Audio Crossings is an interactive sound installation that translates visitors movements into live sonic intersections within a spatial experiment. Multiple distance sensors placed around a grid of screens trigger sound events as people move closer or step away, continuously altering the loudness, timbre and spatial placement of the audio sources.

At the heart of the work is a mapping of sensor input to synthesis parameters. Distances become controllers that either add or subtract layers of sound, change grain rates in granular synthesis, or push content into subsonic ranges that are felt as much as heard. The palette ranges from near silence to dense noise, from clear pitched material to fractured textures that disintegrate and recombine.

Technically the installation links artistic intent with signal control. An interactive patching environment processes sensor values and maps them to parameters such as amplitude, filtering, grain size and panning. Specific locations in the surrounding space cause crossings of audio sources, producing additive interference or subtractive interaction through phase and filtering. Visitors do not merely observe sound, they sculpt it with their bodies, producing a kinetic composition that is always ephemeral and unique.

Developed as a postgraduate project during 2023 2024, the work investigates shared intervention in public and semi private spaces, the interplay between movement, technology and acoustic perception, and the idea of sound as a social field to be negotiated. The installation invites experimentation, provokes curiosity and lets each participant feel the subtle and extreme shifts of a responsive environment.
