Every day there are more MP3 players, apart from the traditional devices now there are digital cameras, PDA´s, Pocket PCs and even mobile phones.
The problem is that these devices, in general because of a lack of memory, have a limit to the number of songs they can store. Thus a tool like DietMP3 4.03.00 becomes useful, as it compresses your MP3 files, letting you add a larger number of songs to your player without having to spend money on a larger memory.
The program works on the MP3 you indicate and gives you a collection of much reduced size files (between 30% and 70%) adjusting the various sound parameters.
