Over the past month I have made it my goal to stop using the proprietary MP3 format for audio in favor of the free, open standard Ogg Vorbis format. The primary reasons for doing this is 1) Modern Linux distributions do not ship with mp3 support built in (due to licensing constraints) and 2) My Sanza Fuze supports ogg format. Add these two elements the fact that ripping a CD into ogg format is far faster than ripping it into mp3 format, and you can see why I would choose to migrate to ogg.
Now the problem lies in the fact that I have a fairly large collection of music files that are all in mp3 format. Having to convert 5,000+ files, one by one, via command line would cause even me to pull out my hair. So I decided it was time to search for a tool that would handle the conversion for me...
