Have been looking for something simple to edit my MP3 music audios. Took me a long time to figure out this program as there were no instructions. Once I was able to do that found it very simple to use. The reason for the poor rating is the sound quality is sub-par with lots of noise and hiss when I saved my edited file as an MP3. When converting the edited audio into a WAV file the sound quality duplicated the quality of the edited file, but I do not play WAV files on my MP3 player. I would happily give this add on a 5 star rating if the MP3 sound quality duplicated the sound of the edited file.
