viewing waveforms

["Rich Peet" <>]

I lack some basic info.

What causes a sound as seen on a waveform to go more positive or more
negative than centerline?

Linked is example where both negative and positive sounds can be seen
and the background can be seen as not having any DC offset.

Is this a different type of sound wave than when things are seen centered?
