The two tech firms have demonstrated zero-power data-over-sound acoustic networking. This connectivity breakthrough allows devices integrating Vesper’s microphone to receive data via Chirp’s ultrasonic audio protocol.
The device can receive data even if it is initially in a ‘zero power’ standby state, leveraging the microphone’s advanced power saving capabilities and Chirp’s customised acoustic protocol to wake the device.
“This combination represents a major breakthrough for battery-powered devices requiring extreme low power connectivity,” said Chirp.
Using a mobile iOS app and an Amazon Echo Dot-style consumer device, the companies demonstrated the ease, speed and low power requirements of using data-over-sound and Vesper microphones together. Use cases include things like controlling Spotify music and smart meeting room sign-ins.
“We are very excited to be working with Vesper to show how seamlessly data-over-sound can work with Vesper MEMS microphones, and are thrilled to be demonstrating this at CES,” commented James Nesfield, CEO at Chirp.
“Data-over-sound is being recognised more and more widely as a frictionless way to transmit data, and is being integrated into a growing number of products.”
Matthew Crowley, CEO Vesper, added: “We are excited to be working with Chirp to help deliver a seamless data transmission experience for consumer devices, bringing a new set of capabilities to powered devices. It’s fantastic to demonstrate both technologies working in conjunction at CES.”
