代码说明：
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.)
