audioXpress November 2023 Takes You to the Edge of Audio Development

audioXpress November 2023 offers an exclusive in-depth report on optical MEMS microphone technology from sensiBel, and understand how microphones can impact active noise cancellation performance. Learn how a new ADC Hybrid Gain Control IC enables smooth microphone preamp gain changes, and how to use DSP for hearing enhancement applications. Explore a Motion Feedback (MFB) approach enabling effective active desktop subwoofers, and recap on a century of Home Loudspeaker Development.

At CES 2023, TDK InvenSense introduced the T5838 and T5837 PDM MEMS microphones that offer 68 dBA SNR consuming only 130 µA in always-on mode and 330 µA in high-performance mode. The company also announced the new SmartSound One development platform that provides a plug-and-play evaluation interface for its MEMS microphones, and the new VibeSense360 hardware and software solution suite for advanced true wireless stereo features.

CUI Devices announced the addition of two MEMS microphone models purposely designed for active noise cancellation applications. With the industry increasingly requiring array configurations to enable processing of the audio signals captured by MEMS microphones in true wireless earbuds, headphones and headsets, the Audio Group of CUI Devices designed new models with high signal-to-noise ratios (SNR) and high acoustic overload points (AOP).
