iTunes is much more than a digital music jukebox. It's capable of handling many different tasks involving digital media. Some of iTunes' most popular features include buying music and vidoes online, burning CDs, and syncing files with your iPod or iPhone.

But one of the lesser known functions hidden within iTunes is the ability to convert audio files.

Requirements:

• iTunes (http://itunes.com; free download)
• At least one song in your iTunes library that you want to convert to a different format.

Why would you need to convert an audio file? Converting audio file types can be useful in many different situations. Here are a few examples:

• You have an AAC file in iTunes that's not compatible with your Zune that can play MP3 and not AAC files.
• A WAV file needs to be emailed to a client for approval but it's too big. You need to convert the file to an AAC so it's small enough to easily send via email.
• You are making a music video and want to use a song you got online as the soundtrack. However, the editing program won't import the song because it doesn't support MP3 or AAC.
• You need to remove the DRM (Digital Rights Management) from an AAC song you purchased from the iTunes Store (see step #7).
  

Many programs that convert audio files into different formats are pretty complicated and usually cost money. But not iTunes. iTunes is simple, fast and best of all... free.

How to Convert Files to Other Formats Within iTunes

1. Launch iTunes. It should be listed under your START menu (PC) on in your Applications folder (Mac).
   
   
2. Open the preferences window (iTunes > Preferences) and navigate to the Importing options screen. Depending on what version of iTunes you are using, the Importing options may be in a different place. Older versions of iTunes have a separate orange Importing icon [click to see screen shot] in the preferences window. Current versions of iTunes have the Importing options hidden as a nested tab in the Advanced section like in the image below.
   
   
   
   
   
3. What format would you like to convert your audio files to? iTunes is capable of converting to/from several formats including: AAC, AIFF, Apple Lossless, MP3 and WAV.
   
   For example, select MP3 if your friend wants one of your AAC songs converted to an MP3 file so they can listen to it on their non-iPod/iPhone music player. iTunes also allows you to dictate a bitrate quality for the song(s) that you want to convert. 128 kbps is the default setting and should be a high enough quality for the average person. Select a higher bitrate if you desire.
   
   
   
4. Close the preferences window and find the song(s) that you would like to convert in your iTunes library. You can hold down the Shift or Apple (Alt on Windows) key and select multiple songs at the same time if needed.
   
   
   
5. Select "Convert Selection to..." from the Advanced menu or right-click on one of the selected songs to bring up a contextual menu.
   
   
   
   
   
   
   
6. Once the conversion process begins you will see an orange spinning ball in the iTunes Source window. You can click on this icon to see the progress of the conversion process.
   
   The time it takes to convert the song(s) will vary depending on the number of songs, the type of conversion, and the speed of your computer. You may want to quit other applications if you are in a hurry and need to speed up the conversion process. When iTunes is done converting the songs you will hear a chime. This is the same chime sound that iTunes plays when it has finished burning a CD.
   
   
   
7. If one of the songs you are trying to convert was purchased from the iTunes Store and isn't in iTunes Plus format, then you will get an error message saying that protected files cannot be converted to other formats. The best way around this limitation is to burn the protected song(s) to an Audio CD (not a Data CD-ROM!!!) and reimport them back into iTunes.
   
   
   
   There are several "underground" applications, like Hymn, that will remove the DRM protection from a song purchased from the iTunes Store. However, Apple is constantly looking for ways to disable songs that have had the DRM tampered with. Don't waste your time. Just burn an Audio CD and reimport the songs back into iTunes.
   
   
   
8. Once your song(s) have finished being reimported/converted, search your iTunes library for the files. You should find 2 versions of each song you converted. One is the original file, the other is the converted version. If you only want the newly converted version of the song, then delete the old one. One easy way to tell the 2 songs apart is to view your iTunes Library by Date Modified. The newer song is the one you just converted.
   
   In the image below, I have 2 versions of the song called "BPD (Album Leaf Remix). When viewing my iTunes Library by date modified, I can easily see which file was most recently created.

Hi, I just downloaded a song from the iTunes music store. It works great and is on my iPod. My brother just bought an iRiver brand mp3 player, but since the song is in protected AAC format, it cannot go onto his player because it to AAC. Is there a way to screw the copyright laws and change it to mp3, wav, or wma format? ~ CTASH1212

when I try to drag Mp3 files from my Itunes Library into my Ipod an error appears that says: "Some of the songs in the Itunes music library, including the song "(song name)", were not copied to the Ipod "(My name)'s Ipod" because they cannot be played on this Ipod" I've searched your site and many others and can't figure out the problem. I have a 40GB Ipod, I use Windows XP, I tried converting the ID tags but that didn't do it. Please help me, I'm desperate. ~ dmetter
