Description: 基于stm32的数字化语音存储与回放系统的软件设计。该系统经过拾音器采集语音信号，经带通滤波与AGC后，进入AD，然后数据存入SRAM，再由DA送至带通滤波，由喇叭将语音信号恢复。该系统可以很好的存储与回放语音信号。，
本源码是在mdk上开发的。 软件设计分两个模块：压缩解压编码与存储模块。压缩编码有PCM编码和ADPCM编码两种可用按键选择；存储是FSMC存储（256k flash）存储。-Stm32 of digital voice storage and playback system-based software design. The system has been collecting voice signal pickup by the bandpass filter and AGC, into the AD, then the data are stored in SRAM, band-pass filter is then sent by the DA, to restore the voice signal from the speaker. The system can be a good storage and playback voice signal. , The source is developed in mdk. The software design is divided into two modules: the compression and decompression coding and storage module. Compression PCM coding and ADPCM encoding the two available buttons store is the the FSMC store (256k flash) storage.
