This program cuts and joins MP3 and WAV audio files at a very high level. The installation is extremely fast, and in seconds MP3 Cutter and Joiner launches on your desktop. The main window has two tabs, one for splitting and one for joining. The splitting tab asks you to select a file and destination folder, as well as to configure the splitting by either time or space. The joining tab lets you drop files onto a list and unify those files into one you name in a folder you specify. Both operations take little time and the performance is outstanding. The split files have no skips at the beginning or end, and the unified file is pop-free. The interface might look primitive, but the program's output is advanced.
