Any help will be much appreciated. > Although technically you can convert it to an AIFF file, you won't get the original file. MP3 uses a "lossy" compression algorithm, and basically depends on eliminating certain frequencies that supposedly are not perceived by the majority of people, so by its very nature, the mp3 file is a lower quality version of the original AIFF. If you don't care about this and only need the file in an AIFF format, just use iTunes to convert it. dZ.
