单看界面就感觉很牛！完全仿真Windows系统的高级音量控制功能，系统音量、波形、声道平衡、线路输入、CD唱机音量等都可控制，很实用的实例源码。-Just look at the interface on the cattle feel! Complete simulation of the high-level Windows system volume control, the system volume, waveform, channel balance, line input, CD player can control volume, etc., are practical examples of source code.
