Is there any way to record the sound output of a specific program on Windows? I already have a solution that uses WASAPI's loopback device to record all audio output to the speakers, but I would prefer to be able to record only the audio output of a specific program and ignore everything else. I assume this is possible using a virtual audio device, but I would like to avoid something so complicated if possible.

4Indeed, in Win7 each app has its own channel in the windows audio mixer. I wonder if they're accessible... +1 – spender Aug 09 '12 at 23:42

According to this post (which is very interesting in itself), there's a program called
Virtual Audio Cable which might do the trick for you....

Virtual Audio Cable will do what you already mentioned when you said it captures all audio sent to it. You can a Virtual Line to be the default and then record that Virtual Line. You can Not select a specific program to do such a thing. I have made a tutorial for using it. https://www.youtube.com/watch?v=WUQmkgw8Pjg I use it to play music from youtube through my "mic" while playing games.
