Yasunao Tone… in his “Molecular Music” (1982-85): photoresistors were taped to the surface of a screen onto which a film was projected; each photoresistor controlled the pitch of an oscillator, and the resulting sound mass responded directly to the change in projected image. ~ Nicolas Collins, Handmade Electronic Music, pg. 165-166.

Pulse Width Modulated Light and Audio Transmission

Modulating four LEDs using Arduino and PWM.  Each LED fades at a different rate creating varying light patterns.  The fading light was then recorded using two powered photocells (one for left and one for right) which produces the rhythmic sound patterns.  As the sensors are moved further away the signal diminishes simulating interference between the receiver and emitter.


Spectrogram of audio recording:

The intent is to use the qualities of natural and artifical light, patterns of light, and movements of light to inform the building’s materials, form, and experience.  Patterns and openings in material allow light to be structured as it enters a space, creating a composition for the photocells to record.  Light can easy be interrupted and/or distorted by passing users, traffic, and site conditions.  This creates both an audio and visual composition dependent on its surroundings; one that may have missing and/or altered signals, varying intensities, or no light at all.

Transmission of sound through light:

Light is used as a speaker emitting various pulses that correspond to the sound being played.  When a photocell is amplified and placed near the LED, the pulses can be heard as the original sound.  Light is transmitting the audio signal.
