but I think mp3splt will only devide a file which was wrapped.
mp3splt works on any file and can divide a file based on described split-points (such as the metadata file generated by mp3join), based on time intervals (every 3 minutes becomes a new mp3) or based on silence-thresholds (I tried that, but had less luck because many podcasts include filler or background music that obscure the airtime silence).
The main reason I use mp3splt/mp3join instead of sox is that sox transcodes the file(s) degrading the quality a little at each split/join; while mp3splt/mp3join just copy the raw data-frames into the new file without transcoding. If you have uncompressed audio (.flac, .wav, .au, etc) then using sox could work well too.
I formerly used mp3splt for all of my podcasts because my old mp3 player (an RCA Opal piece of junk) would only remember the track of a podcast (not where in the track) you were if you turned it off, and the fast-forward button worked in such small increments that it was a pain. So I use mp3splt to chop up my podcasts into 3-minute segments so I only ever had to fast-forward or rewind by about 1.5 minutes instead of sitting there waiting to fast-forward through 40 minutes of an hour show. However I now have a new mp3 player which isn't as brain-dead, so I don't have to slice up my podcasts.
