 Graphic WAV Level OCX

I didn't see any existing control to perform this kind of function yet,
even on winamp or other players, they perform this function themselves. But
actually it is not very difficult, the only thing you need to do is to get
the wave information from the sound file and perform a Discrete Cosine
Transformation. After that, the data is what you want to show, you can find
the arithmetic of DCT anywhere on Internet.
