在噪声环境下语音信号的增强，效果不错的，而且比较简单，易于理解-in the noise environment to enhance the voice signal, the effect good, but relatively simple, and easy to understand

又一种新的97小波的C代码实现 可以参考一下-Also a new 97 wavelet C code can refer to realize

编写此文件的目的在于能将以前收集的一些歌曲和地址(本地的和网上的)生成一个能在播放音乐的软件自动播放的列表文件. 因此需要播放软件的支持.-preparation of this paper was able to previously collected some songs and address (local and online) to form a capable of playing music software automatically broadcast a list of documents. So players need the support of the software.

These are the source codes of the book, Frazier M W. "An Introduction to Wavelets Through Linear Algebra" [M]. New York: Springer, 1999. I wrote them in 2007. All the figures in the book can be reproduced by scripts. Enjoy it.

音乐，电子音乐合成。12分律 1.在钢琴演奏中G音的和弦我们常用G7和弦.不用G和弦.为什么?  2.在乐理中G7和弦5724组成音中2音省略只用574为什么?(和声学中五级七和弦省去第五音) 在12平均律中音的频率 G4=392.00Hz B4=493.89Hz D4=293.66Hz F4=349.23Hz  在纯律中音的频率 G4=396.00Hz B4=495.00Hz D4=293.33Hz F4=352.00Hz  在纯律中D音二个的频率.一个由G和弦产生297.00Hz另一个由Dm和弦产生293.33Hz  G4=396 D=396x3/2/2=297 (钢琴无这个频率)  A4=440 Dx3/2=440 D=293.33 (5度相生律.12平均律.纯律皆D=293)  当前G和弦 D4音=293.33Hz故不会合谐.当D4音=297Hz 才会合谐所以G和弦不会合谐  G7和弦才会合谐.因此有经验的作曲家在配合弦时常用G7和弦而不用G和弦.
