How to convert AAC to MP3

Even if you don't own an iPod, it can be easy to get sucked into the AAC trap. It's the default format used by the popular iTunes Software to rip CDs, and the program will prompt you to convert WMAs to AACs upon initial use if you have the Windows format living in your music folder. That's not to say AAC--or WMA, for that matter--is a bad format to use; in fact, some users prefer it to MP3. Plus, more and more portable devices are adding AAC support. However, MP3 is still the most widely supported file type (they ain't called "MP3 players" for nothing).

If you have a library full of AACs and want to convert them to MP3s, you've come to the right place. I've put together not one, but two step-by-step tutorials to help you through the process. The first method is entirely free, and it's a good choice if you are on a tight budget, or if you only have a handful of files to convert. The downside is that the software used does not preserve all of the metadata of the file, so you will have to input ID3 tag info by hand at the end of the process. The second method utilizes a software that requires a license fee (after a 30-day trial period), but it fills in all the ID3 tag info automatically.

Note: either tutorial can also be used for converting among the various formats the programs support. For example, you can convert WMA to MP3, FLAC to AAC, or OGG to WMA.

Some files are locked by iTunes and it will not allow conversion (using iTunes).

As the other guy mentioned, iTunes does it in both OS's.

Just make sure, that in the preferences, you've got the option to rip cd's to mp3, not aac.

Then order your library by Media Type, selct all the non-mp3 files, right click, CONVERT to mp3.

Then delete aac file.

As simple as pie.

I've been wanting to convert my AAC files ever since I purchased my non-iPod a few months ago, but burning to CD-Rs was taking forever.

What a great post - thanks!

Wow. what a terrible, terrible article. Suggesting to anyone to use a conversion tool that doesn't maintain id3 information is a joke. Demand better! Those are some really ugly applications you suggested. Does CNET get a share of the sales or something?

So simple in iTunes. Set your importer to be mp3. Then select all your songs and choose "Create mp3 version" from the "Advanced" menu

Thats it! All the songs will be converted, all id3 info preserved. It doesn't get any easier or cheaper than that.

Major, MAJOR problem with your solution....This article was written specifically for those who have purchased songs from iTunes, which are protected, and iTunes does not allow you to convert AAC/M4P via this method.

What about quality loss in coversion to .mp3? Does iTunes lose less quality in converting than other software? It's almost not worth converting if the quality loss is there.

It works perfect in Itunes If anything all my songs sounded better in mp3 format when converted. I just converted my 11000 song AAC format library to mp3 using Itunes it took about 5 mins per album and was completely painless. And for the other people that said they can't convert songs its probably locked from itunes which why I only purchase drm free music from them.
by ecolinv November 14, 2008 1:35 PM PST
glade - If they sound even better then I guess there must not be much loss of quality, even though I've always heard going lossless to lossless is a signifigant drop in quality. Going from .wma to .mp3 was my main concern and I did notice some loss when I did that with iTunes a few months back. Thanks for your earlier reply.

Is there a down side to just using iTunes. Like everyone has said, iTunes does this for free. I've done it. And for protected music, I've burned the album to a disk, then re-imported the music off of the burned disc. Obviously this could be a pain if you have a lot of protected music but free minus the cost of the discs.

One name to remember...MediaMonkey.

Doesn't do a thing with your .m4p files, but for all the rest of your .m4a AAC files...works like a charm converting them to almost any other device-friendly format you can think of. Even does a pretty good job managing all that media on most MP3 players, too...including iPods.

I'm at a complete loss as to why anyone would convert from AAC to MP3 *on purpose*. Music you rip from your own CDs with AAC will not have DRM. AAC gets you higher quality at the same bitrate, or the same quality at a lower bitrate. I was very stoked when AAC became the default codec in iTunes - why would anyone want lower quality at higher bitrates when they have a choice, and there's no downside to using AAC. Makes no sense to me at all.

What's the point?

If you can't convert protected songs than what is the point of downloading this?

The big question here is "Why?" What has possessed you to write this article? I can't answer this because I don't know Jasmine France's motivations, but it's safe to say that thee is no benefit to converting your files to MP3's is a serious step backwards unless you're interested in posting your music on a peer to peer or bit torent site. I say just leave them well enough alone.

