I'm no expert and have never successfully fixed a clipped recording. However I'm pretty sure that no software could fix this. It isn't clipped as shadow_7 pointed out. It doesn't go above 0 dB-it looks like it brickwalled and peaks around -3 dB. I think all the clipping repair tools rely on the wave form showing actual clipping (going over 0 dB.) And even in the best case scenario, it's pretty hard to figure out how to use them successfully.
