Enabling Lossless Spatial Audio in Wireless Headphones Using Integrated Wi-Fi

InnoPhase IoT, a semiconductor company specializing in ultra-low power Wi-Fi, and GreenWaves Technologies, the company pioneering ultra-low power AI and DSP processors for hearables and connected devices, announced the development of a lossless audio reference design for Wi-Fi headphones. In collaboration with Danish pioneer IDUN Audio, InnoPhase and GreenWaves have created a platform that enables Spatial Audio for hearables and headphones with extended range and long battery life.

GreenWaves Technologies will be at CES 2024 with an interesting showcase of AI for audio applications. The company's GAP9 advanced AI processor is in volume production, and GreenWaves will be able to show several solutions that are enabling market leading hearable products. Demonstrations include audio advanced source separation models, and active noise cancellation with neural network based acoustic scene detection, as well as immersive 3D sound.

Originally presented at the Audio Engineering Society (AES) New York convention in 2018, the release of the DeMIX Pro software established a strong new contender in the field of audio separation. Meanwhile, AudioSourceRE has used machine learning to take the concept further, while the latest version 5 of DeMIX Pro and DeMIX Essentials has set a new standard for AI-powered audio separation, making the unimaginable totally possible. Now, AudioSourceRE is working to offer the same technology, running in real-time embedded systems!

GreenWaves Technologies, a fabless semiconductor company based in Grenoble, France, has received the funding needed to support the production of its second-generation GAP9 processor. As demonstrated at CES 2023, this advanced AI processor revolutionizes the next generation of true wireless earbuds, hearables, and connected devices with ultra-low latency noise cancellation, neural network-based background elimination and 3D sound.

A wave of new developments promises to solve the most pressing need for people with milder hearing loss, allowing mass-market hearables to supplant Over-the-Counter (OTC) hearing aids with less stigma. Andrew Bellavia suggests the FDA’s OTC hearing aid rule (October 2022) includes assumptions that are quickly becoming obsolete as recent developments illustrate.
