I seriously doubt there is any software that will fix distorted recordings like that.(don't shoot me if there is) Only thing I know of is click and pop removers.

Anyway, what I suggest you to try is getting an editing program in which you can easily redraw the waveform. I know this might sound weird, but it can work. I once used the drawing tool in pro-tools to restore a distorted kickdrum in an 8 minute song. Fun fun fun!! lol Took me a long time, but it did the trick.
