PCM1864CMBEVM Circular Microphone Board (CMB)

Texas Instruments PCM1864CMBEVM 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 reference design uses a microphone array to capture a voice signal and converts it to a digital stream. This signal can be used by DSP systems to extract clear audio from noisy environments. The reference design uses two PCM1864 4-channel audio ADCs to interface with eight microphone arrays. This combination extracts a clear speaker voice from noisy environments. This board offers a complete system reference design using a microphone array, TI-provided software, and evaluation module.
