im just playing around with itunes at the moment (part of my dissertation research) and i see it will convert my current files to lossless audio files if i wish.

What i wondered was, assuming i have mp3's on here, what would i gain from changing their format to lossless. Surely the information that is removed during the mp3 encoding to give it its small size is gone and so converting an mp3 to a better form wouldnt actually give you anything back.

Im a wrong in this assumption?

No, you are not.

It is the same as converting an MP3 to WAV - no better quality, just a bigger filesize.

The Apple Lossless files will sound identical to the original mp3, and the file size will be much bigger. If you make new lossy files from these apple lossless files, you are in effect, transcoding from mp3 and there will be a quality loss. So you gain nothing in quality, and you add more filesize for naught.
