http://www.go2linux.org – I have been buying some music on itunes, it comes in AAC (.m4a) format, which is great to use in itunes (I have it on a Windows 7 running over VirtualBox), or to use it in my iPod Touch or iPod shuffle, but if I want to use it in my cell phone (an old one which does not support AAC format) I have to convert it to mp3, I have to also convert it if I plan to use mpg123 which I use a lot. Well lets go to learn how to convert from AAC to MP3 <!--break--> I will use Arch Linux for this, but you can use any distros, just be sure to install faad and lame. On an Arch Linux box run: sudo pacman -Sy faad2 lame Once installed, run this commands to start converting. faad file.m4a This will convert it to wav, and then run: lame file.wav file.mp3 That is it, you now have an mp3 version of your original aac file. You may want to make this automatic, for that you can use a small script, this is just an example, you can create a better and more elaborated one. #!/bin/bash SAVEIFS=$IFS IFS=$(echo -en "\n\b") for f in * do echo "$f" done IFS=$SAVEIFS If you have any suggestions to improve this, use the comments please.
