You can do it with Nero:
start compiling an 'Audio CD' in Nero. Load your long track into the compilation window, highlight it, and right click. Select 'Properties' then the 'Indexes, Limits, Split' tab. It appears that you can just set indexes to do what you want, OR split if you wish. Pretty cool.

In Nero's help, search :'Indexes, Limits, Split' for more help.
