Speaking of file type conversion, my daughter recently upgraded to a Nintendo DSi from her old DS that died. The DSi will let you load and play music, but only supports AAC format. Since my entire library is either mp3 or flac, my obvious next question is:

Can someone recommend a free converter to go from MP3 or FLAC to AAC?

My plan is to make a small duplicate sub-library (i.e. keep the original MP3's and flac's) of just my daughter's music for the DSi specifically.

Thanks!
