rosalindavenue said:My understanding is that a track is converted to uncompressed AIFF when it is burned to CD-- however, the original song lost a lot of "bits" in being compressed to AAC-- and those original bits are not reinstated when the AAC is blown back up to AIFF. So the AIFF is like a swiss cheese copy. I think the re-burned track does retain the original quality of the DRM'd AAC, but that quality is not the quality of the real full uncompressed track.
That's correct. It's like saving a digital photo as a compressed jpeg - you can reopen the photo and save it as an uncompressed tiff, but all of the compression artifacts will remain. If you open the tiff and save it again as a jpeg you are doubling the compression artifacts. The rule pretty much applies to any digital media file - movie, sound, picture. If compression is applied, you aren't ever getting the original quality back.
