax would be
ffmpeg -i longerfile.mp3 -ss 5 -t 300 newfile.mp3
on a 300 second mp3. In other words, the -ss is the start time and the
-t is the duration of time you want to keep. So, that will give you all
but the first 5 seconds of the file.
You would have to know the duration of each file.
You might also want to use the -sameq argument as well, which will keep
the new file at the same quality as the old one.
ffmpeg -i longerfile.mp3 -ss 5 -t 300 -sameq newfile.mp3

Cordelia: We were just discussing whether or not we should
offer to pay Gunn.
Angel: No you weren't.
Wesley: Well, our discussions tend to go about 3 minutes, then it's
strictly name calling and hair pulling.
