可以用来测量线路回声消除效果的matlab程序-lines can be used to measure the effects of echo cancellation procedures Matlab

本人收集的有关音频的加密文章，希望打搅喜欢-collection of the Audio encryption articles, like disturb

mfcc, 语音信号梅尔倒谱系数提取。MFCC，Mel频率倒谱系数的缩写。Mel频率是基于人耳听觉特性提出来的，它与Hz频率成非线性对应关系。Mel频率倒谱系数(MFCC)则是利用它们之间的这种关系，计算得到的Hz频谱特征，MFCC已经广泛地应用在语音识别领域

一个基于DirectSound的声音播放器，VC++开发，可直接运行，喜欢的朋友可以拿去试试。-DirectSound-based voice player, VC++ Development, can be directly run, like a friend can take a try.

一个可以生成音乐文件播放列表的文件，是俺自己做的呀-one can generate music playlists in the paper, I do for myself ah

完成pcm 16位线性与pcma律转换的几种源码！-Complete pcm 16-bit linear conversion with the law several pcma source!

这个设计范例展示了如何使用DE2-115 开发板以及一个PS/2 键盘和扬声器，来实现多音电子 键盘。 PS/2 键盘模拟钢琴键盘用于输入按键信息。DE2-115 上的FPGA 芯片用来实现音乐合成器， 生成不同音调的音频信号。连接到DE2-115 开发板上的VGA 显示器用来显示按键动作。

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.
