Though built from blunt tools, Switch is sonically and conceptually complex. The piece consists of only one signal (white noise coupled with a 660 Hz sign tone) which is switched back and forth from left to right at a decreasing rate as the piece progresses. Listeners report synæsthetic responses such as tingling and hypnogogic imagery, and even believe they are hearing a different pitch in each ear. Switch is a perfect demonstration of Kantian subjectivity; he said that the human can never truly experience the objective world because his or her perceptual system distorts it.
