is a multi-granular synthesizer that uses an artificial neural network trained with sound samples from the coastal areas of isolated islands—Hakrim-do and Ulleung-do—in South Korea. These islands have been mapped as sound particles within a latent space, enabling users to freely explore and listen to their coastal environments. The synthesis process mimics the natural degradation of styrofoam, blending nature with artificial elements to reflect the integration of marine debris into the natural world. We employed granular synthesis to illustrate how plastic breaks into small pieces by waves and wind, merging with natural materials on the coast. This process mirrors granular synthesis, where sound is divided into particles and new sounds are created by adjusting grain size. The instrument is designed for precise manipulation, allowing users to navigate the latent space and select sound particles. The custom interface is user-friendly, featuring six knobs, a motion sensor, and a touchpad for easy control, enabling users to navigate sound sources, adjust time segmentation, and add effects. The instrument’s case has been 3D printed with algae-based filament, making it biodegradable. transforms the visual experience of the sea into an auditory one. Our aim is to promote environmental awareness in a lighthearted way with this playful instrument while also sharing and connecting our ideas with others.
