音频信号处理，主要完成对于音频信号的滤波，内含自己编写的低通、高通和带组数字滤波器源码-Audio signal processing, mainly to complete the filtering for audio signals, including the preparation of their own low-pass, high-pass digital filter and source code with group

MATLAB仿真设计树形结构滤波器组 并将原来语音文件与滤波接收后的问价进行对比 能实现功能-MATLAB Simulation design tree structure filter bank and the original audio file and filter asking price after receiving comparison function can be realized

在matlab中设计不同阶数的FIR滤波器,并对音频文件进行读入，分别对左声道和右声道进行滤波，分别满足35阶FIR滤波器和315阶FIR滤波器，输出音频文件，并进行滤波效果的对比。(In the MATLAB, FIR filters with different orders are designed, and the audio files are read in. The left and right channels are filtered respectively, which s