It was based on a reader question related to buying a non-iPod MP3 player but having a library full of AACs. I recommended some non-iPod devices that support AACs as a first choice; a tutorial in conversion as a second choice.

Well here's one (applies to me). My iTunes music library is in AAC. I have just acquired a new PDA and would like to listen to some of my music on it. It only plays MP3.

@Tumbleweed - Not to put too fine a point on it, but you should have thought of that before you bought your PDA. Having to degrade your entire music collection forever just to be compatible with a PDA seems like way too high a price to pay. How long will you have that feature-dumb PDA? A year or two? But now you're stuck with a degraded music collection for the rest of your life. I don't get it.

Hey, some of you need a chill pill. Just because you can't see a reason to do this, doesn't mean that others don't have a damn good reason to do it. First of all, MP3 is NOT of inferior quality to AAC. Just the opposite. Don't try starting a war over it, just accept that as my own opinion. Second of all, AAC puts your own content in the Apple jail. Why in the world anyone would accept such an outcome is way beyond sanity. AAC cannot play in the majority of MP3 players, so there is every good reason to break your content out of jail, and put it into the free (as in freedom) format. I don't want any of my content into any kind of jail, so I don't buy itunes music. I personally think that people who spend 10,000 dollars to fill their Ipod, and get content that is stuck in Apples jail, are nuts. I think that people who spend 10,000 dollars on content, should get MP3 content, as I have. I personally think that DRM stinks to high heaven, and we should all refuse to have anything to do with it. That way it will die and go away. What DRM does is it puts someone else in charge of your content. Let us all remove the DRM and then our computers can do their job. For example, I can put MP3's on my home server, and serve it to myself around the world, or just to my own network. There is no way Apple is going to let you have that kind of freedom. They will let you have 5 of this or 3 of that, IF you have the passwords and permissions just right, and IF you allow them to put a bunch of crappy restrictive software on YOUR computer. That is assuming that they will allow you to run THEIR software, and if and only if THEIR software isn't broken.

I have a sore spot for DRM, as I recorded a bunch of Movies with Windows Media Center, and stored them on a USB connected hard drive. I thought I could carry this drive around, or even just reformat my computer from time to time. But lo and behold, the movies are crapped up with DRM. These are movies that came in to my house over clear unincrypted channels. There is no legal way, or easy way, to remove the DRM. The movies are a complete loss, because I lost my main hard disk and needed to reformat. So the DRM data is corrupt. There is no way to access these movies now, even though they sit happily on my external and undamaged hard drive. I am really unhappy after spending thousands on a Windows Media Center PC and associated hardware. How much gall did it take to DRM the movies that are on unencrypted channels on my TV? What the hell? I could have put a tape in the VCR and it would be easier. This was Microsoft kowtowing to Hollywood, and creates an untenable situation whereby the actual things that the computer is best at, that is serving over networks, are completely blocked. Oh, and by the way, Microsoft will allow you to play the movies over a network, but you have to buy more hardware and software from Microsoft to do it, and there is absolutely no chance at a backup, because the backup cannot play through the DRM block. Oh, and I didn't mention the fact that Microsoft's DRM system is known to periodically break down, causing irretrievable loss of content, as what happened to me.

Don't tell me that cannot happen to Apple, especially after their battery debacle. Which was, if you don't remember, "so you need a new battery?, just buy a new Ipod". The EU has presently made that particular type of racketeering illegal.

John.

is incredible - that try to get money from the customer at this time, when is completely FREE and anybody can do it by itself.

Just Open I-Tunes, Select the songs in Format AAC, burn the song in the CD as AUDIO CD WITH Max. 360 Kbps to keep High Quality of song, and then bring it back to I-Tunes as MP3 with high Quality as 360 Kbps.

That way will have the new files as MP3 with HIGH quality and with the correct format to play at any device.

So, don't bother to subscribe to any membership, everything that is Only is FREE

Didn't work for me. Apparently all of my songs in iTunes are protected.

Great article. I want to move my iTunes library, including songs I bought on iTunes, to my new phone that only plays MP3.

One problem - when I download the Easy CD-DA Extractor software you recommended, my anti-virus software says the file has a virus. I contacted the publisher and they claim it's a false positive from the anti-virus software. Before I load up the software, I want to be sure there's no virus. Any advise? Can anyone confirm that the file is safe to use?

Thanks
