说明：  该源码是对 *.wav语音波形文件做去直流电平，归一化处理后进行ADPCM编码压缩，形成编码文件和编码文件转外存格式转化，并利用编码文件做输入，进行解码并生成 *.wav 。该程序算法已经在产品中应用。
(The source is a*. wav file to do voice waveform to DC-ping, normalized after treatment ADPCM coding compression, the formation of coding documentation and coding documents Core format conversion, and make use of document input encoding, decoding and generates* . wav. The program algorithm has been applied in the product.)
