aac is the best quality but takes up a lot of room about 300 megs per cd. mp3 is a lesser quality but takes up far less room.
my bad I was thinking apple losssless.um WRONG at every level......
AAC is better quality for the file size
However, it sounds as if your library is already mp3 so keep it that way as any encoding is as good as the source
all other imports though, use aac
haha then you would be correct!my bad I was thinking apple losssless.
