Known for designing immersive spaces that transport visitors, frenchCALIFORNIA is integrating an acoustic technology component into residence 909. Apple's HomePod mini speakers are incorporated throughout the space, and were specifically chosen as a platform for frenchCALIFORNIA to integrate Berlin-based AI sound wellness app Endel into the residence. Using Spatial Audio on the devices via Endel, frenchCALIFORNIA chose an immersive soundscape to envelope visitors as they enter the residence, encouraging potential buyers to imagine the home as a place in which to unwind and relax.
