Echo

The machine transforms sound into a visual form, linking parallel realities. It interprets sound by converting it into intricate, ever-changing imagery. At times, it documented sound based on emotions, but when processed through the machine, that emotional layer was removed, creating a neutral, objective visual representation.

The construction of the machine is based on a system of three interlocking wooden gears, each rotating the next in continuous motion. As the gears turn, they trigger a device that activates specific sounds. These sounds are then transcribed through the machine’s motion. The rotating gears adjust a connected tracing arm that flexes and moves, with a pencil at its end tracing complex shapes onto a surface. The position of the tracing arm on the gears determines the forms it produces, causing the patterns to shift dynamically as the mechanism moves.

While the resulting shapes may seem unpredictable, they follow a precise logic dictated by the interaction of sound, movement, and mechanics. This interplay creates two simultaneous yet distinct realities—one shaped by human perception, the other by pure mechanical translation of sound. Together, they form a new way of experiencing sound, giving it shape, motion, and depth beyond just hearing.

Process to Product

By adjusting the bolt locations and the sound device, the machine traced an entirely new image, producing a more oblong and elongated shape.

We utilized our digital fab lab and CNC-cut the sound visualizing machine’s key components. Custom gears ensured smooth motion, the tracing arm translated movement into patterns, and custom-cut bolts allowed fine-tune adjustments—all digitally designed for precise functionality.

The result

In this instance, each full rotation of the gears triggered a high-pitched sound that faded in and out. When people hear high-pitched tones, they often associate them with sharp angles and short, abrupt lines rather than smooth, continuous curves. However, the machine’s mechanical process defied this expectation, translating the sound into structured patterns dictated by the turning gears. This contrast between auditory perception and visual outcome highlights the tension between emotional interpretation and mechanical representation.
