[linux-audio-user] edit mp3 files?

I have several MP3 files that I have to edit - there's a 1 or 2 minutes
intro on each file that needs to be removed. I want to do this in a way
that does not require re-encoding the file.
Essentially, I just want to remove a portion at the beginning of each
file and keep the rest untouched.

I tried Audacity first, but it seems like it's importing the file in
some internal format. If I chop off the head of the file, then I have to
export (re-encode) the rest, right?

Any other idea?
