I need some information regarding audio encoding. When I purchase a song from iTunes, it has been encoded with 128 AAC. If I want to burn it to CD, it gets encoded as an AIFF File. Obviously, when it gets reencoded to an AIFF, the sound quality does not improve seing as how the original song was only at 128 AAC, right? Why does the file jump in size from 4MB to 40MB then? What is creating the jump in file size seeing as there is no more information?

The AIFF file format is NOT compressed, while AAC files ARE compressed. Make sense?
