My completed work sounds great in Magix program (14 or 16), but when I export it to mp3 format, the sound quality is lost.  I then take the mp3 and use the stereo processor to restore it to the sound I want, but when I save it and export it again as an mp3,  the specific quality of sound is lost again.  Hmmm.  How do I retain the sound quality I find in the program and carry it over to an mp3?
