Sonicdraw is an interactive web app that translates drawings into sound in real-time. Lines, shapes and airbrushes are intuitively mapped to sound oscillators, noises and filters, enabling visitors to explore visual textures and quickly create looped sound pieces. Visitors are invited to share their finished sound drawings and explore the work of others in an online gallery. Sonicdraw is inspired by the role of sketching in architecture and design as a creative tool for generating ideas and structures. Since Iannis Xenakis’ seminal graphical interface UPIC, many compositional tools have been developed that map sketchs to sound and generative music. These interfaces have proved successful in the contexts of collaborative and individual music creation and sound design.
