Voice for True Wireless Earbuds, GaN, and More Exciting Audio Frontiers in audioXpress April 2022

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.

Adding a valuable perspective to the topic of True Wireless Stereo (TWS) earbuds and hearables development, Jean-Marc Luneau (7 Sensing Software) details meaningful new features and improvements for brands to differentiate their products and make them stand out in today’s crowded market.

Startup company Duolink Go just launched its first product campaign on Kickstarter with an interesting design concept. Duolink Go debuted the world's first SpeakerBuds all-in-one design, combining true wireless earbuds and a two-part charging case with in-built speakers. The product differentiation is actually smart, since it offers a larger battery and charging case for TWS, which also serves as a single compact Bluetooth portable speaker or a separate (stereo) pair when opened.
