如何从麦克风获取当前录音音量读数？
如何从麦克风获取当前录音音量读数？我指的是麦克风录制的声音的响度。我已经在 MSDN 上搜索了几个小时，但没有结果......所以，我很感激您的帮助。
How can you get the current recording volume reading from the microphone? By this, I'm referring to the loudness of the sound that is being recorded by the microphone. I've searched MSDN for hours, but to no avail... So, I'd appreciate the help.

实际上，我认为没有比使用较旧的混音器或较新的 WASAPI API 获取一些音频（即开始录音）并自己确定音量（即信号强度）更简单的方法了。为此，您可以轻松计算均方根，它等于平均信号力量。
Actually, I think there is no simpler way than to obtain some audio using the older mixer or newer WASAPI API (i.e. start recording) and determine the volume (i.e. signal strength) yourself. For this purpose, you can easily calculate the root mean square, which is equal to the average signal power.
“自己确定音量”是指：开始录音，然后使用单独的线程打开录制的文件，拖尾并确定幅度？因为这听起来相当复杂并且过程繁重 - 如果您不是这个意思，那么如何获取录制的音频呢？
By "Determine the volume yourself" do you mean: start recording and then use a separate thread to open the recorded file, tail it and determine the amplitude? Because that sounds fairly complicated and proc heavy - and if you don't mean that, how else to get at the recorded audio?
