ADPCM的matlab算法，很简单，一般人都能看懂。-Matlab the ADPCM algorithm, is very simple, ordinary people can understand.

The ADPCM package is a flexible simulation tool for an adaptive differential encoder and decoder with backward predictor adaptation. It uses an LP-based (Burg) adaptive predictor and a nonuniform quantizer with mu transfer function. It generates the
