music Sharing

This is for my class and the difference on sharing. There sizes and there differences.

AAC 96 kbits its a better way of sharing more compressed and not so choppy.
MP3 128 kbits this is the most common share type.
AIFF 16 bits the biggest file size and its the apple version of sharing.

 The only real difference i heard was in the volume. AIFFs are much louder then MP3s. I really didn't hear any other difference. If i were to rip all my music i would rip them all as AAC. better quality but they take up a little more space.
