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 environments
- EnergySense notification for signal presence and loss – central part of a low-power, high-performance audio solution
- Offers a complete system reference design using microphone array, TI-provided software, and evaluation module
