[SCM] voice2.0

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.

[Voice Compress] sub-band-coding

Description: 子带编码是一种以信号频谱为依据的波形编码方法，首先用一组带通滤波器将输入信号按频谱分开，然后让每路子信号通过各自的自适应PCM编码器（ADPCM）编码，经过分接和解码再复合成原始信号。-In sub-band coding is a waveform signal based on the spectrum coding method using a first set of band pass filters to separate an input signal spectrum, and so that each signal path through the respective adaptive PCM coder (ADPCM) encoding, after tap and then combined into the original decoding signal.
