speccorrect
- 在FFT后信号的频率往往与谱线不相重合，而在两条谱线之间。为了要求得信号的频率、幅值和初始相角，必须要使用修*来完成。这里给出一种修*。
soundsignal
- 将声音文件在时间轴上分割成几段，分别将段的秩序及某些段内的秩序颠倒，从而实现了对声音文件的加密。首先，先读取一个声音信号，对信号做1024点FFT变换，取完点之后，分成四个向量，四个向量组成一个矩阵，再对每一个向量进行转置，再重新整合，从而就实现了回密的过程。-Sound files on the timeline will be divided into paragraphs, each paragraph of the order and reversed the order of some
