Audio preprocessing system reference design for speech-based applications

This reference design uses multiple microphones, a beamforming algorithm, and other processes to extract clear speech and audio amidst noise and other clutter.  The rapid increase in applications that are used in noise-prone environments for voice activated digital assistants creates demand for systems that extract clear voice from noisy environments.  The reference design uses a microphone array and a sophisticated signal processing to extract clear audio from noisy environments.

Capacitive Touch Remote Control Reference Design With CapTIvate™ Technology

The touch remote control enabled with CapTIvate™ technology demonstrates a capacitive-touch solution based on a single MSP430™ microcontroller (MCU) with CapTIvate technology. This design uses self- and mutual-capacitance technology to enable a multifunctional, capacitive-touch panel (buttons, slider, gesture pad, grip sensor and proximity sensor) for smart TV, settop box, and sound system remote applications for future application extensions with various communication interfaces available. The design allows operators to extend the battery life by the low-power active and standby modes.
