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

打开文件,设置声音输出格式,设置声音输出频率,保存声音改变后输出的文件名-Opens the document, the establishment sound output form, the establishment sound output frequency, after preserves filename which the sound change outputs
