分析FFT，LPC等变换，对信号处理的经典算法进行分析-Descr iption and detailed explanation on Fourier Transform, some FFT, LPC etc. Runable project demonstrates DCT transform on continuous audio, show and edit audio source with different zooming and view.

线性预测分析是最有效的语音分析技术之一，在语音编码、语音合成、语音识别和说话 人识别等语音处理领域中得到了广泛的应用。语音线性预测的基本思想是：一个语音信号的 抽样值可以用过去若干个取样值的线性组合来逼近。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。-Linear predictive analysis is one of the most effective voice analysis technology has been wide
