What this shows: how tall each part of the wave is = how loud that range of sound (bass on the left, highs on the right) is right now, compared with the loudest part (it auto-scales so any song fills the view). The white VOCALS zone is where voices live. If the bass side stands taller than it, the bass is covering the vocals. Keep peaks under the red dashed line.
