    MP3/AAC Question?

    Which one of these takes up less space?

    And If u convert from MP3 to AAC using itunes "convert to AAC" feature, does it make it protected?

    I just experimented with this, using iTunes for both rips.

    The Ataris' "In This Diary" from a tour sampler was my dummy file...

    AAC at 128 kbps is like sound quality to an MP3 at 192 kbps.

    AAC, 128 kbps: 3.6 MB
    MP3, 192 kbps: 5.4 MB

    MP3, 128 kbps: 3.6 MB

    So, if you encode both at 128 kbps, you are going to get a very like-sized file, but probably going to suffer noticeable quality loss if you go with MP3.

    As for your protected question, only iTMS files are in M4P format. Normal AAC-encoded files are M4A.
