iFunia says AudioConverter is now available on the Mac App Store. It requires Mac OS X 10.5 or higher and costs US$9.99. A demo can be downloaded at the iFunia web site (http://www.ifunia.com).
iFunia AudioConverter is a tool for converting popular videos to common audio formats, including MP3, WAV, WMA, OGG, AAC, and others. The application also offers additional editing functions to join several music clips into a single one. Just set output settings for sample rate, channel, encoder and bit rate.
iFunia AudioConverter supports batch conversion, so users can process multi-conversion at the same time. These output audio formats can be supported by almost all the players like the iPod shuffle, iPod touch, iPod classic, iPod nano, Zune and more.
