Is it worth converting all mp3s to AAC?
Just wondering if it was worth converting my MP3 files that are all 192 to aac files to get more storage space?
Thanks

Some say no, but I did. I haven't had a chance to put them on my ipod yet, but I will after work. I tried a few and they sounded fine to my ears, if they don't to anyone else, I don't care, it's my ipod.
# 2 Re: Is it worth converting all mp3s to AAC?
for a test i converted on of my albums from mp3 to aac and when i played it on my ipod, everything sounded fine. with a lil ole 10 gig ipod, space counts and i was running out of room. now granted, an audiophile with a high end system or high end set of phones my notice a difference, there is no difference in my $20 headphones or my 10 year old explorer with the factory stereo!

You are just plain wrong in the head if you convert from MP3 to AAC, nothing more.
You will lose quality. It will sound worse. It will NOT take up less space (if your converting to the same bitrate).
Sure you may say, "it sounds fine to my ears", but thats a biased viewpoint, you already know that it will sound fine before you even hear it, hence the statement.

Don't worry about other people' opinions. Just try it for your-self and find out. All that matters is if it sounds good to you or not. I converted all my mp3s greater than 128 kb/s to AAC on my ipod, and I did not hear any difference.
Conoverting from 192 kb/s mp3 to 128 kb/s AAC will make the file smaller.

Yeah, but you'll lose sound quality. Wheres the advantage in that, the iPod has a lot of space?

# 6 Re: Is it worth converting all mp3s to AAC?
If you convert directly from MP3 to AAC, yes there will be a quality loss (though not noticeable, IMO). It's like making a copy of a copy of a copy. You copy it enough times, the file degrades. However, if you re-rip your CDs directly to AAC, you will not notice any difference as you are encoding from the original source.
Also, Adam is right that you won't free up any space if you rip at the same bit rate. I originaly had my CD collection in as 160 MP3s. I re-riped them as 128 AAC and was able to gain 10 MB of space per album. With an extensive music collection, and an old 10GB iPod that savings was significant (I now own a 30GB iPod, so space is less of an issue for me).
Since you currently are at 192, switching to 128 AAC will definitely free up space for you. If space is important, then switching may be right for you. Otherwise it comes down to personal preference and if you want to invest the time in re-riping your collections.
You may also want to check some of the other threads on her for the AAC v MP3 debate to get an idea of some of the other opinions about the formats.
Good luck.

I swear I am going to post a huge thread about AAC vs. MP3 when I get some new speakers, and get the ##### stickied!
There is so little knowledge about it, people just beleive what they hear from Apple about it being better quality and smaller.

# 8 Re: Is it worth converting all mp3s to AAC?
I converted the latest Dave Matthews CD, Some Devil, to AAC (actually re-ripped it) and noticed a significant improvement in lower-mids and bass frequencies in both my headphones and through my home system. I actually noticed Sub response as opposed to nothing with MP3 format with a 160 bitrate. To each his own, but I'm starting to be a believer.
Particularly notice a difference in live recordings

# 9 Re: Is it worth converting all mp3s to AAC?
No, I'm not against ripping to AAC, thats fine, go for your life.
I'm against people who convert directly from MP3, and then swear black and blue that they will get better quality in a smaller file.

# 10 Re: Is it worth converting all mp3s to AAC?
Exactly!
So many people don't realise this.

Nobody in this thread said that converting from MP3 to AAC will give them better sound quality.
What people are saying is that if you have your MP3 files encoded at >160 kb/s and you are running out of space, encoding the files from MP3 to 128 kb/s AAC WILL save space and for many people the difference in sound quality is not noticeable or neglible.

# 12 Re: Is it worth converting all mp3s to AAC?
yeah, i am not saying i did it and expected quality to get better or even stay the same. I assumed there would be a slight drop in the quality. i didn't do all of them, just a few to try it out. Again, with cheap headphones, and a cheap car stereo, I don't THINK the difference is that noticable.

# 13 Re: Is it worth converting all mp3s to AAC?
I had 2700 mp3's that were ripped at 160. At that setting I had approximately 3.1 gb free. When I converted them to 128 aac I now have 6.8 gb free. To me they sound just as good or better as when they were at 160. I gladly accept the loss of sound quality, to me it has not been noticeable.
# 14 Re: Is it worth converting all mp3s to AAC?
I have changed my entire MP3 to AAC and saved like 1GB of space and really haven?t notice a drastic change on the sound quality, its the same to me !

# 15 Re: Is it worth converting all mp3s to AAC?
Just for the heck of it, I did a size test of AAC/MP4 vs MP3
All 150 or so CD's are ripped with EAC and compressed with Monkey's Audio at the "Extra High" profile. This is my archive collection and they're also tagged appropriately.
I used the diskwriter output in Foobar 2000 to convert the 1965 files to both .mp3 and .mp4.
.mp3 was done with Lame 3.90.3 and using "--alt-preset standard" as the command line option.
.mp4 was done with Nero's AAC component and using the "Extreme" profile.
Statistics
APE: 55,118,689,624
MP3: 12,783,519,517
MP4: 12,733,927,092
I haven't done any ABX'ing to see what the quality differences are, but most people on Hydrogen Audio say that the "Transparent" profile in MP4 is just that and "Extreme" is one step higher on the quality ladder.

What do the numbers mean? Size?

First I backed up all my mp3's, and then let itunes do the convert, and i gained about 2GB of space on my ipod(which was nice to have), and i noticed the quality of the AAC file sounded better to my ear{Many would argue, some would dissagree}.
What i would do{if you haven't already} is ripp one cd listen to it and compare the file size, & sound quality to your mp3.
Note: i converted most of my mp3's from 128kbps-320kbps mp3 to 128kbps AAC.

You can't gain quality from nothing. Its like getting more water when your pour water into an empty glass.

I find myself reluctantly agreeing with Adam on this one,
ALTHOUGH
I did a few test's myself and I found that when I ripped from 192mp3 to 128aac the bass and treble were slightly exagerated on the aac version and to some people this might sound like they are getting higher quality, of course the same effect can be achieved if you use the equaliser with the original mp3. I also noted that the loss in sound quality was absoloutely minimal and my ears didn't notice it, in fact the increases in bass and treble made the music sound richer in a way.

# 20 Re: Is it worth converting all mp3s to AAC?
Sounds like this one could use a *sticky* maybe or someone (like Adam maybe) could start a real thread about AAC vs MP3 issues.
But so far it makes sense, too bad the majority of people are still (and probably always will be) stuck in the mindset of "Oh... so this 128 Kbps rate will allow me to put even more music on this tiny little thing? Cool... that works for me."
Tony Robbins (yes, that one) has a philosophy that states everything we do in our lives is done for one of two reasons: we either do something to avoid pain, or we do something to gain pleasure. Note that these are mutually exclusive things. In other words, you can do something to avoid pain and you're not doing it just because you don't want pleasure. It breaks down to this: People will do more to avoid pain (they'll encode at a lower bitrate sacrificing quality because they don't want to run out of space) than they will to gain pleasure (higher bitrates and better quality music).
It's a nutty idea but when you think about it Tony is just making sense. It's not magic, ya know...

Oh trust me, I will. I just can't know, I'm in the middle of the most important exams of my life. Later in the year when I get the iPod and a high end speaker combo, I will educate people.

Well hell man, I'll get started on an AAC vs MP3 FAQ for this place and if we butt heads enough we can put together a nice piece of work. I'll put together a draft of info that might become a *sticky* and make us BILLIONS!!!!
