DSP Concepts Adds delResearch's Data-Over-Sound Technology to Audio Weaver

DSP Concepts announced it has added delResearch's AirModem to the Audio Weaver feature set. AirModem offers a secure wireless alternative to Bluetooth and allows for two-way data transfer between phones, computers, and other connected devices without the need for specialized hardware: just speakers and microphones. AirModem packages years of sophisticated software research and development into a plug-and-play solution that can be added to any smart product design instantly with Audio Weaver.

Anytime we need to login to the local Wi-Fi or pair with another Bluetooth device, we think, "There must be a better way to do this!" That's precisely one of the exciting possibilities for data-over-sound technology. This article explains what else we can do with it, and how it works. It also explores how data-over-sound can be realized in embedded scenarios, and how Chirp’s new technology, using the Arm Cortex-M4 and Cortex-M7 processors, can be implemented in connected products. This article was originally published in audioXpress, November 2019.

Chirp, the pioneers in data-over-sound, have joined forces with one of the leading companies in human machine interface (HMI) hardware and software solutions, Synaptics, in an effort to bring low-powered connectivity to consumer smart home devices. The collaboration targets seamless smart device experiences by embedding Chirp’s data-over-sound software into Synaptics’ edge computing SoCs.

Chirp, the pioneer of data-over-sound technology, and DSP Group, the specialist in wireless chipsets for smart-enabled devices, announced a turnkey solution leveraging embedded data-over-sound to improve user experiences with enhanced provisioning for consumer applications. The design kit combines Chirp’s ultrasonic signaling protocol for smart-enabled devices with DSP Group’s SmartVoice technology to allow connectivity between nearby devices without requiring any set up, pairing, or configuration.

Chirp, the company that pioneered data-over-sound technology, announced its support of Arm Cortex-A and Cortex-M based architectures, enhancing device-to-device connectivity on any Arm-based product with audio capabilities. This follows the recent release of Chirp’s Arm SDK, which provides a software-defined acoustic data transmission solution, optimized for Arm processors and substantially lowers the cost for applications such as device provisioning, proximity detection, 2-way acoustic NFC and telemetry in RF-restricted environments.
