Not a qt app but, I just installed it and was pleased with first use. Seems I had all dependencies but two already installed (no undesirables required, it seems) . So, build and install went quick. Program itself is small, loads quickly with a pleasing interface, and is easy to use. Took only 9 seconds to convert a 4:30 MP4 to MP3.
