Arpal is a web platform that combines minimalist design, subtle interaction, and ambient sound to create immersive soundscapes. The goal of the project was to design a sensory experience where the interface fades away, allowing users to connect with different emotional states through audio. The interface prioritizes atmosphere over traditional functionality, featuring smooth transitions, intuitive gestures, and a visual system that breathes in sync with the sound. From information architecture to microcopy details, every element was crafted to invite contemplation, focus, or calm. This project explores how UX/UI design can orchestrate a deep emotional experience using the bare minimum.
