For this short excerpt I began with a half-second clip of an old Microsoft mouse click, paired together as sixteenth notes. I laid this over both a distorted and reverberated low machine hum from outside of CFA, and the ticking of a stove igniter. In order to really fill the distortion of the low machine hum, I added some wind noise to add stress to the environment. To add ambience after the build, I used an excerpt from a Bach piano concerto, reversed it, expanded it slightly, and added reverb!
