AnalogWhole (Freeware / Windows) is a free Windows application that allows you to consolidate all your music into iTunes as MP3 files. Any music that is playable in Windows Media Player can be re-recorded as an MP3 file. Just tell AnalogWhole where your music library is, and it will automatically re-record the files as an MP3 file. In addition, it will add the converted song to iTunes for you.

With AnalogWhole you can convert all those WMA or WAV files you have that won't play on your iPod into MP3 files that will/

The way AnalogWhole works is pretty straightforward. Almost all PC soundcards have the ability to simualtaneously play music out one channel while recording music on another channel. The standard Windows audio mixer component allows the output channel to be routed back into the soundcard input channel. AnalogWhole uses the COM interface to Windows Media Player to play the music file and while it is playing, it records it and encodes it as an MP3 file. All tagging info (i.e. artist, song title, album et cetera) is transferred to the MP3 file as well.

Disadvantages:

• Unlike AnalogWhole many other DRM removal software tools like TuneBite and SoundTaxi support high-speed recording so they can record much faster than in real time.
• AnalogWhole is a lossy DRM removal software.

Download AnalogWhole. It is absolutely free.
