In the second soundtrack as the character walks past the holes in the ground, we hear static coming out of the ground. It is to represent the anger created when thinking about horrible news, and the electric is the danger created when you’re mad. The static comes from an old school hairdryer. The waveform is shown below.
Below we can see the audio chain in effects, cutting out the top end with an 8band EQ, adding some sound erosion at 2.5kHz and also some fully harmonic distortion.
