49040380LPC
说明: 线性预测编码(LPC)是主要用于音频信号处理与语音处理中根据线性预测模型的信息用压缩形式表示数字语音信号谱包络(en:spectral envelope)的工具。它是最有效的语音分析技术之一,也是低位速下编码方法高质量语音最有用的方法之一,它能够提供非常精确的语音参数预测。(linear predictive coding)

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 two lines will write some sampling rate information, will These lines deleted, the program can be smooth to read your saved txt.)

滤波器设计
产生一个连续信号,包含低频,中频,高频分量,对其进行采样,进行频谱分析,分别设计低通,带通,高通滤波器对信号进行滤波处理,观察滤波前后信号的频谱。(The filter is designed to generate a continuous signal containing the low, mid, and high frequency components, to be sampled, for spectral analysis, respectively, to design a low-pass, band-pass filter processing is performed by a high-pass filter on the signal, the spectrum of the signal of the observation before and after filtering.)
