摘要
实现了基于低功耗Hi-Fi音频处理芯片Belasigna300和具有USB2.0控制器的微控制器STM32F103的语音采集处理系统。讨论了传声器阵列信号的采集、传输、片上处理及存储。系统体积小,音质好,功耗低。
A speech collecting and processing system based on low power Hi-Fi audio processor Belasigna300 and Mierocontroller STM32F103 with USB2.0 controller is realized. The collection, transportation, processing on the chip, and storage are discussed. The system has the features of small size, better voice quality and low power consumption.
