循环冗余校验CRC（Cyclic Redundancy Check）是由分组线性码的分支而来，其主要应用是二元码组。编码简单且误判概率很低，在通信系统中得到了广泛的应用。重点介绍了CRC校验的原理及其算法实现。-Cyclic Redundancy Check (Cyclic Redundancy Check) is a linear code from the branch, its main application is binary codes. Coding simple misjudgm

AAC编码器的matlab实现，可以导出AAC编码中间过程的系数-Usage: Take a wav file (44100, Mono) and name it as original_input.wav or change name in main_aacencoder.m. 1. Open the file main_aacencoder.m to encode original_input.wav in ADTS AAC format. 2. Run the f
