CUE- Data Over Audio

CUE- Data Over Audio

Overview

CUE uses ultrasonic, inaudible sound to connect you to your audience without having to rely on Wi-Fi, Bluetooth or cellular service – or any additional hardware.

The CUE protocol is the next generation of Audio Content Recognition (ACR). By relaying data through inaudible, high-frequency sound waves, metadata can be embedded into any music or television broadcast, or even played silently without any accompanying audio.

Review


Together with Ever Technologies, we were able to clear our workload, automate our client services, and build out our client portal.

JAMESON RADER

Founder at CUE Audio


We have an internal team building out our client portal but in order to speed it up we brought in Ever Technologies.

They worked very well with our internal team, doing coordination meetings 1-2x weekly and as needed.

We used Trello to manage our tasks and Ever Technologies had no trouble adjusting to our workflow.

All in all, the project lasted over one year and was budgeted for more than $50,000.

Ultrasonic Push Notification


Broadcast proximity messages from any speaker without the need for Wi-Fi, cellular service or Bluetooth. UPNs can be embedded into any music or television broadcast, or even played silently without any accompanying audio.

Offline Data Transfer


Send arbitrary data payloads through sound waves. Our Offline Data Transfer protocol is resilient to noisy environments, including large stadiums, and can transmit over 100 meters. The data payload can then be leveraged to achieve any custom, desirable action on the receiving device.

ODT is extremely secure, as the signal is isolated to the room in which it is broadcasted. As the ODT signal never occupies the electromagnetic spectrum (think Wi-Fi, cellular service and Bluetooth), it is impenetrable to many traditional hacking techniques. Traditional encryption methods like SHA-256 can be applied to the data as an additional layer of security.

Ultrasonic Proximity Awareness


Using only existing speaker infrastructure, users’ locations can be triangulated. Tailored content can be displayed depending on the user’s current location, or referencing previous regions he or she has visited.

Ultrasonic Authentication Protocol


Any user ID, password or username can be transmitted via CUE’s Ultrasonic Authentication Protocol. A typical concert ticket can be transmitted in roughly one tenth of a second.

This can help speed up long queues for check-ins and even eliminate specialized ticket scanners.

Ultrasonic Wayfinding


GPS and BLE location services provide only rough approximations of user location, especially indoors. CUE’s Ultrasonic Wayfinding UWF) services allow positional triangulation, using only existing speaker infrastructure — no additional hardware required.

Tailored content can be displayed depending on the user’s current location, or referencing previous regions he or she has visited.
