crt audioscope


CRT Audioscope is a project that explores the technical aspects of the crt screen. For this installation two crt screens are rewired to accept audio stead of video. A small interface using potmeters, Arduino and Processing was created to generate a stereo audio signal. The left and right audio signals are, respectively, wired to the horizontal and vertical deflection coils of the crt, which makes for interesting lissajou figures to appear. By turning the knobs the user can explore the relation between audio and video.
