[xfce] good replaygain software?

http://ubuntuforums.org – I guess the title explains it. I tried soundKonverter (Qt app) but it doesn't seem to work very well. And, being a dolphin user, I figure I have a fair amount of KDE dependencies installed. And xfce has that handy kde and gnome services setting in startup. Not particularly interested in scripts. That shouldn't be necessary in 2013.I'd rather try running foobar under wine or virtualbox. It'd have to work with flac/aac/alac/maybe ape as well as mp3. Thanks in advance. (Hardware)
