Jaksta Music Converter is a commercial audio converter. It can be used to convert most audio files into the most popular audio formats. There is an option that lets you convert files so that you can play them on iTunes, which optimizes the conversion for iTunes and all the devices that sync through it, such as the iPhone, iPod Touch, AppleTV, iPad, and all the other iPods.
Graphically, this converter looks nothing like all the other audio converters I have tried. The graphical user interface is very clean-looking and the colors used make it easy to focus on what is important. You will notice a big space where you can drop files to add them to the conversion queue. At the bottom of the screen, there is a toolbar with all the available output formats. You simply click on the format that you want to convert files into. Unfortunately, there aren't any conversion options that you can change other than the format that you want to use.
In my testing, I was able to convert MP3 files into AAC for iTunes. The process was really quick and smooth. But the trial version of Jaksta Music Converter will only let you convert half of your files.
