View Full Version : AAC 128 is great so far-My story from a Mac User

I have to say that I almost went insane encoding my library to AAC. I was sckeptical as were others but I wanted to see how it would sound. So I did a few albums first, than I was hooked! It was only 1 week ago that I undertook this task and I can now say that I am so far verry happy with the results!!

: )

Much of my music was encoded as AAC directly from CD's but I also had many downloaded MP3's. (1000 + MP3 Tracks)

I will end the debate now. Music encoded as an AAC file directly from an Audio Cd sounds better than the AAC's encoded from MP3's or better than Mp3's encoded directly from Audio CD's even at 160 or 190 Bitrate. Duh
If you have got your MP3's encoded at 160 or 190 Bitrate and you convert them to AAC as far as I can tell, you should notice no degradation in the sound. At least I haven't! If your MP3's are lower in bitrate then they are obviously not going to be as good as the standard 128 AAC, but they as well should not be degraded in sound. You will just end up with an AAC file, at lets say 64 bitrate, etc.

Either way, if your a MAC user and you use an iPod, I would reccommend encoding as AAC. As some others have said you get more tracks for the room. I got 1250 songs encoded as AAC to fit onto my girlfriend's 5 gb iPod. Yes that's right! I've got more than the predicted 2000 on my own 10 Gb and i"m loving it.

But even moee importantly, and not mentioned as much is the better quality audio. (Mpeg 4) In my opinion AAC just sounds better. Period. So not only is it a smaller file size but it is a better sounds, especially on tracks encoded directly from an Audio CD.

It took me 4 1/2 days straight to do my library.

But i'm not stupid either. I have kept ALL of my MP3's (in case I decide at some point to switch back) and I would reccommend that to anyone who has the room on a back up hard drive.

Oh yeah and then there's finding all of the cover art! I reccommend using Amazon for this. If you don't care about being this anal retentive than I completely understand but I have been able to get almost all the art work for my 2000 plus song library!

That, I'm still working on!

Other users have noted these issues, my opinions on them:

*Static in songs: I haven't noticed at all.

*AAC +: Wouldn't wait around. AAC is good enough and with AAC + you will almost definitiely have a larger file size, defeating the purpose of encoding at all.

*Encoding MP3's in iTunes: I used iTunes for everything. Wouldn't waste your time looking for other software until rivaling software exists.

*160 kb AAC?? What? Why would you waste your time encoding MP3's or Audio CD's to 160 KB AAC??? Larger file size, quality is almost the same! Generally 500-750Kb per file more for a 160 versus as 128. That's a lot when you multiply it by 2000 or 10,000, (at least this is what I have found in my tests)

I hope this info helps those who are thinking of diving into AAC. I surely like it!

all the space you saved by switching from MP3 to AAC, you lost by adding cover art!

the cover art is part of the tag, adding size to the file.

Yeah, that's what I thought but it hasn't. iTunes is keeping all my artwork in a seperate folder. I noted the size of each track before and after the addition of art. It didn't change. I even opened the songs on a differen't mac and they were the same as before the addtion of art. Tags are not getting bigger.

I can't explain it!

Also, generally your opinion is a little off because the general size of a downloaded artwork is 10-15 k MAX. This was a limit I gave myslef. I am a designer so I am always aware of file sizes. So an mp3 at 5.5 mb recoded as AAC is 4 mb. Even if the artwprk increased the size, it would be 15 k to tha 4mb which IS NOT the same as what it would have been as an MP3

I guess if your adding 1 and 2 mb artowrk that your theory might be right but for me I have only added maybe 500K total of artwork to my library which is nothing!

But thanks for the heads up, other users might not already be aware of this...

As I deleted the artwork from my stores files, the size of my library went down bit by bit... that's where I base my info. For example if an album was 75.4MB with artwork, after I deleted it was something like 74.9 I'm making these numbers up, because I didn't write any of them down, but the size DID change when artwork was removed.

Actually, the guy who partially created the whole aac codec thingymabob says that the eminently available aac+ will actually have cd quality at 64kbps. Im waiting before re-encoding my whole mp3library :D

Ben,

Don't waste your time looking up album covers manually on Amazon. Try Clutter:

http://www.sprote.com/clutter/

Clutter has an option under the File menu to Copy Cover to iTunes. Dropping cover art on your desktop like virtual CD cases using Clutter is cool too!

I was looking for something like that but couldn't find anything...Thanks a lot

I thought something existed that would do this but I wasn't sure if it had been written yet. It seems there are not many who know about it...You should post a general...this would help people, I'm sure of it!
: )

I have started using Clutter and Synergy (still trying to decide which one to keep) which both automatically search and download album covers, so I'm now removing the artwork that I manually added in when itunes 4 first came out. I'm regaining between 500k-5mb(!) per album (depending on the size of the image and number of tracks). As long as your mp3s are tagged properly the 2 apps mentioned have no prob finding the correct art (as long as amazon has it).

I can confirm that removing artwork from tracks does free up disk space, contrary to early reports (in the old forum) that the file size remains the same, unless they have changed/fixed something in itunes 4.01.
