I have a few large MP3 files (some 7 hours, some 25 hours) and, sadly my player (car-hardware), does not scan well. So, if I listen up to the 3 hour point and I turn off my car, I must scan back to the 3 hour point (and this actually can take 10 minutes).
I am looking for a tool which can run on Windows, ideally free (but I would pay if necessary), with a graphical interface. The tool should take an MP3 file and a target length (say 10 minutes) and automatically split the one large MP3 into multiple smaller MP3.
I have tried Slice and found it to be quite unreliable (it regularly fails on the 25 hour MP3 file). I have tried Audacity but I have to manually mark each spot I want to split (a 25 hour audio will have 150 10-minue marks).
Mp3splt looks useful but it's command line. Is there a Windows GUI for it?
The GUI could be simple or complex. The goal is simply to avoid having to re-learn parameters every time my needs change by having a somewhat friendly UI.
Is there anything out there which will do this?
