This audio converter’s extremely narrow focus prevents it from trumping more-powerful competitors. WaveNet mp3 simply compresses WAV files into the MP3 format. We really wish the program also supported other popular audio codecs, such as WMA and OGG. The nonresizable interface lacks polish but at least is easy to use. To convert tracks in single or batch mode, you simply locate the files on your PC and press a button. You can add information for artist, title, album, and genre, as well as specify bit rate, frequency, and audio quality. However, you won’t find any advanced features such as support for the VBR compression scheme or the ability to normalize tracks in batch mode. Happily, WaveNet mp3 has a saving grace: It’s completely free and doesn’t place any restrictions on usage. Folks seeking advanced features or support for multiple codecs should look elsewhere, but those in need of a simple, free MP3 encoder will find this program does the job.
