AudioConverter Studio 6.0
AudioConverter Studio is an Audio Converter and a CD-Ripper combined into one easy-to-use utility 
It does CD to MP3 or WMA conversion on the fly, rips CD tracks to WAV files and does WMA to MP3, MP3 to WMA, FLAC to MP3, MPC to MP3, OGG to MP3 and WAV to MP3 conversion. Plus, it comes with CDDB support, so you don't have to enter MP3 tag data manually and the program preserves id3 tags when converting a higher quality file to the lower quality.
