Why is my waveform uneven?
In combining different frequency signals with differing phase relationships, the result is often a distinctly asymmetrical waveform, and that waveform asymmetry often changes and evolves over time, too. That's just what happens when complex related signals are superimposed.
Why are audio waveform not symmetrical?
High-pass filters, and aggressive low-end processing are common causes of asymmetric waveforms. Adding gain to asymmetric waveforms will further intensify the disproportionate placement of energy.
Are waves always symmetrical?
They are roughly centered around the central axis, but there is no need for them to be perfectly symmetrical. In fact, it's almost impossible to see a perfectly symmetrical waveform. There are a couple factors that contribute to this.
