最近总是遇到调音量和选择录音通道方面的程序，我从网上下载了一个音量控制类，但在不同的操作系统有时会出错，我修改了里面的错误，重新封装成dll类，并提供详细的测试程序。没什么技术只是为了方便使用。 不过这个类在某些操作系统上对录音通道选择时还是会出问题，比如明明是选择"Mono"录音通道，可他却选到其他通道了， 我用了DirectX自带的例子程序也不能正确选到想要的录音通道，不知道如何能准确地选择需要的录音通道，若有高手知道请不吝赐教，我的E-Mail:chrys@163.com，多谢！(recent encounter always stressed the volume and channel selection recording of the procedures, I downloaded from the Internet by a volume control category, but in different operating systems sometimes be wrong, I revised the inside of errors, dll encapsulation into categories, and to provide detailed test procedures. No technology is meant to facilitate use. But in the category of some systems of recording channels to choose or will be problems, For example, she choose "Mono" recording channel, but he elected to the other channel, I used the example of DirectX, bringing their procedures for the election not to want to correct audio channel, do not know how to accurately select the desired audio channel, if experts know Help us to assume my E-Mail : chrys@163.com, thank!)

ree(void *p)函数是用来释放程序动态申请的内存。其参数是个指针类型。在C当中，只有当使用了动态内存申请函数malloc calloc realloc申请内存之后，才可以使用free来释放之。释放之后就不能再使用了。(ree (void* p) function is used to release the program dynamically allocated memory. Its argument is a pointer type. In C, only apply when using the dynamic memory functions malloc calloc realloc application memory before you can use free to release it. After release no longer use.)
