You can also split Ogg Vorbis files with this tool.

A couple of other splitting options.

For raw/wav files, soundgrab is a simple console-based file splitter which 
lets you move around the file and select regions to be exported.  I've 
been using it for many many years for simple command-line-based file 
editing.

As the main website for it now seems to be down, you can get it from 
https://sourceforge.net/projects/soundgrab/

I usually use it in conjunction with sox and the quelcom tools (especially 
qwavjoin and qwavinfo to perform file editing.

Note that the quelcom tools also  have mp3 utils but I've never had much 
luck with them.  For mp3 I usually use madplay to find the split-points 
and mp3splt to do the splitting.

Finally ffmpeg should be able to slice up files without re-encoding but 
I've never actually used it for this so I don't know how good a job it 
does.
