校正任意形状DCT变换的矩阵不归一化，PSNR提高，基本是最佳校正方法-Calibration of arbitrary shape DCT transform matrix is not normalized, PSNR improve, the basic is the best correction method

In this paper the analysis of the compression process was performed by comparing the compressed signal against the original signal. To do this the most powerful speech analysis and compression techniques such as Linear Predictive Coding (LPC) and Dis
