Analog Devices Presents New-Generation ADAU1797 Low Power Audio Processor at CES 2024

Analog Devices is now sampling its latest audio processor and low power ANC codec, the ADAU1797. This high-performance device with integrated HiFi 3z and FastDSP cores is able to efficiently support front-end audio processing with beamforming and noise reduction, as well as neural network-assisted speech recognition (ASR) processing. An ideal, low latency, low power, three times more powerful processor for true wireless stereo (TWS) ANC earbuds and headphones.

audioXpress December 2023 includes a market overview of multiroom audio, Brent Butterworth writes about new ways to measure ANC earbuds, and Stuart Yaniger measured the new Axign and GaN Systems Class-D audio amplifier board. Richard Honeycutt writes about tubes, BJTs, JFETs, MOSFETs, and ICs, and Dimitri Danyuk, discusses JFETs in audio circuits. Douglas Self explains how to optimize variable-frequency tone controls, and Jan Didden shares his eDD direct-drive amplifier project.

The April 2022 issue of audioXpress offers an overview of voice for true wireless stereo earbuds with contributed articles from Knowles and Fluent.ai. Stuart Yaniger reviews the possibilities with GaN amplifiers, and Steve Temme explains the evolution of Rub & Buzz measurements and the latest perceptual algorithms. Ethan Winer designs a sample & hold circuit for a guitar-controlled, all-analog synthesizer project, Richard Honeycutt explores the meaning of “frequency response” as applied to rooms, and Mark Driedger explains why and how to test tubes.
