Specter is installed in the elevator at the Tang museum. The piece was commissioned for an ongoing show called<a href="http://tang.skidmore.edu/index.php/calendars/tag:36/year:all"> Elevator Music </a>. </p><p>Specter is a sound sensitive installation. Sounds generated in or near the elevator cause the orbs to glow at varying hue and intensity. This profoundly impacts how the viewer perceives and appreciates sound. It places a new value on the incidental ambient sounds of the elevator and building and inspires passengers to generate their own sounds. The passengers themselves become the sound piece.

  Each orb contains a microphone, 3 high power LEDs and analog/digital circuitry for analyzing and processing ambient noise. The frequency of the sound controls the color and the amplitude controls the brightness. </p><p>
