使用matlab的waveread函数读入两个.wav格式的数据文件，采用补零或截取方式使它们具有相同长度，然后分别完成序列的延迟/超前/加/标乘及卷积运算，对运算结果采用wavwrite函数写为.wav文件并加以播放(或用sound直

接播放)，分析上述操作对序列的实际影响

-Use of matlab waveread function reads two. Wav format data files, using zeros or intercepting a way that they have the same length, and then complete the sequence, respectively, the delay/advance/plus/standard multiplication and convolution of the calculation results using wavwrite function is written as a. wav file and play them back (or sound direct playback), analysis of the actual impact of operations on the sequence
