WHISPER™ MK-I
The WHISPER™ MK-I isn’t just advanced, military-grade hardware—it’s control over sound itself. A next-generation directional signaling system, it delivers messages with surgical precision: across a room, down a street, or directly into the ear of your audience. Your message goes exactly where you intend it, delivered with precision.
THROW YOUR VOICE.
Precision over volume.
sound from silence
WHISPER™ uses modulated ultrasonic carriers that travel silently through air, with no audible output at the source. When the beam encounters a nonlinear medium — a wall, an object, or even the human body — the signal self-demodulates and reconstructs into audible sound. This effect allows the system to project audio into space as if the air itself were a speaker, while remaining inaudible outside the target path.



Ultrasonic Precision
A dense transducer array concentrates energy into a tightly collimated ultrasonic beam. Beamforming keeps dispersion under a degree, enabling long-range delivery without significant spread. Because ultrasound propagates in a highly linear fashion, WHISPER™ maintains directionality over distance, producing clear, intelligible sound only where aimed and preserving silence everywhere else.
Targeted Delivery
Sound is not broadcast. It is placed. Every watt measured, every degree calculated. Output remains consistent and repeatable, with minimal influence from ambient noise. A WHISPER™, delivered to a precise address.
