From the developer:
"MP3 TrackMaker is an MP3 audio editing utility that is used to split up an MP3 into multiple files (tracks) or to join MP3s into one larger MP3 (mix). This utility is perfect for dividing up those long radio shows or mixes that you have. MP3 TrackMaker is great for those burned CDs: now you can avoid having one 70 minute track and instead create your own tracks. Joining MP3s into a single mix allows for easy transportation of your audio without the hassle of worrying about multiple files.
"New in version 1.5! Now adds support for individual artist and title properties for each track for use when outputting to files. With CUE files containing track information, it is easier than ever to split up your favorite MP3s."
