Hi all, Quick question: I've been having some trouble with iTunes Match (long story, purchased aac files don't seem to Match OR upload, just sit in my library 'waiting'), and the only way I've found that makes iTunes upload them is to convert to Apple Lossless (using iTunes) and then add to iCloud. My question is, in the following process: Purchased AAC file (256kbit) > Apple Lossless > AAC (Match automatically transcodes the ALAC songs back down to 256kbit to upload the to the cloud), how much loss of quality is there? As far as I understand it, the ALAC should be an exact copy of the Purchased AAC (no loss of quality), right? (I realise songs purchased from the official store are already lossy at 256kbit, but can live with that) However, when that lossless file gets converted back to 256kbit during the upload process, are there additional losses incurred? As in, is the end file that I stream from iCloud identical to the Purchased AAC I started with? Common sense tells me that they aren't, as the file *has* been re-converted, but as it's essentially the same format (not aac to mp3, so the compression technically uses the same algorithm (does it?), I am holding out hope that maybe they are? Any light you can shed on the subject would be MUCH appreciated!
