Description

The PCM1864 linear microphone board (LMB) is an easy-to-use reference design for applications that are cost sensitive and require clear-spoken audio, such as voice triggering and speech recognition. This TI Design uses a linear microphone array (up to four) to capture a voice signal, and converts it to a digital stream that can be used by a DSP system to extract clear audio from noisy environments.

Features
  • Uses two PCM1864 4-channel audio ADCs to interface with four microphone arrays to extract clear speaker voice from noisy environments
  • EnergySense notification for signal presence and loss – central part of a low-power, high-performance audio solution
