Title: Decaying Presence Medium: Recorded audiovisual works (MP4) using Three.js and WebAudio

Decaying Presence is a series of audiovisual works that invite the viewer into a state of attentive stillness, to look and listen with deliberate focus. In this work, I explore the complementary relationship between sound and image, asking whether it is possible to sense sounds that have not yet been heard, or to perceive images that have not yet appeared. Each variation within the same generative system reveals a distinct balance between silence and resonance, between visibility and absence.

Patterns derived from sound waveforms are animated and used to trigger additional sonic events. These motions are reintroduced into a feedback loop, generating unpredictable chains of reaction. Within this self-reactive structure, sound and image continuously interfere with one another, creating an experience that drifts between transformation and equilibrium.

The works were originally generated in real time using Three.js and the WebAudio API, synchronizing visual parameters and sound playback through internal triggers. The sound materials were created in Max/MSP using the method of vector synthesis, in which phase signals are plotted as XY coordinates. While the process was inspired by the principles of analog video feedback, I reinterpret and expand these ideas through GLSL within a digital environment. Through this approach, audio and visual information form a responsive circuit that sustains continuous generative motion.

This project continues my ongoing exploration of visualizing sound and drawing signals. When both sound and image are regarded as temporal patterns unfolding over time, visualizing the phase of sound becomes another form of listening. By shifting focus away from the strict one-to-one correspondence of oscilloscope-based works toward a more generative and synesthetic coexistence, I aim to examine the threshold between the audible and the visible, illuminating the act of perception itself. At its core lies what I perceive as the vitality of patterns, their capacity to transform and manifest across different sensory dimensions.
