sound modulation

Infrared absorption methane concentration alarming device is comprised of microcontroller systems, light modulation module, signal conditioning module, digital display module, sound and light alarm module, remote control receiving module, standard output module interface circuit.

该红外吸收式的甲烷浓度报警器由单片机系统、光源调制模块、信号调理模块、数码显示模块、声光报警模块、遥控接收模块、标准频率输出模块等电路组成。

And it considered that dynamic modulation makes sound speak and makes sound sound out.

引申的“声音”,并且认为动态调制的目的就是让声音自己说话,让声音发出“声音”.

Also contains a beat box tool, modulation tool ( to make the sound less perfect, more real), stream to disk recording, real-time effects and response.

也包含了一个拍子工具，调制工具（声音少点完美，多点真实）输出到磁盘保存，实时效果和响应。
