iTunes4 and re-ripping to AAC Apps
Don't know if any of you guys noticed this yet. I just found that iTunes4 has a cool way of re-ripping your music using the AAC format. Let's say you have the Beck Album "Sea Change." You have all the songs encoded at 160 kbps MP3 with star ratings, play counts, playlists referencing the songs, genres attached etc. etc. and you want to trash these MP3 files and replace them with AAC versions.

Well just put the original CD in your drive, make sure the songs you want are checked and then click Import. A dialog box comes up stating "One or more of the songs you have selected have already been imported. Do you want to import them again?" You can pick "Yes," "Cancel," or "Replace Existing."

By choosing "Replace Exisiting," iTunes places the original MP3 file in your trash, imports the songs with the new AAC format, and associates all of your tagged information with the new files. This is very awesome. Makes it much easier to re-import all of your files to AAC. It even keeps the original "Date Added" tag. Apple thinks of everything.

Of course, ripping your uninfected mp3 files to AAC means you
lose not only quality, but your control over your own media. You
will now only be able to play these songs on the 3 macs
authorized. And forget about playing them on a non-mac, non-

I'd have to double check this, but I'm prety sure that it's been stated already that AAC files encoded by the user do not require authorization. Only those AAC files purchased via the iTunes Music Store require authorization.

As for non-ipod mp3 players and other platforms' (windows, etc.) software mp3 players: I'm sure that AAC will be picked up by other players, eventually. Sure, if you want to rip your music and make it available via file sharing, no one else can use it, until their platform supports it. So what? This was a hint about not losing your mp3 information should you chose to re-encode your songs with AAC, not about the merits of AAC versus MP3's.

"Note : AAC files encoded from a source other than the Music Store (such as an audio CD) function the same as an MP3 file encoded from the same source in that there is no authorization required. So AAC files you encode yourself in iTunes 4 can be burned more than 10 times per playlist and can be played on more than three computers"

He's not talking about turning MP3s into M4Ps. He's talking
about turing AIFFs (from the original CD) into M4As (which have
no playing restrictions, and are at least equal quality to MP3s at
the listed bit rates).

iTunes4 and re-ripping to AAC

I haven't been able to hear any difference (using headphones) between my
MP3s encoded at 192kbps and the reripped AAC versions at 128kbps -
extremely unlikely to hear any difference on my iPod in the car!

And, reripping each song saves me about 2MB per song ... on a 16GB library
(over 2700 songs), I'm hoping to save a few GBs. As Anon says, just whack
the CD in and it'll replace your existing MP3s with AACs. To keep track of
which albums I've done, I've been dragging in the cover art from (wonder if future iPod software will show the cover art ... ?)

All the songs available from the Apple Music Store appear to be
encoded at 128kbps. Since I'll be buying most of my music
from there from now on, I mught as well re-encode all me CD's
at the same bit-rate.

iTunes4 and re-ripping to AAC

This must only work if the album was originally ripped on the same machine (perhaps then only when the original prefs or xml file is present), as I just tested this and did not get the same results.

Most of my music is ripped from my main workstation, but is stored and played remotely on my server. Neither placing the original CD in my workstation or directly in my server netted these would-be nifty results.

Perhaps it has something to do with where and how and if you use CDDB?

I think I'll try ripping in a new CD once as MP3, and then as AAC, both on the master server, and see what happens. I'd sure like to figure out a way to make this work; 10GBs of CD-ripped MP3s will be tedious enough to replace as it is, without also resetting genres, sub-genres, comments, playlist inclusions, et al.

This will work FOR ANY mp3s you may have on your computer. Just make sure the 'Track Name' and 'Album Name' are the same for the inserted CD as in the Library (i'm not sure if track lengths need to match). An excellent time-saver.
