Distortion on capture

Hi all, I captured a concert and i think the line in was set too high as i didnt have a problem with a previous capture, but with this capture of a concert ive got distortion, its mostly noticeable on the low bassy beat and the highs distort aswell. Its rather annoying after a while.

Is there any program (goldwave maybe?) where i can attempt to filter this out? If it can be done on goldwave how can i do it on it?

Thanks...
