I tried this on 10.2.3, but could not get it to to work. Dropping an AIFF onto the window, set to convert to WAV, did nothing -- the file never appeared anywhere. Some sort of status bar and/or program feedback is absolutely needed. Numerous other problems: the program has a plugin icon (big no-no), the interface is virtually unlabeled, the help is lackluster at best, grammar problems abound... The list goes on. I think we need a program that performs as this one promises to, so I'm not giving it 1 star. I await future releases.
