Interesting concept for a wallpaper, I really like the gradient in the waveform that transitions from cool colors to warm colors as the amplitude increases from left to right. The only thing I would suggest is maybe adding some noise or subtle graininess to the dark gray areas to hide the banding formed by the light to dark gradient. Very nice wallpaper though.
Thank you for the tip! I will try it out and experiment with the grain & noise a bit; it might actually look good. I didn't even think of that when I did this one. & Thanks, I do appreciate it.
