利用小波变换对语音信号进行压缩，小波函数db5,分解级数5

构造小波基的Matlab源代码，来自小波图像压缩教程-Construction Wavelet Matlab source code, from the wavelet image compression tutorial

此程序主要是通过使用小波达到音频压缩的目的，可以比较不同的小波函数和压缩次数音频文件的差异-This process is mainly achieved through the use of wavelet purpose audio compression, you can compare different compression of the wavelet function and the difference in the number of audio files

根据对所输入的png格式的真彩图像、小波类型（db9或haar）和相应的阈值进行了三级非标准小波harr或db9的分解和重构，从而达到了对原图像的压缩处理的 -Entered based on the true color of the png format images, wavelet type (db9 or haar) and the corresponding threshold for the three non-standard or harr wavelet decompos
