Sound sponge mystery

A friend of mine recommended a Mac program called Sound Sponge for automatically marking and cleaning out clicks and other problems from recordings taken from vinyl records.. but the only program called Sound Sponge (or technically, Sponge, but it’s located at soundsponge.org) is a small tool for converting audio file formats and is not what I’m looking for. I think my friend mixed them up and I’ll ask him, but just in case he doesn’t remember, does anyone else know what he might have been thinking of?
