PCM1864-Based Circular Microphone Board (CMB) Reference Design

Description

The PCM1864 circular microphone board (CMB) is a low-cost easy-to-use reference design for applications that require clear-spoken audio: such as voice triggering and speech recognition. This TI Design uses a microphone array to capture a voice signal: and converts it to a digital stream that can be used by DSP systems to extract clear audio from noisy environments.

Features
  • Uses two PCM1864 4-channel audio ADCs to interface with eight microphone arrays to extract clear speaker voice from noisy environmentsEnergySense notification for signal presence and loss – central part of a low-power: high-performance audio solutionOffers a complete system reference design using microphone array: TI-provided software: and evaluation module
