Download the CUE audio file for your new product, which contains inaudible, ultrasonic signals. Do not modify this lossless audio file in any way.


Convert any speaker into a smart speaker by playing your audio. The audio file will initiate your product on any nearby smartphone running CUE.


From synchronized light shows to Ultrasonic Push Notifications that enhance content for viewers at home, CUE's products help you innovate.

By utilizing existing speaker infrastructure, a proprietary ultrasonic communications protocol, and the hardware fans bring in their pockets, CUE routinely synchronizes crowds of 20,000-120,000, captures the world's largest simultaneous selfies, choreographs spectacular smartphone light shows, and hosts massive multiplayer trivia games. Millions of live event attendees download and engage with CUE's live event product suite each year.

Broadcast Application

While bluetooth signals cannot be embedded into a broadcast, CUE's data-over-ultrasonic-audio protocol enables on-screen content to communicate seamlessly with nearby devices in a manner completely imperceptible to the viewing experience; moreover, this is accomplished without the need for pre-cataloguing audio, as required by ACR services.
