title: Virtual audio driver (microphone)
body: <p>I want to develop a virtual microphone driver. Please, do not say anything about DirectShow - that's not "the way". I need a solution that will work with any software including Skype and MSN. And DirectShow doesn't fit these requirements.</p>
  
  <p>I found <strong>AVStream Filter-Centric Simulated Capture Driver (avssamp.sys)</strong> in Windows 7 WDK. What I need is an audio part of it. By default it reads avssamp.wav and plays it. But this driver is registered as WDM streaming capture device. And I want it in Audio Capture Device.</p>
  
  <p>There are some posts in the web but they are all the same:</p>

  <p>I think registering this filter-driver as audio capture device will make Skype recognize it as a microphone and thefore I will be able to push any PCM file as if it goes from mic.</p>
  
  <p>If someone already faced this problem before, please help.</p>
  
  <p>Thanks in advance.</p>
