Chances are, if you've searched the web for a universal video converter for the Mac, you've come across VisualHub
(formerly iSquint). Now, the makers of VisualHub have brought the same conversion magic to audio with AudialHub version 1.0
AudialHub can easily convert audio files to most any format of your choosing, including AAC, MP3, WMA, AIFF, WAV, Apple Lossless, 3G (cell phones), Ogg Vorbis, FLAC, and Audio and MP3 CDs.
AudialHub brings the same simplicity-and optional advanced features-that VisualHub offers. If you want to use AudialHub for quick and dirty conversions, simply drop in some audio files, choose the output format, and hit start. That's it!
If you want more advanced conversion, you can look into the advanced settings, where you can set bitrate and channel, trim the audio file, add tags and comments, etc...
AudialHub also offers a Quick Preview capability, so you can instantly preview compression quality and trim settings before you convert. AudialHub also supports simultaneous conversions in separate queues, each with their own setting.
AudialHub is currently offered with a free trial
; after that, it'll cost you $18.81 (you get a $4 discount if you're a current owner of VisualHub). AudialHub requires Mac OS 10.4.11 or later.
