PCM
- 中文称脉码调制，由A.里弗斯于1937年提出的，这一概念为数字通信奠定了基础，60年代它开始应用于市内电话网以扩充容量，使已有音频电缆的大部分芯线的传输容量扩大24～48倍。到70年代中、末期，各国相继把脉码调制成功地应用于同轴电缆通信、微波接力通信、卫星通信和光纤通信等中、大容量传输系统。80年代初，脉码调制已用于市话中继传输和大容量干线传输以及数字程控交换机，并在用户话机中采用。
mp3解码说明文档
- mp3解码.doc 在主控模块开始运行后，主控模块将比特流的数据缓冲区交给同步及差错检查模块，此模块包含两个功能，即头信息解码及帧边信息解码，根据它们的信息进行尺度因子解码及哈夫曼解码，得出的结果经过逆量化，立体声解码，混淆缩减，IMDCT，频率反转，合成多相滤波这几个模块之后，得出左右声道的PCM码流，再由主控模块将其放入输出缓冲区输出到声音播放设备。
