Meyer Sound announced that it is providing the spatial audio foundation for sound artist Bill Fontana’s Resonance, a site-specific installation created in collaboration with Grace Cathedral, San Francisco, as part of its ongoing commitment to innovative intersections of art, spirituality and public life.

“What you’re experiencing is the building becoming a listening device,” said Fontana. “It gives the impression of being almost like a living spirit in the building.”

The company said that the project aims to transform the cathedral into an immersive environment with live signals captured from the bells and organ pipes. Fontana developed the installation using sensors mounted to the cathedral’s bells and microphones placed inside silent organ pipes. The Meyer Sound system serves to amplify and spatialize those live signals, revealing subtle harmonic activity normally imperceptible to visitors and shaped by the surrounding environment. The installation is part of Grace Cathedral’s 2026 Year of Resonance, an exploration of sound, space and spirituality through public art.

“One of the things we love about Grace Cathedral is the way sound decays,” said Malcolm Clemens Young, dean of Grace Cathedral. “You play the last chord on the organ, or the choir has that last burst of energy, and then you listen as the sound rolls through the building, bounces off the back wall, and comes back to us. What Bill taught us is that there is no moment when that stops.”

Meyer Sound’s spatial and digital audio specialist, Leonard Blanche, deployed eight pole-mounted ULTRA-X20 point sources and four USW-112P subwoofers throughout the cathedral. Using the Galileo GALAXY Network Platform and the Spacemap Go spatial sound design and mixing tool, Fontana worked with Blanche to route and shape signals from the bells and organ pipes across the interior, treating the architecture itself as part of the composition.

Meyer Sound said that the project continues a collaboration between Fontana and Meyer Sound that has included installations at St. Peter’s Basilica, London’s Tate Modern and other projects. Resonance remains installed at Grace Cathedral through Sept. 20, 2026, inviting visitors to experience the cathedral as a living resonant instrument.

“I’m doing works where I’m exploring musical patterns in the real world, in natural and urban human environments. And in order to kind of make that come to life, the loudspeaker systems are a crucial element,” said Fontana. “Meyer Sound has developed the most amazing tools to control large-scale loudspeaker installations. I feel very privileged that they will work with me on realizing these ideas.”
