OTTOsonics: Designing and implementing an open and affordable 3D spatial audio system
Published online by Cambridge University Press: 01 October 2025
Abstract
OTTOsonics is an open hardware platform developed by a team of engineers and composers, designed to prioritise affordability and flexibility, addressing the needs of a broader community interested in spatial audio. At its core, the platform features a custom-designed, high-quality 4-inch speaker with a 3D-printed cabinet, and an affordable multichannel power amplifier. It also offers a comprehensive set of mounting accessories and a knowledge base for producing and presenting spatial audio using open-source software. Over the past three years, OTTOsonics has been adopted by multiple cultural initiatives, universities, and audio enthusiasts, enabling the production of new spatial audio works across genres such as electroacoustic, experimental, and pop music. This article outlines the key decisions made throughout the project and presents the technical and artistic outcomes after three years of operation. We discuss the key features of an open platform for spatial audio and how our designs address these needs, as well as future directions for further projects and initiatives.
