While there are ways to reduce the static sound that results from a clipped waveform, there is no true way to recover the lost information. It's no different than an overexposed photograph: you can darken the while areas, but you will never recover the textural detail; the area can only become a gray mess.
Looking at the waveform, I am fairly disgusted. It reminds me of Californication. A frequency analysis reveals that all frequencies above 10kHz are nonexistent. (Of course, considering the sampling rate). I didn't check the RMS of the file; I assume it must be very high. Tsk tsk! There's not much that can be done here besides basic clip restoration. music_bar_ku04.flac Jam it back in, in the dark.

You can't truly create information that was never there in the first place. This is especially true for complex sounds such as transients and instrument overtones. In this file, the upper frequencies simply do not exist. What would you generate them from? (I'm actually curious here.)
Any way, I don't think the file needs any more filters applied to it than already have been. It's had enough, I think. Most amazing jew boots |

But what I'm wondering is, how does this software work? How does it "know" what kind of information to add in? For example, let's say we have a 22050Hz waveform audio file of a violin playing. At this sampling rate, frequencies above 11025Hz cannot be reproduced because the sampling frequency was lower than the frequency of the sounds in question. The timbre of a violin is very complex, especially in the upper treble frequencies. Would this software be able to determine the nature of the sound in question and add in the proper harmonic content? How does it determine this? What is it working from? Wouldn't any high frequencies generated by this program only be extrapolations based on the available data?
I'm not trying to be argumentative here, really. I guess I'm just a skeptic at heart. I have no reason to believe that you're lying, but I just can't see how such a program would (or could) produce realistic results. This thing is sticky, and I don't like it. I don't appreciate it.
