Matlab实现对正弦波采样的线性内插，及上采样过程。-Matlab to achieve sampling sinusoidal linear interpolation, and the sampling process.

实现正弦编解码（Sinusoidal coding)的matlab程序 sinusoidal_analysis.m文件定义了函数[A, F, P, fs] = sinusoidal_analysis(filename, framelen, frameshiftlen)，将*.wav音频文件提取出A, F, P这3个参数矩阵。 sinusoidal_synthesis.m文件定义了函数syspeech = sinusoidal_synthesis(A, F, P, fs, framelen
