正弦分析程序，用于通信语音质量分析，C语言编程，源代码-Sinusoidal analysis procedures for communication of voice quality analysis, C language programming, source code

语音建模直接影响语音识别，语音增强等后续工作，这里语音信号利用正弦模型进行建模，仿真结果良好-Voice Modeling a direct impact on speech recognition, speech enhancement and other follow-up work, where the use of sinusoidal model for speech signal modeling, simulation with good results

傅里叶变换能将满足一定条件的某个函数表示成三角函数（正弦和/或余弦函数）或者它们的积分的线性组合。利用傅里叶变换可对语音信号消噪。-ourier transform to meet certain conditions can be expressed as a function of trigonometric functions (sine and/or cosine functions), or their integral linear combination. Fourier tran

正弦波的PCM编码以及自己录制的语音信号的PCM编码-PCM encoded sine wave PCM encoding and recording their own voice signals

读入数据文件（例如：bluesky.wav）,叠加上一个不同信噪比的正弦信号(Read into a data file (e.g., bluesky.wav) and overlay a sinusoidal signal with different signal to noise ratio)
