Since 2010 Gilbert's practice has centered around his original software, SpectralGL, an interactive listening instrument that generates real-time visual landscapes in response to sound. Building on earlier work as a composer, sound designer and lifelong technologist, his creative output probes the phenomenological nature of listening itself through a practice centering on improvisation and collaborative dialogue. His work has been featured at numerous concerts halls, festivals, and projection-mapped installations across the world.
Gilbert co-founded Dark Matter Media LLC in 2007, as a vehicle to support his independent creative work, as well as an active consultancy around emerging technologies deployed in a range of public and private settings. From 2011-2017 he was the founding Chair of the Department of Media Technology at Woodbury University, and has taught interactive software design at both CalArts and UC San Diego.
