How to record from 'Wave' or 'Stereo Mix' in Windows 7 and Vista?
Hi all,
On Windows XP or earlier, I could capture the audio stream to the speaker not from the external device (maybe endpoint device in Vista) like the microphone. In other words, DirectSoundCapture was able to capture from the selected recording device/source line in the Windows record control utility or mixerXXX APIs. And if "Wave Out Mix" or "Stereo Mix" or something similar was selected as recording source line, DirectSoundCapture was able to record the audio stream to the speacker.
However, I could not find the way to do that in Windows Vista and Windows 7. Windows record control utility in Windows 7 and Vista is just showing only external devices (endpoint devices) like mic., line-in or S/PDIF in but I could not find "Wave Out Mix" , "Stereo Mix" or something similar.
I thought they were not seen because these kind of recording sources are NOT "endpoint device" on the user's point of view. So, I wrote a simple test code using "Device Topology API" of Core Audio APIs in Windows Vista SDK, in order to get internal controls of audio device. And one audio device driver (I have two Vista test system) exposes IAudioInputSelector interface. However, there's also NO "wave Out Mix" or similar subunit found.
Is there another way to capture the audio stream to the speaker on Windows 7 and Vista? Please let me know!!
