fft
- 实现正弦信号的采样和快速傅里叶变换，效率非常高，可以运行。-Sinusoidal signal sampling and fast Fourier transform
LPC-based-speech-signal-processing
- 本程序利用MATLAB对信号进行分析和处理，主要就是进行语音线性预测通过使实际语音抽样值与线性预测抽样值的均方误差达到最小，可以确定唯一的一组线性预测系数。-This procedure using MATLAB for signal analysis and processing, mainly for voice linear prediction by the actual voice sampling error of the mean square value and the mini
ADPCM
- TXT信号的获取：一般都是拿到一个.WAV的信号，用cooledit或者其他的打开，另存为txt格式，注意的是，此时txt文件的前面两行会写入一些采样率的信息，将这几行删掉，程序就可以顺利得读取你保存的txt了。-TXT signal acquisition: generally get a .WAV signal, with coolit or other open, save as txt format, note that at this time txt file in front of
