Cristian Subirà explores interspecies communication through sound and vibration during his research residency at Eufònic 2025

How can we listen to what doesn’t speak? With Signal Extraction, sound artist and filmmaker Cristian Subirà turns trees into receptors of waves and vibrations to explore new ways of communicating with the natural world. A research project blending technology, landscape, and ecology that questions the invisible noise of our era.

During his residency in the Ebre region, Subirà has further developed this project, drawing on historical experiments —like those of George Owen Squier, who used trees as radio antennas— and reimagining them through the lens of contemporary sound art. Somewhere between sci-fi and acoustic archaeology, Signal Extraction becomes an invitation to listen through silence and to challenge the acoustic extractivism imposed on the land.

From Barcelona to the Delta, via Finland: a cross-species project in progress

With a background that spans documentary filmmaking and experimental music —from dublab BCN to labels like Stroom and Aguirre— Cristian Subirà builds hybrid practices that blur disciplines and expand formats. His work doesn’t seek to romanticize nature, but to understand how it is affected —and shaped— by our technologies.

This summer, the research continues in the forests of Finland. There, in Sipoonkorpi, Subirà will keep working with trees as frequency receivers, in a practice that questions the legality and limits of noise pollution. A project that doesn’t just speak about nature, but dares to speak with it. Attentively, respectfully, with a finely tuned ear.
