Although many free jukeboxes duplicate the same functionality, this audio-conversion and CD-ripping utility earns points for its speed and ease of use. Convert MP3 can transform audio files among the four most popular formats: WAV, MP3, OGG, and WMA. You can configure the bit rates of your new files, but the program's wording leads us to believe audio quality is approximate. We would prefer to have the option to set specific bit rates such as 128Kbps or 192Kbps. The CD ripper can retrieve track information from the Web and does its thing just fine. The application's logically arranged interface makes it easy to add files to the queue, and you can convert tracks via the Windows context menu. In our tests, Convert MP3 demonstrated speedy performance, although the demo won't let you transform more than five files at a time. This program seems best suited to less experienced users who don't consider themselves audiophiles.
