Recording Multiple Sources @ the Same Time

[Rise]

Heyas,

I do commentaries for video games and what I need to be able to do is record the game sounds + the sounds from my mic (me talking) at the same time in order to make a video. Fraps is what I use to record the game sounds and audacity records my mic sounds. Is there a way for audacity to record both of these things at the same time? I know it's possible since Procaster (streaming software) will record video + game sounds + mic sounds all at the same time and stream it for me but I haven't found an easy way to do it outside of that.

I also have the problem of not having stereo mix being an option in my sound control panel, or the option to record what you hear. All invisible/disabled devices are shown in the control panel.

How can pro-caster do this but I can not? Does audacity have the ability to do this?

To do that in Audacity you need to either:

1) Use "Stereo Mix"/"What U Hear" (not available on some Vista/Windows 7 computers)
2) Use an external mixer so that you can output the game sounds into the mixer and plug your microphone into the mixer and plug the mixer output into the Line in of your computer.
3) Record on a second computer or other recording device
4) Use virtual routing software such as "Virtual Audio Cable" to route all of the sounds into one audio stream.

How can pro-caster do this

I'm speculating as I don't know Pro-Caster, but I presume that it includes virtual routing within the program.
