From Mp3 Converter:
Super MP3 Converter converts audio files among MP3, WAV, WMA (Windows Media Audio), OGG, VQF, and AC3 (VOB) formats. Its user-friendly interface supports both drag-and-drop and shell operations of Windows Explorer. Most work can be done automatically with a few mouse clicks. You can convert many files in batches regardless of their source and target formats. Super MP3 Converter also supports playback of all audio files with its built-in player as well as audio-volume normalization, and encodes with Windows Media Audio 9 (WMA). Version 4.2.11 may include unspecified updates, enhancements, or bug fixes.
