When you save the file i am assuming that you save it as a .mp3 file? Well anyway what i am saying is that maybe the audio codec that you are using to save the file from cool edit pro( like if your saving it as a .mp3 file there maybe an mp3 codec that you are using to compress the file into mp3 format) could something wrong with that ( audio codec you are using to save/compress files made in cool edit pro). Other then that i really gots no clue as to what is wrong.
Sorry
