Yes, CUE has patented technology that enables data transmission over audio signals. This ultrasonic audio trigger technology was the foundation of CUE's original Light Show product and allows experiences to work even in venues with poor WiFi or cellular connectivity. While many clients now use CUE's web-based Global Sync triggering method (which became available after iOS opened Torch access in web browsers), the audio-based approach remains valuable for specific use cases. These include theme park applications where accessibility features or multiple language support are needed, as well as venues that lack reliable internet connectivity. The audio triggering works by embedding inaudible tones in the venue's sound system that phones can detect and respond to.
