its basically Izotope's multiband compressor, automated.
I use Izotopes plugins for various post tasks, and they don't do a passable job when left on preset settings, auto settings or learn settings, they always need tweeking, and in most cases need setting up from scratch. i have yet to come across a single processor which can "automatically" fix sound problem without needing some tweeking by a person;
why anyone would put professionally mastered tracks through an automated multiband compressor...argh...
reading some reviews, it looks like its using a more complicated tool to basically "Normalize" a music collection...that function found in CD burning software that I'm pretty sure no producer ever uses...
