们知道，声音的频谱范围约在几十到几千赫兹，若能利用程序来控制单处机某个口线的“高”电平或低电平，则在该口线上就能产生一定频率的矩形波，接上喇叭就能发出一定频率的声音，若再利用延时程序控制“高”“低”电平的持续时间，就能改变输出频率，从而改变音-We know that the sound spectrum in the range of tens to thousands of cycles per second, if we use program to control an exit lin

用于显示男声，女声，高音，低音，以及变音后的频谱及原声图。完全放心使用即可！-Used to show male, female, treble, bass, and after the change the sound spectrum and acoustic map. Complete ease of use can be!

描述如何处理语音波形信号，对波形信号进行频谱分析，以及静音检测-Descr iption about how to deal with voice character and VAD Detecion.

一种基于自适应子带频谱熵的稳健性语音音端点检测，自己写的，希望对大家有帮助。 -A robustness of the voice tone endpoint detection based on adaptive sub-band spectral entropy, write your own, we hope to help.
