Christopher Montgomery of Xiph.org fame has an excellent de-clipping (among other things) app called postfish (http://www.hydrogenaudio.org/forums/lofiversion/index.php/t22051.html). Are you familiar with it? Any chance of incorporating his de-clipping code in Rezound?
+1 it would be great to improve the "menu -> Remaster -> Unclip" feature.
