The subjective dimensions of sound underpin Hecker’s investigations. His installations shift and vary depending on the listener, both in terms of each individual’s physical location and his or her personal biases and points of reference. Hecker takes as a starting point the fact that listening is often driven by a desire for understanding—it is an attempt to make associations, to recognize sounds as familiar, to slot what we hear into known categories. In Affordance, the variations between the three channels of the work protract and complicate this listening experience. Hecker has composed a three-channel piece in part to interrupt what he has called “bifurcated listening.” With a two-channel work, a viewer would be able to stand centrally and listen to the entire piece at once; with three speakers, movement and memory are necessary for understanding the piece as a whole.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
