Sound Drawing

When looked at the sound waves in the software, normally for the recorded sound, they have different wave patterns for left and right channel. So, what will happen when they are exactly the same or perfectly symmetry?
It's hard to tell if the sound wave pattern are symmetry with just listen to the sound. I copied and pasted the left channel to the right channel, then flipped the sound. When the wave patterns are symmetry, but the sound from left and right channels are different. There is difference between what we see and what we hear. For vision, symmetry is one of the principles for aesthetic. However, when it applied to the wave pattern, it may work differently.

Un-symmetry was also tried. When the right channel was the same as left one but only reversed, it was not nice visually, but sounded very interesting. It sounds like the wave travels from the left ear to right ear. 

That were two experiments to play with the sound with only vision, the result could be surprisingly interesting. This concept could be applied to the other sound in the further editing.
